PERFORMANCE MODS

Cylinder Porting
A performance mod for your trials machine which increases torque throughout the entire RPM range, giving your engine smoother response, more grunt, and better top end. Combine with our cylinder head mod for the ultimate trials engine!

Cylinder Head Mod
Your cylinder head is re-machined to a new combustion chamber shape and compression ratio. This gives you more torque throughout the entire RPM range.

Reed Cage Mod

Your stock reed cage is modified for more flow. Combined with our Boyesen Reeds, this mod gives a broader, smoother power band. Don't forget your spacer kit!
