so i went riding in millanockett maine this weekend, and my 01 edge x 600 would only do about 60mph at 6000 rpms in the loose wet snow. but if i got on bare ice it had no problem getting right up to 80-90 mph at 8000 rpms. the guy i bought it from said it had a clutch kit in it and a friend of mine said this problem wa due to the clutch being set up wrong or the wrong one for this motor. it has a yellow clutch spring. also when i first take off it has great power and revs right up to 7500 -8000 rpms.
