Little backstory for the engine, ect. Sled was bought several years ago and had to have a new engine and topend put in at the dealer as a hole in the piston was found and ran terrible in reverse with backfiring, ect.
Been about 250 miles post fix or 5 years ago (with proper break in after repair).
Recently the engine has been acting weird in reverse. It'll start, run perfectly, go into reverse easily with no backfiring, but after a few minutes of running when you go to rev it in reverse itll bounce around at 3-4k or roughly right before the clutch kicks in and wont go any higher, yet itll do it just fine when cooled off. No issues when driving forward other then not wanting to start after being ran hard or for a long time. Compression reads at 110-107 at 8200 ft.
