How will my rpms be affected when going from a 46/40 stock cat helix to a 44/36 R or P? 09 Crossfire 800 141" 5-7000' elevation 75 gram cat weights, speedwerx H5 alloy springs with stock rates, bdx rock rollers, shift assist. 190 w/ gear. SLP pipe, 141" Pclaw 2.25. I was pulling 7800 MAX, but around 75-7600 average on my last trip. It would not back shift worth a crap. I stuck a new belt on and broke it in pretty well, but noticed i pulled a ratard move and put it on the wrong way, then fixed it after like 15 miles. Is this belt junk now? The sled has always ran great and the clutching felt good until this trip. Maybe there is something else wrong? The track was very very loose on this trip which may have been a problem? How many rpms will the helix change add?
