It seized while riding at the dunes. Rear tires just locked up. I pulled in the clutch and hit the started while still rolling and it fired back up so I kept riding. went about another 2 minutes wide open (rev limiter) in 3rd gear and it locked up tight. No grinding or funny racket. Just instantly stopped...

Took about 2 onths to get the crank out trying all different kinds of methods to break it free including ultrasound tanks and large hammers...

Thats close to how my moto siezed up at the dunes. I had to raise the idle that morning because it really low. About a half hour later it stalled going down a hill a couple times then restarted ok. 10 minutes later while full tilt in a big bowl it did the full screeching lockup and that was it. I had steel specs in the filter for 3 oil changes before so I knew something wasnt good. I love it when they blow chunks at full power. My speed dropped a valve 2 days later at max rpm in first gear climbing the steep sides choke cherry hill. Geared way to tall. What a week of destruction. :head:

maybe Ill keepit in my back up motor.

Where are you at Wisetech, I did Saint Anthonies in may. Already had blown up the dale in Florence so I didnt get a chance to kill it at St A's

Im in WI but we are making at least one pilgrimage to the dunes once a year. We were there in may for the ATK ride. ST Anthonies is all the hype and more. We hit little sahara for 2 days and then Anthonies for 3 . It was a little rainy and windy for one day so everybody left. Then we had the whole place to ourselves . All Virgin sand all day. :wow

man u just missed out i just sold a whole piston kit (cylinder, piston, rings, and misc) for $50. It was almost brand new, i only replaced it becuase i had the motor apart for stage 8 and while it was apart i decided to go a little further and put a cast iron cylinder and a WWE updated high comp piston. that little kit cost me $340. I wouldnt take any chances with that beat up piston, play it safe and replace it.
