Well, that's not very pretty. Looks like it was a hair too tight. It would be interesting to see what the cylinder looks like all cleaned up. I think it will be usable.
There is no scratches in the piston or the cylinder. I'm just concerned obout all the blow by. Seems excessive for a cylinder without much time on it. I was wondering if the piston or cylinder is out of round.
The piston looks like it was verging on a multipoint type of siezeure. Like it was just barely making contact. I guess without a bore gauge checking for out of round is going to be impossible. How was the compression?
Lancourt. I hope it's just the ring. I'm bringing it to the bike shop tonight to get measure. I hope it can be fixed. My hope is it can be diamond honed to the proper spec.I cleaned up the cylinder and it mildly seized in 6 places. That's one bad thing about the kdx you just can't kill it I've been riding it for a year not knowing it looked like that. I sent an email to lancourt there said they would let a tech look at photos. I sure hope it can be fixed without having to wait another month for a replate.
It's hard to say there is several spots and I did not have anything to mark it with. I took it to the bike shop and with a telescopic gauge it seems to be fine. He is going to drop it by the machine shop just to make sure.and check piston clearance. Maybe I just cold seized it. I do let it warm up before I ride, but who knows.
