Where are you RMK guys finding the sweet spot for rpm? I have been playing with clutching and finding different results than a lot of aftermarket company's are claiming. They claim 8100 is best power, but my sled so far seems to run considerably better at 83-8400. Sled feels slow and tractorish when clutched for 8100. At 8400 track speed is significantly higher, and sled is getting on top of the snow and just feels much faster. Im currently using the SLP magnum force weights but not sure yet if I like them. Im planning to do a some more testing this week so I thought Id see where you guys are aiming.
My sled
19 850 155 2.6 just under 600mi
I weight 260 with gear, and always have 3 gal of fuel on tunnel (until end of day anyways:face-icon-small-hap)
Edit:
little more clarification on rpm. this is for rpm while track is fully buried in snow and motor loaded hard for long pulls. this is not track outa snow wheelie tach blipping to 8300 once in awhile. when I say im clutched for 83-8400 I will see 85-8550 at various times, but full pull she settles in and holds 83-8400. and vise versa, when im clutched for 8-8100 I will see 8300 on the tach, then settle and pull 8100.
