I must say, you are one heck of a salesman!! Tough to resist that sort of temptation!

What were the failures? What did you change after each problem to prevent future problems?

Agreed, WB
Markmoto parts just don't fail, there is a chain of events that lead to a failure, it could be something as simple as a crank seal that is shot. The piston and cyl will tell you the entire story, you just have to know how to understand what they are telling you. Do you have a 4 corner scuff, melted piston crown, hole in the piston?
Post your piston pics man! If you want help.

what compression ratio are you running and at what alltitudes are you having the burndowns. if you burndown u should try to figure out why,not just put in new pistons and hope for the best. i personally wouldnt run anything higher than 13/1 on premium pump gas below 6000'. If you are serious about selling ill give you 1000 cnadian and take that sled off your hands with the blown up motor. pm me if u want to get rid of it.
