Far exceeded my expectations!!
But like anything your experience will be what you make of it. Keep on top of the basic sled maintenance and you will be happy.
4 years and running strong. After the first two years I put in a new set of pistons as a P.M. and the old ones looked great!! The ring end gap measured to stock spec's even....
I think mixing the gas and oil is great because as boost increases fuel, the oil/fuel ratio's are always perfect and not held hostage by the oil injection pump.
Recommended setting on the fuel controller have been spot on and so has the clutching.
12 pounds of boost all day every day, M 1000 reeds, 70 AV/30 Pump , Stop and re start sled after large elevation changes and you have a pull rope, set it and forget it sled..... Any glitches within those parameters and it will always be minor sled maintenance (poor belt deflection, clutching, etc. ) due to riding the heck out of your sled.
