I'm really impressed with the ported manifold that I got from Curt. As JD said noticed it in the butt dyno!!

You have a FI bike. I'm not sure what is available for it. It is a completely different intake than the carbed bikes.

Re:ported manifold 2 Years, 11 Months ago  
They say that you gain 4 to 6 HP but that up to debate IMO and beside they arn't my manifold. Mine are only tested on my bike on a Dyno and with a stock carb jetted properly, my ported manifold and a dyna 3000 it put out 75HP 98Lbs Tq and hit 130 mph on the dyno. The TQ was down because of short pipes a 2 in 1 would have given 100+Tq. I am not say the manifold will give you those number without the other components but you can feel it.

Re:ported manifold 2 Years, 11 Months ago  
Just saw what dave posted and my manifold won't help you. I do know some one went to some 42mm intake but then you have to go to larger injectors and a larger throttle body and it just isn't worth the cost plus you may have to have the heads ported to match the manifold. That is BIG $$$$.
