In June my sons raptor 80 died. I found no compression, and upon disassembly I found the rings had frozen to the piston (the yamaha shop called it a carbon problem). I replaced the rings and scraped out the ring grooves, reassembled it and it ran great. Last weekend it died again (we are weekend warriors only so there wasn't allot of ride time between instances) , and upon disassembly I found the rings frozen to the piston again. Any Ideas out there?

Thanks
Rick
