Hi All!

So, I bought a '70 CB350 a year ago, took it apart, and brought it up to Toledo to work on it. I've found that my time has been stretched extremely thin between going to school and working here in Cincinnati, so I have had no time to work on it as I had planned. I bought a 1984 Honda Aero 125 to scoot around town with, but I've quickly found that it leaves power to be desired. So, this past weekend, a kind gentlemen by the name of Scott sold me this fine piece of machinery that he's taken care of for the last 5 years. Here's some of the upgrades he's done:

- New stator and generator.
- Electronic ignition
- cables, headlight work, small things like this

As I've said in my other posts, I'm a true beginner. I'm looking for something that requires enough attention to where I will be forced to learn about the bike, but not enough to where I can't ride.

Yesterday, my buddy and I were trying to kick start it just for the hell of it. I he was on the left, I was on the right. I thought the kick stand was down, so after my failed attempt, I let it lean to the left a bit, to which it did not stop leaning. We got it up in about two seconds. There was oil leaking from the stator cover, which there was a dime sized hole in from the shift lever being pressed against it. So, I'm thinking all I need is so either get a new lever or bend it back into shape, and then weld the hole on the plate. I have a few questions, though.

- Is welding the best option? Should I just try to find a new cover? I tried looking on ebay, but I didn't have much luck. Are those covers the same for many models? Would the one from my 350 fit? Could I get cheap one from a cb450 Night Hawk or something?

- Are there any good replacement levers out there? I'm not sure how to tell if an aftermarket one will fit or not, or if they're all pretty standard.

- Is there anything else I should make sure is okay? Is it possible the clutch is damaged from the pressure placed on the lever?

As always, thanks so much for any input. You guys are the best.

Looks like the cover is the same for pretty much the same for all the DOHC 450s except maybe the K0 4speed (?)

The Nighthawk is a completely different engine, basically no interchangeable parts.

Welding, or repairing with JB Weld, is an option.

Hey JT,

Thanks!!! Searching for that specific part number has helped, I should have thought of that initially. Any thoughts on if the clutch might damaged at all? Before I took the lever off, it did still seem to change gears properly, so I assume that's a good sign.

So, I'm going to take advantage of my buddy who is on the robotics team here at UC and use the welding equipment he has access to and his skills. I just ordered a new shift lever from CMC, so we should be back in business by Friday. Hopefully nothing else was damaged on the fall. I'm extremely paranoid!!
