@@kazantipa it depends on riding habits. In the mountain sleds, getting run hard and likely not maintained well, 6500K is probably time to rebuild. However I have seen trail sleds go 10K without a rebuild. The 600 will have a longer life as well. The key is to keep the crank greased, proper warm up and running good oil/fuel
I took the clutch off to check the isoflex grease as preventative maintenance, noticed the inside race of the putside PTO bearing was turning on the crank, just by hand. Not sure what caused it to wear like that
