Re: 1974 CB360 Revving on its own] - fixed, new issue: poor acceleration / hesitation
Thanks bud I try to do my best, but troubleshooting bikes on here, especially carb issues can pretty much be a big shot in the dark at best. Since I am not looking directly at the bike.
And I couldnt agree more, nothing wrong w a problematic bike. If you are willing to learn and spend the wrenching time.
I like working on my bike more than riding it. Thats why my poor 360 looks so jacked up...I just can't stop fucking w the poor thing.
This is the only bike I've ever had. I dont claim to be the expert...but after 4 years of keeping her on the road...I do know a thing or two about her.
Like you said if its got small cracks in the diaphragms...even the JBMs will be a huge improvement. The JBMs I had worked pretty well at first when new. Then once they got a year or so old, is when they started giving me more and MORE TROUBLE.
Also, I was thinking check the insulators (manifold boots) at the engine gasket. They can warp if overtightend and cause leaks at the gasket. I used a little smear of Hondabond on my gaskets. I may have an old pic.
And check to make sure the caps are flat enough when fit on the body that they seal good when the diaphragms are in there. I used a big flat file and big emory sander at work to Level them off to perfect fit.
;Dthe carb I used in the picture is an old scrap one I got from a kid on DTT. LOL, You should see the rest of the thing. I think his only tools were a pair of pliers and a chisel. : The linkage on the thing is completely bent, destroyed and fucked. As though he ripped em off his bike and threw them across the garage into a concrete wall, then ran em over w his lawn mower. But all the brass parts were good & thats what I was after. So I was able to get a pretty darn good deal.
Leak at insulator gasket to engine head, overtightend screws.
warped carb caps, I dont know it was leaking for sure. But I made sure it wouldnt cause a leak.
Just filed a little off carb bodies to get em flat.
And sanded down the caps. Not too much, just enough.

I guess a problematic first bike is good in the sense that you learn a shit TON... a different kind of TON... that's what this sites title means ... right? ;D
Also trek, how are those throttle plate screws treating ya?
