I have a 2017 800 axys 155 rmk with a slp stage 2. I had mtx weights and blue/red slp spring setup for 3000’-6000’ (68 gram base with 3 gram rivet in heel. 1 gram rivet in tip). I was hitting 8400 consistently and 8500 on setup snow, i switched to magnum force weights (40-150 kit) and i cannot pull more than 8200 rpm even when i remove set screws. I started out with 5 screws and a lock screw, i dropped to 3 set screws and a lock with minimal rpm change. most of the time im around 7950-8100 rpm whereas with the mtx weights id be 8350-8500. I switched weights while i was on the hill to see if the it was a motor mount/belt/power issue, rpm came back to 8350-8500, Is there anything else i should check? Belt deflection was polaris spec (1.25”) it has a Stock 40 helix and black spring in the secondary
