That's very interesting and thanks for the information. BUT...
I'm of the opinion that if I was'nt satisfied with my TTR's performance then it would be more worth my while to get a bike that WOULD fit my requirements, rather than spend money on something that MAY improve it.
Just my thought.
I have a "superbike" (GSF1200) that is plenty fast enough for me and I doubt if I've EVER used its full potential. It has a conservative 100bhp output. Now, I've seen many owners that have tweaked their engines for "improved" output BUT I doubt if they would be able to use their enhanced power, never mind being capabale of handling it!
Just my thoughts. Disregard them if you want to shell out on new cams when your original cams are still OK.
