Mr. Hamp- I'm new to the forums and I just got a new RMZ-450 and was looking into your TUF Racing and was wondering why they don't do anything with Suzuki's? Any plans to? One thing I have not been happy about is the notchy shifting on my RMZ? I did go to TUF's website and watched your tips and I am interested in the Bazzaz, but were do you go to learn how to use them or find the best fuel air ratio's? I heard if you buy a FMF full exhaust they supply you with one is that true? I would like to learn how to tune the fuel injection like I learned how to jet a carb! Where can I do this?
