Notes

New cylinder head for 09 with different porting and valve seats.

Rear spring losses free height quickly.

23.5mm offset triple clamps for 2009. Best results are with 22mm offset clamps. Rear spring rate selection and sag heights are crucial, 100mm sag must kept.

Rear shock stock setting does not have enough rebound dampening for many riders, same setting as 2008. Needs a pipe. Stock 12 tooth front sprocket wears chain guides.

42 Pilot can be used at altitude.

Convert engine to wet sump if clutch life is short. Needs a pipe.

20mm offset is standard on the 2 way adjustable clamps. Fork and shock settings are too stiff for most riders, hence the clicker settings.
