ok i've got a z400 and it's no longer fast to me. the new wore off i guess...anyways i was thinking of some performance mods to open her up a little more.I'm really interested in the trinity kit....(exhaust,intake,and jet kit) what do you guys think of this? will i see massive improvement? if so where will it stand out against a stock z?

 

Free'ing up your exhaust and intake would help but cams ,high compression piston, big bore/stroker kit with porting would really wake that sleeping beauty.[img]i/expressions/face-icon-small-happy.gif[/img]
