Sure always happy to brag... I mean share.

Where do I $tart....

I'm running wiseco RM125 pistons, 56.0mm (+2.00mm over). These have single rings along with a substantial weight savings over stock.

Cylinder porting is similar to NF5 RS250; PJ38 carbs and coils from RS250; Boyesen high tension CF reeds (from CR125 application, PRO-01); HRC 010 card.

Cases have been cleaned up and filled in places; Tyga lightened MC28 flywheel; custom heads with inserts and center aligned spark plugs; JHa/custom pressurized airbox; Tyga mild-steel pipes with CF silencers.

To get the full 76hp, I have to use VP Racing U2 fuel. Very powerful but nasty, toxic stuff. The motor will make 73hp on AvGas. The dyno numbers are conservative/realistic as this same dyno usually reports 40-42bhp for RS125/TZ125 motors.

I have many dyno run sheets for this bike. But I do remember that installing those RS250 coils (used) and NSR250 plug wires (new) along with NGK B9ECM plugs was good for about 1.5hp.
