Hiya, it kinda loses a little torque at the bottom end as I know have all the KIPS valves in place and its definitly got a little more bottom end with all the valves closed...I am currently fixing the actuater that drives the KIPS and opens them up, when that is done i will report back....
Nice to have all the bits done finally, took a while to get the parts...
But to sum it up i ran the bike with no vallevs at all (none of the two KIPS side valves or the main axhaust valve) and I used the bike quite happily for loads of rides...and it performed really well.
