i was thinking about putting an rcr stage one kit on my boss...and i was wondering how much of a difference does this make on top end and acceleration ...thanks ..

 

It works out pretty good. You will notice a lot more acceleration and the jetting and airbox mod make a slight improvement on top speed. Over all for the money you can't beat it.

Any one installed an exhaust kit on TrailBoss yet?
Let me know which has the best HP increase.

 

I have an RCR stage 1 with low end pipe on order. i'll let you know how it helps when i get it installed.
