I ran them on my M1000, and on wife's M8. Might have been one of the best modifications to the sled, the compression secondary is junk. Belt life 8-900 miles on the M1K, Sold my wife's M8 with 1200 miles, still had the factory belt on it...all mountain riding.
Sounds like I should quit being lazy and install it on sled. Quick question does it affect alignment? Should I check alignment after I install the rk tek torsional secondary? Thank you
