Did you rebuild after any piston/ring damage? Maybe there's still a bit of piston/ring, which could have been lurking in the crank but is now bouncing around in the combustion chamber
It does sound top end, rather than main bearings. |
I changed piston, rings. I did honing. I looked, head gasked is ok, piston isn't touching it. Plug was raised, and i kept it raised.
I rebuild it, because the compression was low. Everything else was in good condition.
I don't know what check. I looked at power valve, but it is ok.
What you can say about small end from video? Connecting rod is straight, just video is distorted. But I worry because bearing is moving sideways, and I don't know is this right?
I'm newbie at motorcycles  This is my first. |

What size piston? Did you check to see if the old one was oversized?
How many KM has the engine done?
I think you need to get the barrel or at least the head off to have a look. What ever the problem, you'll have to anyway.
