    WTB: CB360/350 starter clutch housing

    looking for a new starter clutch housing for my CB360. Mine has dents in it from the pistons pushing on the outer housing so it doesnt work well anymore. I learned that the 350 and 360 use the same clutch housing so either would work. There are some on ebay but everyone sells it with the starter...

    Another CB360 charging issue thread (solved)

    I'm having some really weird charging problems with my 360 that I'm hoping someone could help with. When I start it up, charging seems fine. But after riding about 1/4 mile down the road the volts start to drop. It goes down to ~12.5 vdc and doesnt climb with revs and stays that way. I have a...

    Cb360 starting/running issues. Fresh 378 rebuild

    Freshly rebuilt 378cc 360 with new harness is very hard to get running. Need help! When it does start running I have to keep the throttle fully open or it stalls. It never gets above idle rpm range. Noticed some fuel splashing out the back of the carbs when it's running as well. So I thought...

    CB360 - new drive chain. Will it fit?

    I bought a new drive chain for my CB360 and it is wider outside to outside than the stock chain by a few milimeters. How do I know if the chain is too wide? the motor still isnt in the frame yet so I cant just hook it up to see if it rubs against anything. I could, however, test fit it on the...

    Rear fender swingarm mounting

    I've been doing a little contemplating on how I'd mount a rear fender to the swingarm of my CB360 and so far I've decided on a design that seems like it should work. I'm using a fiberglass fender so the mount doesn't need to support much weight. But I do understand that it will be subject to a...

    Electrical conversion question

    I have run across a couple toggle switches that only advertise amperage at 120v ac. One I found (below) advertises 5 amps @ 120v ac. Is there a way to convert the amps to 12v dc? Forgive my ignorance when it comes to electronics. I searched online and couldn't find anything. Here's the switch...

    WTB CB360 Crankshaft NO LONGER NEEDED

    NO LONGER NEEDED. THANK YOU. I'm looking for a CB360 crankshaft in good condition. Mine seems to have decided to chew up some metal so I don't want to put it back in the motor.
