"A Bird in the Hand" take 2. DR650 Deadtail Bobber

Re: "A Bird in the Hand" take 2. DR650 Deadtail Bobber

I find the same thing. It makes sense, the smaller the item the smaller the profit. If someone really needs to sell a pair of stock handlebars and is going to go through all the trouble of setting up a sale etc for 10 bucks they must really need it (for meth lol)

I've got a DR for sale on CL at the moment and it's a PITA just with all the damn people asking me questions all day. It's cheap, buy it or dont!




is this thing done yet?

All of the people I asked about carbs were the people that were parting out an entire quad and had something along the lines of "message me about what part you need". Most of them weren't selling just the carb, but were parting the entire machine.

And not done yet. The wife just had knee surgery on the 15th, so I've been helping her 5% of the time and trying to keep a rambunctious 9.5 month old from climbing on her 95% of the time lol

I dare you to try and sell a GZ250 on CL and Marketplace.

The carb finally came in, which was the last piece I was waiting for before I could start building the frame cradle.

I decided that it was to nice of a day not to ride the bike to work, but I also wanted the engine there so that I could tinker with stuff on break, so on the back of the BMW she went. She rode 25 miles in without any issue =)

So enters the inspiration bike. I really loved the proportions, so I took a known dimension (the o.d. of the front rim) and scaled the rest of the bike as close as I could. Now I know the picture is at a slight angle, so its all just rough dimensions, but it'll get the proportions close. If your curious, its sitting at a 32 deg rake angle and a 60" wheel base with right at 6" of frame ground clearance.

I should be soon ready to start bending some tubing and making motor mounts.

I think you have a good plan going there. The girder forks will look great on there and, having spent a day on your DR a year ago, I know that lump is more than up to the task of giving you a big, stupid grin every time you swing a leg over. I know there's a certain look and style involved in the design of a bike of this type, but I hope you are able to find a tank that'll give you a good look but still have some decent capacity. Don't know about you, but I hate having to stop for gas every hundred miles or so!

Scaling off the inspiration is an excellent idea. That is one of nicest XS650s I've seen.

Im just here to listen to excuses as to why the RD and Minibike aren't being worked on

The way i see it, you sold your RD, so you only have the merit to ask me about the mini bike

Yep, I'm still a fan of this power plant. I can't say that I haven't thought about going with the 760 Big Bore Kit and big valve head excetera excetera but if I do that will be down the road a-ways. If this thing ends up being as lightweight as I would hope the stock lump with the pumper carb should motivate it along just fine

i need a scan of that cable cover from your fcr mx mine is missing on my xr650l

that one looks the same i could 3dprint one that color matched

Got a bit done today. Made up some multi purpose mounts. They hold the engine in place as well as locate the bottom frame cradle in the jig and adjacent to the engine. When I'm done with this project they will be the stand that the hollow mockup engine sits on the end table in the basement lol In the last pic you will see a mockup piece of tubing showing how the bent cradle will sit.

I've been chipping away at odds and ends over the last couple days. Firstly I cut, ground, filed and shaped away the excess garbage from the donor neck. I think that step took as long as everthing else on this project combined so far. I wanted to make sure that I didnt gouge into the tube past any welds, as it is about as thin of wall as I care to use anyways. (even so i managed a few small niks, that look worse in the pics.)

Next, the old south bend 9 earned its keep yet again by turning me out a few neck cones for the fixture.

That step allowed me to put the neck tube and rear axle in the final location/ angle. I threw a few tape lines up to get an idea of the overall shape. I like it. the engine needs to move foward about 1.5" still, but you get the idea overall. I think im going to have to bite the bullet and go ahead and order the tank before i get to build happy to make sure it fits the lines and backbone well.

 

[ridesolo]

Very nice! Impressive work so far.

I would eliminate the top engine mount and not run that tube above the head so close to the engine. Make it go from the bottom of the head tube to the backbone where the tank will hide it. What are you going to have for wheelbase with that setup, plus fork length. Seems tall and short from here. I know you have to clear the carb, but it looks like you can stretch it and drop the head tube and clear it the same amount.

Wheelbase is set at right at 61" 32deg rake and fork length is right at 29.5".

The tall and short gig is a bit what im shooting for. The frame is scaled off of the xs650 inspiration bike earlier in the thread. Once i put the scaled bare frame into auto cad, i also thought it looked a bit odd, but the high tunnel wassel helps. Also, the tape lines arent set in stone, but i will be running lower tube and a top engine mount. I will try to get most of it hidden under the tank, (again, like as in the xs650 picture) but this frame will be a single down tube going into a twin cradle. The upper motor mount should do a good bit to help stiffen everything up. I know its not gonna be a razor edge performance handling machine, but giving up the stiffness of the top motor mount being tied in seems pretty fruitless.

 

[Hurco550]

Ok, so i did a little more tweaking to the dimensions, and ended up dropping the target frame to ground clearance from the original 6" to 4.75". I also lowered the neck tube about 2", mainly so that i can throw the complete titan front end on it that i have laying around until i can get my girder forks done. The rake remained the same, but it will also adress a bit of the giraffe neck look that irk pointed out.

Here is the cad program drawing of the stance in its current ideration:

I made up another bit of fixturing to hold the down tube in place:

Planning on bending up the backbone tomorrow and getting it in place. The tape line shows where the backbone/hardtail will lay.:

 

[irk miller]

The CAD drawing looks the bizness.

 

[trek97]

Really cool stuff man.

 

[canyoncarver]

The drawing is much better. Whats the plan for the rear axle plate?
