Just a bit of info on the tiforce systems.The sumo system was removed and standard ti force pipework was fitted still with the 60mm can(race can).After mapping it picked up around 4 hp from 3500-6500 and only lost approx 1hp thru the topend.Sumo system felt like a 750 down low under 6000 rpm with stock bore and compression with yosh cams.Now its a nicer thing to ride.Still would prefer if the cams were advanced a little though.
