you said the most you were getting was about 110 right? i was going to put a picco 45 with a tunned pipe which should push it aroud there but my ultra sport does about that same speed and i just want something faster.. hopefully a 90 would do it but the tower 75 setup isnt a bad idea but i was doing some test on the g3 just for rough rpm figures and the 12 -10 3 blade on the os 90 really cranks.
