Well here is me racing a trx450r that has a hot cam, factory portwork (whatever that is) K&N box filter, fmf factory 4.1 exhaust system, and +4 timing. My banshee has Pro Circuit pipes and silencers, Pod filters with outerwears, Boyesen Rad valves, carbon fiber reeds, modified shift star and runs on a mix of 1:3 110/97 octane mixed 40:1 with amsoil dominator. He pulled off the line every time but I took him in the top end 60% of the time.
Also when I hit one of the whoops I accidentally shifted into 4th and lost. (you can hear it boggin lol)
