That''s a good idea, I remember Aussie Dave telling me he was making more power with his Suzuki builds vs. Yosh at one point. He compared when he bought a Yosh motor from them. I was surprised and asked why? He said he could take more chances on failure than they could and pushed it more. So, I think he will shoot you straight and probably give you a very cost effective option.
It’s so funny as what Robby said. Everyone thinks Harley. They do heads for some of the winning bikes overseas as well. Last time I was over had 4 in my carry on :/)
Has anyone mentioned Jason Farrell? He knows Kawi motors pretty well. http://www.farrellperformance.com/
I built the motors, they did the headwork and I have a special grind cam we made up. As far as power, enough to run up front and lead several miles. We got between 2-4 Hp bump depending on the cam and tuning depending on the track.
Also, and if he can't do it he'll direct you in what he believes is the best direction, Mat Drucker at MD Racing. He used to be on here but last time I saw him on here was during the Cory West BMC/Daytona/2nd filter on the grassy knoll era.
