How much of a power gain?

[07ERider]

My bike previously dyno'd 44.5 horse with a Rossier pipe, HRC cam, and the airbox lid removed with stock filter.

I just had Rossier do there "recreational" port job and I put in one of there custom 14:1 JE pistons. I also put on a K&N filter?

I am going to dyno it again here soon once I do some other little things, but I was curious what you guys think I might pick up with what I have done?

just a recreation port job and 14:1 on race fuel....hard to say but you will jump about 7-12 hp.

I will just be happy to break the 50 mark.

Prolly about 50.

I had a set up close to that and it was at 49 hp.
