I have a Yamme 2000 175 vmax and would like to try something out slow. How much would a Ht Flywheel help? is there a big rpm change i no the hole shot should be better but i have a good hole shot already. Is there somthing else i can put on for starters with out buying a hole fhase kit? What is good for mid and top end? O Yea!! It's on a 2000 1950 super Hawk 24 fury GPS 64-65 5400 rpms.
