1972 CB/CL350 - trying to keep it classy

Re: 1972 CL350 cafe build

Rewelded...I'm getting better (shocking, I know). Tips welcome! Actual MIG welding beats the heck out of flux core. I actually had fun doing this. This is my second time ever welding. I think I may like this!
Narrowed the front a bit to come in smaller than the RD tank. The taper is about 8 deg or so and then a hard bend about 3 inches before the end. It look almost straight in this photo... hmmm I also tried my hand at filling a decent size gap.
My dang bobber has really taken a lot of my time recently.

Re: 1972 CL350 cafe build

Relocated the tank mounts to accommodate the rd400 tank and trimmed the heck out of the stock cl350 rubber mounts to fit the newly "C'd" existing rd400 tank mounts. I measured about a million times to make sure I had a flush line from the rear to the front as well as the 1/2" from the bottom of the frame line to the tank/seat line. Nialed it, thank God.

Hopefully I get a sander for Christmas so I don't have to do all the body filler sanding by hand... :-\
 
Re: 1972 CL350 cafe build

Today I made some good progress. I welded in what is now a brace and the holder of the rear seat mounts, hacked the excess off of the back of the frame, made a tray for the battery box and electrical to sit under the hump, and filled in a pretty big gap at the rear tips with the welder. I am pretty proud of that, being new to welding and only having a welding how to book to go by. :eek: Every time I pull the trigger on that welder I get better. Thank God!
I sanded and primed the frame to keep it from rusting. This brought out some cosmetic flaws in the frame that I will be fixing.
I made the front seat bushings from new blank door stops that I ground down and drilled through. The rears are made from MK3 Jetta rear/upper coilover bushings! ;) They are actually perfect for this application. I still need to trim down the bolts...

Re: 1972 CL350 cafe build

Did a little test fitting to see what size shocks to buy, etc. Most of the parts used here will be replaced or made nice. I am going to trim the frame in the rear to make a continuous line from the tail to the frame. I also may be cutting down the hump to match the height at the end of the gas tank. I will be using clip-ons so that gap from the triple tree to the tank will be filled. Also going up a bit on the shock length.
Your thoughts/suggestions? Thanks!

Re: 1972 CL350 into a racebike?!

Back from the dead!
I broke down the engine. Once my filter cup socket comes in I will be splitting the case.
I think I will be building this for the Sportsman-350 class. I will now be making a mold of the tail and going fiberglass to save weight.
Can anyone verify the rocker box differences in the CL and the CB for me? I was looking at cams and I am reading conflicting info...
Thanks. Pics in a minute. 8)
 
Re: 1972 CL350 gone race bike

I just ordered a boat load of parts, including a Big Bore 67.5mm kit from Bore-tech! Should be fun! Hopefully I will have a fully built race bike by next season.
I will be doing all of the standard race mods/tricks. I will be talking with an old fried (he's 70) who used to flat track back in the day. Hopefully he can help me out with race motor wisdom.
Everything will be even further dismantled and thoroughly cleaned, of course.

I will also be making a scaled down, fiberglass version of the steel seat to save on weight and better fit my aesthetic taste.

Re: 1972 CL350 gone race bike

The past year was packed full of craziness: bought my first house, had a slow/small brain bleed (BMX racing is for kids, fyi), a broken elbow and hand along with surgery to fix, and a ton of project ADD, and finally getting back at this project.
I am pretty sure this will just be a toy for me. No racing or anything. It is actually a lot more appealing to me now that I can do whatever I want and there is no deadline.
I finished up the inside of the engine. Did all of this the right way with a lot of cleaning, measuring, cleaning, measuring, and some cussing. ;)

Yesterday I finished up the frame and went with the taboo method of appliance paint. It looks great to me. I am very pleased. After a couple weeks I will lay some more on it.

I did an acid bath for the chrome bits I'll be using. Some parts are beyond saving...the chrome part of them anyway. I may go with the new fork tubes from Forking by Frank. He just called me with a price yesterday: $275, plus shipping.

Next up is polishing all of the aluminum parts and buying my VM30's. We have momentum!
 
Re: 1972 CL350 build

Got the new All-Balls bearing races pressed into the frame. I decided to quit messing with these cruddy, pitted old fork legs and just bite the bullet and pay Forking by Frank for some new purty ones.
I also ordered my new rims and spokes. ;D
 
Re: 1972 CL350 build

After becoming borderline obsessed with the Royal Enfield Classic over the past couple of months, I have decided I would rather build this thing close to stock looking...but not. I think I'll use my CB350 frame and have a lower profile version of the original seat made. I'll still be doing aftermarket exhaust, headlight, gauges and, of course, the motor I have labored on for so long. Oh yeah, and these sweet wheels. 8)

Glad to see you back at it. I really liked how you made the seat from an extra "scrap" tank. Real old school stuff that.
