[QUOTE="muddy226, post: 898266, member: 46421"] I may have missed some previous posts on this, but exactly the same thing happened to a new piston in my RM after having the cylinder re-plated, and was caused by the main powervalve protruding too far into the cylinder and snagging the top ring. The reason was that the powervalve is worn and has gone sloppy, allowing a side of it to protrude too far. I think that this excess wear was caused by cleaning the assembly with oven cleaner, which damaged the protective coating on the aluminium valve. A new one was quoted at £250.00, so the file was used. Its OK so far. I'd be interested to know what caused your piston to be damaged. Incidentally, my piston was also a Wiseco, but I think that that is just coincidence, as I put a Wiseco in again and no probs so far. I wasn't so lucky with the head, but I put it in the vice on a power drill and cleaned it as best as possible, which wasn't very good, but it seems to run pretty good. If anyone knows where I might get a replacement PV for reasonable money I'd be grateful ! [/QUOTE]
