So I've got a '75 CB360 I've been trying to get on the road all summer. After screwing around trying to get it to run right, I'm at wits ends.
The carb's got rebuild with a set of Keyster kits, then the bike got a new set of coils, points, etc., and the top end of the engine got rebuilt (new gaskets, valve seals and rings). Floats are properly set, valve clearances are set, timing's set, carb's were benched synced and no rips in the carb boots, blah blah blah. Since then, the bike's started perfectly and idled fine. But acceleration and cruising above idle causes bad surging that makes the bike unrideable. It sounds like a two-stroke lawnmower engine that a squirrel crawled inside. Plugs look relatively clean when pulled, just a tiny bit of carbon buildup.
I read some bad reviews about Keyster kits, so I threw all the old jets and needles back in. No change.
Basically, I'm out of ideas, and give up! I want to send off my carbs to someone who can properly set them up for a CB360, (no modifications - stock mufflers and air filters) and make sure everything's good, beyond my level of carburetor expertise. Any help at all would be appreciated!
There she is, lookin' all sad sitting around all the time.
