How much power

[trent03z400]

I am installing a curtis sparks exhaust and a hrc cam on my 07 r. I was just wondering if anyone had any dynos of this. And knows how much hp and torque i should be getting. Thanks

Stock...you're at around 39hp...I'd say you are around 43hp or so with the HRC Cam and Spark exhaust. Thats just a guess tho haha :). And thats if you get the jetting right too :).

I'd recommend taking the airbox lid off as well.

Lift the main jet to 185 with the airbox lid off as well to benefit from the cam and pipe!
