Junkyard 74 CL360 Resurrection

New to the community with a first time total rebuild. The platform that I am working with is a Junk Yard find 74 CL360 I picked up for $100 bucks. It still had a 1976 license plate with a 81 registration sticker on it. I'm assuming it has been sitting since 81 or 82 so that's 32-33 years. Ironically when disassembling the bike I found the original owners manual and a bill of sale dated 1979 for the sum of $400.

Once you look past the rusted out gas tank, none existent seat with only a small rusted piece of the seat pan still attached to the seat hinge, missing and rusted out air boxed, rusted out tool holder seized front brake, broken and smashed head light, controls and levers missing and damaged, all cable missing or damaged, the tires dry split and falling apart, and coils are shot (wiring and accessories look like they're all in tacked but will be replaced as needed), all the important stuff was still in tacked and ready to be restored. The frame, motor, front forks, gauges, and wheels are all restorable. The bike is completely disassembled now and I've torn the motor apart. The motor didn't turn over but for $100 bucks I didn't expect it to. Once inside I found the cam chain tensioner guide broken in two, finding out that quite common, and the left side piston rings seized in the cylinder. I looked like something crawled up the exhaust and lived in there sometime in the last 30 years. I say the exhaust because the original spark plugs where still installed. I'm going to work on getting the motor back in shape, checking all the tolerances, bead blast all that I can, probably over bore the cylinders to 68mm, install new wiseco pistons, ect. then move to the rolling chassis. Stay tuned for periodic updated. For now see some of the current photos.

Re: 74 CL360 Resurrection to Cafe Racer

The natural patina on that bike is great. I'd say get it running and don't change much. If you were able to get the gas tank cleaned and coated it would be great as in, imo.

Good luck with that one -- I'm pulling for you. I started with one that was a little worse. Had both pistons seized; had to cut rusted chain off an angle grinder and tires off with a reciprocating saw. I ended up having to replace the jugs and the cylinder head with used ones from ebay. Got my rebuilt engine started a year ago March and am finally finishing up the last of the fabrication and welding to get it moving under its own power for the first time in 30+ years.

ya the patina is cool, however there is nothing on it that can be used by just cleaning her up. The tanks, well there's preatty much no bottom on it and I don't think a tank coating kit will seal all that. But thanks for your comment.

kosmot:

Thanks for the encouragement. The good thing is that I live in the south and haven't had to cut much of anything to get her apart. I had to massage the break hub on the front wheel with a rubber mallet, pry bar and generous helpings of PB Blaster and WD-40. I had to cut off the tool holder but it was rusted all to H#ll anyway. I had to dill out a few phillips head screws on the engine cases but with patience, good drill bits and an extraction bit all were removed successfully. All other bolts where removed without incident.

Update! Motor teardown. No more surprises, yet! Fingers crossed as I proceed.
