Had my 330R out in Glamis 2 weeks ago. Bike was running killer and I jetted it in a bit rich. Was leading the group on an epic 3+ hour dune after some hillshooting at China wall. Motor just lost compression and died. Piston and cylinder only have about 10 hours on them.
The first problem I see is that the inside o-ring disintegrated.:mellow:
The second problem is some cylinder scarring at 4-o'clock when sitting on the bike. Check out the scarring close up.
How bad does the cylinder look?
