Wow. Thats unreal. Im rebuilding a 07 ptek 860 RKTek right now. The 860 done up right can be pretty hard on the cranks. This one has only about 1000 miles on it and the runout is 10-12 thou on a brand new installed crank. It’s turning a 156x3” track so its working.... hard.

Yes, I have never seen one grenade that badly before. I could understand it if he was full power making a climb or something. All he did was start it after helping out with a stuck sled to move it out of the way. Grabbed some throttle carved out of the way and bang, rattle rattle. Moved about 10 meters from starting point.

Screw JB, couple rags soaked in Seal-All will cure that bottom end. Save the JB for reshaping the ports for more PAH
