I ran the yamaha green with a 42/35 maxx roller and the HH spring in a piped and ported sx.

try a white or pink, green work good too...the other two have more side force

Mr Sled could you please explain what the stiffer springs will do,are we trying to ballance the secondary to the primary because of the heavy hitter primary spring?
Thanks Steve

back shift faster, hold the belt tighter, hold the shift back longer...hurt the top end slightly...

Run the stock red secondary spring at 80 degree wrap. Before you do this clean the surface with sandpaper & after a few runs see if belt is slipping in the secondary. If it is you need to tighten the secondary but I think you will be fine.
