Thanks Richie look forwars to seeing what you do to your series one! Ive been looking around at what people have done to the st170 and im leaning towards GSXr/hayabusa throttle boddies running with mega jolt/squirt management... The only thing i dunno what to do about it wheather to keep vvt or not? Heard engine power is limited to around 200bhp... Do you know what is best route to take?? Cheers
