Message: [QUOTE="a454elk, post: 901707, member: 23609"] 01 RM here as well, but the difference is my rings failed the first time the top end went, causing the ring to go forward and catching on the exhaust port, down stroke, tore the top of the piston off. Caused major gauges in the cylinder wall so it had to be replated. Now, last week, about 20 hours of riding on it and the upper ring broke again, (Using stock rings and psiton again), this time a small portion of the piston broke off and I believe it went out the exhaust, same with the missing piece of ring. My powervalve has been a problem for about 2 years now. It tends to stick in the port and the last time it did that it broke the bottom portion of the powervalve actuator. I found that it is extremely important to keep the valve clean at all times. I don't think my valve is hitting the ring and piston, If so, it should have done it a long time ago. I think the ring fails and it moves out of it's seat, then it catches. Your jetting seems fine but the airscrew should be out 1 1/2 turns I believe. Check your reeds to make sure they aren't chipped or broken too. The up and down idle sounds like an air problem to me. Check your boot around the carb, engine side too. Spray some carb cleaner around while it's running to make sure it's not sucking in air. Also, if race gas was run for while and it wasn't cleaned out, your jets and passages could be plugged, mainly the slow jet, pilot ones, that affects idle and just off. Clean out the carb completely, and I mean COMPLETELY. Race gas, when sitting, gums up like no tomorow. The idle problem could be associated to a clogged jet as well. Sorry about the lengthy reply, hope it helps. Elk [/QUOTE]
