Title: 66 Ducati 250
Post by: SeekingZero on Sep 06, 2013, 00:29:11
Since the CB175 (http://www.dotheton.com/forum/index.php?topic=34716.0) is almost complete, I thought I would unveil the next project.

8 months ago I sat down at Ducati Bike Night in San Jose, CA with a guy that happened to be parting ways with some of his old Ducati project bikes that he never got around to.  I told him to hang on to one for me and I would be back to get it.  Last week I flew back out there for work, made arrangements and the bike arrived at my house today.  It is definitely a bitsa that seems to have started life as a Monza, at least as far as the fenders are concerned.  It is a 5-speed model and seems to be missing only a few, though essential, parts.

I also met up with one of the most experienced men on the planet when it comes to the Ducati 250.  He's raced them, owned them , worked on them, and has a shop that's crammed with parts for them.  I took it by his shop out in Hayward, CA before I left and we spent the afternoon discussing the bike as well as what parts it needed to get running.  He has all the parts I need and I was able to barter a few now and will send for the rest later.  He also recognized the work that has been done on bike and knows the guy that did it.  Based on that, he said that the motor is more than likely set up to race!

I am not sure which direction to go with this bike yet, but the first step is to get it running then rolling down the road.  After that I may see where I want to take it.  Stay tuned for more!

What a great find.  Best of luck to you on this classic.  From shoes to bikes, no one can match the Italians for style, especially with the oldies.

I would love to get my hands on one of those 250/350 singles.

I would go for the Scrambler look ;)

Full Fairing Racer
(http://seekingzero.com/wp-content/gallery/ducati-250/1965-ducati-250-gp-replic-1_600x0w.jpg)

Right now I'm leaning towards Half Stock or Racer (/w optional full fairing 8) ).

Do I need to get a poll going!?  ::)

I am leaning between half stock and racer as it is now.  However, first things first, and that is I need to get it running...and running well.  Then I'll start cleaning it up.

And whats this about getting to it someday...where are your priorities!

Great find!  They seem to be quite desirable.

I like the half stock option- one of the ones I ended up is that way and it too is a '66 square narrow 250 . . .

That one looks really nice.  I'm so torn.  I like the Monza look, and since I have the fenders it would make sense to go that way, but I also love the Diana rounded look as well.  Decisions, decisions!

Wow, I am ashamed that I haven't updated this thread in so long. I apologize for getting everyone excited and then dropping off the face of the earth! Well, I supposed its time to try and redeem myself. I shall start by giving you all the latest updates. As of the last post, I had the money, motivation, but no time. I am happy to announce that I now also have the time!! I'm also back in California which helps immensely as well. I've lucked into an amazing living arrangement with two old racers that has worked out so wonderfully. However, we do currently have 8 motorcycles in the garage and so, even though I have a garage to work in, trying to complete a restoration in it was another matter entirely.

Therefore, I started looking around for some shop space that I could rent or use to do my work. Back in 2012, a place called Moto Shop opened up in South San Francisco. Moto Shop was a company that would rent or own large shop space as a base for a community motorcycle garage where anyone can work on their motorcycle, or take a workshop and learn how for a hourly, daily, weekly, or monthly rate. I looked them up again and wouldn't you know they changed their name to Moto Guild and opened a San Jose location (much closer to me)! Shop space solved. http://www.motoguild-sv.com/ (http://www.motoguild-sv.com/)

Last Saturday, I went and hooked up my trailer, with the 250 still sleeping inside, and drove about 15 minutes North to Hayward to meet with Chris Quinn, master wheel builder and vintage Ducati legend.

(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20160108_152945.jpg)

He remembered me and the bike and I spent 4 hours there with him, discussing the bike, tearing open the motor (for the first time!) and searching through is shop of endless old Ducati parts for some of the bits I still needed. We took off the clutch side cover, bevel side cover, and eventually slid the cylinder up to get a peak down below. What we found was incredible!

(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20160109_134919.jpg)

The crank was shiny and new, the valves and guides were all new and modified topped off with a high compression piston. The engine was built, and very well done, but had never been fired! We were able to figure out why too. Before we took the cylinder off, we rotated the motor a bit an kept hearing a consistent clunk. As we figured, the top of the piston was hitting the valves since the piston isn't stock. We took a walk into Chris' shop, he pulled out one of many cylinder shims in a drawer handed it to me and said, "take the cylinder off, put this under it, and put it back on." How awesome is that! Speaking of his shop, I snapped some photos of this vintage restorers wet dream...

(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20160109_132850.jpg)

After pulling a table full of parts out of all his stock, he tallied up what he wanted for everything, I handed him a few bills and was out of there with a ton of much needed and very hard to find pieces for an incredibly reasonable price. I'll post up the parts later on. With the bike, and my new box of parts, loaded up, I left for San Jose and Moto Guild. Moto Guild Silicon Valley opened in July of 2015 and is still very much getting started. The man running the show is Patrick and he is a very nice guy who was more than excited to have the little 250 in the shop. Turns out that he is also from Illinois and went to Eastern Illinois University, in the town I used to live in and owned my first house in for 4 years! Small world.

And I almost forgot, before I left Illinois, I was able to title the bike as a 1966 Ducati 250 Mark III (MK3 or MKIII). Regardless how the various pieces may have began life, the bike that I will own at the end of this restoration will look like the image below of the bike it is titled as!

I saw your thread revived as well! Your build definite looks promising and I hope all the customization turns out the way you want! I'm glad to not be doing any customizing this time around. Turns out that the "half-stock" picture is actually a completely stock Mach 1/Mark 3. So I will essentially just be doing a restoration that will happen to be cafe-esque!

The 250's and other cc models did come with jellymold tanks, but those are older bikes. The red 160 in one of the photos of Chris Quinn's shop is an example of an older model Ducati with a jellymold tank.

That's what I thought when I first saw it, but it hasn't got the right foot peg/kickstart/brake lever set up for a Mach 1. I'd bet dollars to donuts it's a "Mock 1"... nothing wrong with that though.

That's awesome! You should stop by. The place is still new and the more business it gets, the more fab stuff we can get! We are going to be doing soda blasting this weekend.

Nothing wrong with that at all. Mine will be a Mock 1 too! ;)  But I don't plan on leaving mine as a garage queen, I plan to ride it!

This week's update:

I dropped the frame and a bunch of other large bits off at my powder coater on Saturday to be sand blasted so they are ready for paint. I also to the wheels and hubs and will drop them off with Chris Quinn at Motorcycle Wheel Works in Hayward to have him work his magic.
(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20160116_141623.jpg)

With all of that out of the shop, all I had was the motor to work on. I still have to put the kickstarter assembly back in the motor, but without the clutch holder tool, I can't yet. So I spun it around and took a look at my points assembly.
(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20160114_195712.jpg)

The condenser is shot and I needed to clean up the rest to see what I was working with. I dropped it all and a few other things into my ultrasonic cleaner and waited.

(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20160114_203805.jpg)

The cleaner did it job wonderfully and so I put it all back together minus the condenser. I wasn't entirely happy with the state of the rest of the points parts so I ended up ordering an entirely new assembly since I needed a new condenser anyway. Next, I got to work on the outside of the motor to clean it up. I got some baking soda and started to make a mess...

It cleaned up pretty well. I'll finish prepping the engine for paint the next time I'm there. The first round of parts have been ordered so that I can complete the motor. I was also able to source some original fenders off of a Mach 1. As soon as I get the fenders, I'll be able to take it all to my painter! More to come.

This week's update:

I got the frame, tank, and other parts back from being blasted. Now I'm just waiting on fenders and the reg bracket so I can send it all for paint.
(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20160121_175812.jpg)

I've been back to Moto Guild about every day that it's open to work on various parts. I started cleaning up old parts to see what was going to be restorable and what I needed to replace. Between the ultrasonic cleaner, a wire wheel, and some metal polish, I've been able to make that determination easy!

(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20160124_172140.jpg)

I also got a clutch holder tool so that I could take apart the clutch side to install the kickstarter assembly and rewire the stator. Still waiting on the flywheel puller...

(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20160122_210741.jpg)

Once I get that I can button the motor back up and start on the suspension. I am going to shoot the motor with a coat of silver paint because although the cases are aluminum, I can't get them to clean up nicely and I don't know why. They should just be a nice uniform silver, but they are blotched with darker areas and marks. Maybe they just aren't clean enough. Oh well.

Last Saturday, I stopped by to see Chris Quinn again, picked up an original speedo and cable drive, VHB29C carb, and some other miscellaneous parts. He also had pre-polished cases that he would swap for cores and the cost of polishing. I got the right side plates and will need to get the rest later. So onto the carb...

Looks just a bit dirty, bottom cover nicely polished. Let's see what's inside!

(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20160123_174047.jpg)

Wow.

It took me a while to get it to this state. Lots of carb cleaner and WD-40. The float wouldn't even move for over an hour. All the parts have now been through the ultrasonic cleaner and cleaned up wonderfully!
(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20160123_174923.jpg)

I ended up having to cut the float off to get the pin out. Carb rebuild kit, float, and other goodies all ordered. And finally, I took out all the case and side cover bolts, wire wheeled them shiny to prep for nickel plating. I hope to try that this week. The shinier they are before plating, the brighter the nickel!

Ya didn't pull the swingarm (or center stand or bearing cups) before blasting it? I'd be worried about grit around the swingarm pivot. Sand blasing is nasty, if you leave any place for the media to hide you'll be dealing with it for ages... You need to pull that stuff to paint teh frame anyway. Also, I'd push the pivot out of the brake lever and lube everything up before reassembly to make it easier to remove the lever next time. I've had to cut the arm off one or two of those they were so seized up.

The shots of the engine have me itching to get to work on mine. I'm getting pretty close to where I can pull mine and start the refurb on it. I haven't decided how far to get into it though, I may mod it or I may just get it running again for now. I'm trying to save up some money for an 851... non-essential spending on the 350 has been suspended for the moment.

I'm not sure about the spots on your engine cases. My 160 cases weren't perfect either, but in use they get a lived in look pretty quickly anyway so it didn't bother me. FWIW judging by those pics yours look ok to me. Hit them with some aluminum wheel cleaner worked in with a stainless steel brush and they'll be fine. They will look even better the day after you do it. Along the way I used two different types of wheel cleaner and some carb cleaner on mine, in combination with the stainless brushes. This isn't the greatest pic of them but it gives a general idea of what they ended up looking like.

(http://www.teamyikes.com/160/Pics/bottomend_3027.jpg)

Sidecover bolts - I buy stainless versions from somewhere like Boltdepot.com.

And finally, you've probably already been told this, but do NOT brace that new clutch tool on the kickstart shaft. Trust me on that one.

No, I had them cover the bearing ends before blasting, I may end up taking it apart and ensuring everything moves well before painting. And like you said, I may need to have it pulled to paint anyway. I'll cross that bridge when I get there.

As far as the cases go, I have hit them with everything I've got, and its just not to my standards. But, I was talking with an old airhead restorer and they use Rub 'n Buff over the engines if they can't clean up as nicely as they want. This sounds like the ticket! Check out the thread from ADVrider.
http://advrider.com/index.php?threads/rub-n-buff-aluminum-or-pewter.838392/#post-19956746

I already got a nickel plating kit and I really want to see how it works out. I have and can replace any bolts with stainless allenhead if I'm not happy with the nickel plating. I'm looking forward to seeing your progress as well! I plan to have mine on the road by May!

A lot has happened in the last couple weeks. I've been by to see Chris a couple more times to get more parts. I also dropped off the wheels to be rebuilt by him. He will also have the hubs polished and I swapped him my side covers for some nice already polished ones.

In other news, I got the flywheel puller, removed the flywheel, and rewired the stator to 12V. I broke the ground between the two windings here:
(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20160127_191301.jpg)
(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20160127_192009.jpg)

Then layed them over a coil, not touching, and epoxied them down. Finally, I soldered in new leads to a homemade "harness", if you would call two wires a harness! Still trying to find a better, thicker sheathing to use.
(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20160127_192117.jpg)
(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20160129_192844.jpg)

With the stator finished, I reassembled all that and moved on to modifying the kickstarter assembly. Apparently these old Ducati's where notorious for having slipping kickstarters due to an 'engineering flaw'. Luckily there is the simple fix of drilling and threading another bolt into the main engine case as depicted in the guide below!
http://www.motoscrubs.com/Narrowcase_Kick_Start_Repair/Narrowcase_Kick_Start_Repair.htm

Chris had given me all the parts years ago so, with great care, I began.
(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20160130_125123.jpg)

(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20160130_133105.jpg)

Unfortunately, after all that I still have an issue with the face gear not engaging...but I'll sort that out later. You might have noticed the damage to the case in some of the images. That is from the kickstarter gear not having enough surface area to adequately stop on the case stub, so it eventually breaks off pieces of case, kick by kick. Again, there's a fix for that!

Around the time of my last post, I was recommended something called Rub n' Buff. Apparently, old airhead guys have been using it on their engines for longer than I've been alive to bring back the lust of the old weathered aluminum cases. So I ordered a $6 tube from Amazon. Oh the sheer joy and satisfaction this little tube elicits!

Here are some side by sides. See if you can spot the raw aluminum vs the Rub 'n Buff...

Yes, pewter is the color I ordered. There is a silver one also that matches a bright aluminum, but wouldn't be very good on engine cases.

Cool! I hadn't heard of that stuff, I'll have to try it out.

This might not help (and it looks like you're done already anyway) but to clean up the cylinder on my 160 I chucked it up in a lathe, spun it (not fast) and used sheets of Scotchbrite to clean it up. Much easier than doing it all by hand though probably not an OSHA approved use of a lathe…

Exchanged your sidecovers for pre-polished ones, huh? That's cheating!  ;-)

EDIT: I just checked out the link you provided about the kickstart spring fix. Surprise surprise, it uses pics of my 160 screw up as a warning to others! I'm still embarrassed by that… anyway, better to show others than to hide it and let them repeat my mistake I guess. I don't mind that they're there, it was just a surprise to see them.

Definitely try it out. For the cost, its worth just having it on hand! What I've learned from my previous builds is what I can do, what I want to do, and what I'm alright leaving others to do for me. Polishing is one of those things that falls into the latter category...

I knew that was a 160 in the pictures, I was thinking those photos looked familiar! Small internet huh?! Thanks for going through the headache so the rest of us can learn. That is predominantly one of the reason I take the time to post these builds.

More to come!

Alright, I have definitely been dropping the ball on updates again. Finally caught a little break this morning and decided to showcase the progress. I was able to source out the rest of the tin I needed and get everything ready for paint.
(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20160331_204712.jpg)

I fixed and cleaned up the headlight bucket and also got around to brazing the tank to fill the pin holes along the seams. Then it was getting the tank cleaned out so I could seal it. I had it sit with CLR in it for over a week to let that do its magic and test the integrity after the brazing. Turns out that there was still a leak but it was seeping out of the back of the tank from no visible pinholes. So, back to the brazing on the tank underside. With that fixed, I put the POR15 gas tank sealer in and it has cured wonderfully!
(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20160402_114131.jpg)
(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20160402_114141.jpg)

The last step before the parts would visit the painter was test fitting the pieces. The rear fender was the only piece that need modification for the new holes for the registration bracket. The painter now has all of the bits that will get color and I should have them back in 4 weeks or so.
(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20160416_165347.jpg)

(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20160416_165319.jpg)

I also picked up all the parts from the polisher! While picking up the parts from the polisher, I also grabbed the de-laced rims to clean them up.
(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20160416_152413.jpg)
(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20160416_153407.jpg)

I did not have the center of the hubs polished so that I wouldn't have to maintain them and opted to use the silver leaf rub-n-buff on them instead. The outside of the hubs is polished, the first groove is the rub-n-buff wiped on, and the other grooves are the rub-n-buff before wiping. Incredible, it looks like its been polished! I am so ecstatic about how well this rub-n-buff stuff works!
(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20160417_183247.jpg)

Of the bits from the polisher, most were the remaining engine pieces though I don't have any pictures of them all yet but I will soon enough. The next step is to button it up and maybe see if I can get it running! As it sits now:

Thanks for your comments guys! Doc_rot, you'll have to stop by sometime I'm there, though, until I can the pieces back from the painter, its just the engine to see. I'll be teaching a rebuild/restoration/cafe class at MotoGuild in the coming months, so if you're interested you'll have to get on their mailer.

I am excitedly awaiting paint, and stopped by the painter yesterday to snap some photos for research. He's getting everything prepped and is right on schedule!

I went to MotoGuild last night to see whether I would need to take the fork legs to the polisher or not. They looked to have been polished at one point...probably decades before I was born! Is the rub 'n buff that good?!
(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20160427_211938.jpg)

This bike isn't going to be a show bike. Bikes were built to ride, and ridden this bike will be, so I'm not to worried that it 'could look better.' I also pulled out the rest of the polished pieces and stuck them on the motor. She's finally complete and a thing of beauty...I'm almost tempted to make a coffee table stand out of it...almost!

Stunning really. That rub-n-buff stuff looks like it works pretty well, too. Will definitely give it a shot on my next build. Hell, I might get some and use it to clean up the 360 since I half assed the polish job  ;D

Before I order some, you mentioned you used pewter for the cases. What about for the front forks lowers there? Is that the 'bright aluminum' or still the pewter?

Yes, the pewter is on the cases and the silver leaf is what I used on the forks and hubs that seems to polish out nicely.

I know I've been away for far too long but not a lot has changed in the last few weeks. I got a Flitz buff ball for my drill to get the wheels to a nice shine before I sent them to Motorcycle Wheel Works to have them laced with all stainless bits. Once I saw the remarkable difference that the buff ball made, I dug into my parts box to see what else I could shine up.

(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20160513_213102.jpg)

This is simply some Wizard's Metal polish and the buff ball. It's amazing how well everything is cleaning up with seemingly little effort. I cleaned up the rear Ceriani's as well and found the one of my springs is bent. Looks like the bike had taken a spill in a former life. I'm going to see if a local shop can get me some replacement springs.

I love the before and after shots. Incredibly satisfying. Between the Rub n' Buff and the Flitz ball, this project is a piece of cake!
(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20160429_215255.jpg)

Currently, the wheels are laced and the tires have been mounted. I stopped by the painter's on Thursday and the frame bits in red are simply stunning. He is taking this project very seriously and becoming more OCD than I am! That is a great thing though and since the schedule for completion is at my whim, I'm not worried. ;) I should have a roller in a week or two.

Stay tuned for more!

you are doing fantastic work there as was said ealier you really should remove the swinger the bonus is getting it swinging nicely will improve the ride
the cerianis i can service them for you at a reasonable cost
and it needs to be doen even if they have had little use and aren't leaking, age sets in the seals are likely too dry and hard for much service
are you sure the shocks are straight? just spin the rods round and round and bent will be observed if so
the springs didn't get bent crashing they just took a set probably cheap quality some uneven heat treating
i have lots of springs suitable for those shocks some even in new black powder coat or even nos beauties
nothing real nice in chrome though
it would be wise to get a fresh pair of springs and ones correctly sprung for you

So before I got the front end assembled, I couldn't get the top triple to fit on the steering head because of the tapered bearings that were on it. Therefore, I got my hands on some original ball bearing races, some 3/16" ball bearings and easily put it back together like stock.

I stopped by the painter again last week and checked in on how things were going. I picked up the rear fender and headlight bucket. Those went on easy enough. Wheels together and no she's a roller!

Thanks guys!

doc_rot, you'll have to come by sometime that I'm there! I guess I keep missing you or I don't know that its you. Have you seen the bike there? Its usually under a blanket on a work table.

I'm fortunate to have a garage right now so I don't go in there except to use the tire changer. I haven't seen your bike in person, as you said it's been covered up.

Cool, you are very fortunate indeed. I have a garage as well, but it has too many bikes in it...I know, first world problems.  8) Feel free to send me a ping if you know you'll be by and are interested in checking it out in person.

Next update!

Things are moving right along as I continue to identify bits I still need and pieces that aren't quite working out. The seat bracket arms didn't quite want to fit in the frame right without rubbing a lot so I did a bit of vise bending to get them situated and put the seat on.

(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20160925_134600.jpg)
(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20160925_134619.jpg)

Then I put the spring on the center stand, added the countershaft sprocket and chain, aligned the rear end, and mounted the exhaust which needed a spacer not to hit the center stand.

(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20160928_192836.jpg)

I also put other bolts in there holes that I hadn't previously had, such as the swing arm shaft clamp, and started work on the rear brake pedal and foot pegs. The foot pegs I have may be too far gone to reuse and the brake pedal is a bit bent, so nothing is quite complete yet as i continue to check fitment.

(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20160928_192910.jpg)

So finally, I moved on to assembling the headlight. I just need to get the grommets for the bucket and wire everything in there. Waiting on a 12V regulator until I start the wiring.

Thanks again guys! I'd have more updates but I'm waiting for the last few parts to finish it up. Era-specific clip-ons have been hard to find but I've finally tracked them down. Once the 12V regulator comes in, I can fire it up. And the last thing that has been time consuming is fitting the cables on. Not much else left to do, so depending on my schedule and how many issues I run into, I could have this thing complete at the end of the month!
Title: Re: 66 Ducati 250
Post by: SeekingZero on Oct 17, 2016, 03:24:48
The last bits...so I think...have been ordered and most have arrived. The 12V regulator was among them and so the wiring has begun in earnest. I picked it up from Classic British Spares as one that is meant to run on the old Triumph's/BSA's and that lot. Its a 2-wire magneto + Pos & Neg that should do the job nicely. I also got a battery that should work as well, and got started tonight.

(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20161016_161130.jpg)

I ran out of both bullet connectors and time or I might have gone farther. Before I was done, I also wired up the tail lamp so that it will be ready to connect and tested it with a 12V dual filament bulb I had lying around that fit perfectly.

(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20161016_173432.jpg)
(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20161016_174350.jpg)

I still have to run the wires to the tail lamp, to the coil, to the brake switch, and up to the headlight and tie it all together in there somewhere. That's a job for future me...

I finished this build back in February and I can't believe I didn't give you all an update. Shame on me. In my defense, I've been really busy with a lot of awesome things!

Welcome to the final installment of the build! I left off with the wiring and that is where I will continue...in a bit. First, because its beautiful, I got the front fender put on as soon as I got it back from the painter.
(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20161020_191310.jpg)
(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20161020_191318.jpg)

Then put the seat badge on with some stainless rivets.

(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20161021_165851.jpg)

And the clip-on's arrived!

(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20161026_210601.jpg)

Now, onto the wiring after that easy stuff was done. I got the taillight mounted and wired to the brake light switch, which only works on the rear brake because safety standard of that day were a bit more lax, or the Italians thought that putting a switch on both brakes might have been too practical...

(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20161102_200542.jpg)

I then disassembled the light switch to rewire and diagram it.

(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20161102_200455.jpg)

Then ran the wires up to the headlight.

In retrospect, using just red and black wires gets tricky for a wiring diagram and tracing wires... Oh well. The wiring got done regardless.

(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20170126_211844.jpg)

I also decide to switch the chain guard out from the scrambler one I have to the Mach 1 style. I think it was the right choice. I got a piece of pipe foam for the tank spacing and it turned out perfectly!

(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20170208_160242.jpg)

I got the levers ordered and installed and just had to finish cutting the cables for each one. Once cut, I soldered the new ends on which was actually pretty fun. Here's a video!

https://youtu.be/FyzxJ019O2c

I tidied up all the wires and cables after that.

(http://seekingzero.com/wp-content/gallery/ducati-250/IMG_20170208_160246.jpg)

Then on to setting the timing.

Then adding oil!

Finally I was ready to start it.

https://youtu.be/HU39ISPm5TA

I realized after that that I couldn't get it to idle without choke that my timing was still off. Had to fix that and adjust the mixture a bit and it finally ran perfectly! And just in time for the tank!

Ladies and gentlemen, I give you a year of enjoyable work for me! There's an awesome guy that comes by the shop to take professional shots of the bikes as his hobby, so he got a couple of the little Duc for me. And then I thought it would be cool to pose it next to its younger big brother. 1966 vs 2006!
