What is the best way to get the M/C to back shift. I have a 03.5 900 with a can and reeds, and a 162-2.5 track. the set up a lot of guys are running around here is a 60/52 helix with a green sno-pro spring, but I don't have good back shift. any thoughts? I'm running 70.5 weights
do I get more back shift with a tighter secondary spring?
