YFZ450 6mm Kit w/ Cylinder

This kit will convert your YFZ-450 to a 513cc powerhouse.  This third generation kit is the best combination of power and durability.  Rather than bore out a stock cylinder, we use a completely new casting with heavier walls and larger water jackets.  This Tall Cylinder works with the 6mm  Billet Crank, but it doesn't need a spacer plate - the best of both worlds.

Includes:

"Clawhammer" 6mm Billet Stroker Crank 68mm
Falicon Knife Rod - Long
Tall Cast Cylinder- 98mm
Piston Kit (98mm) Stroker Compression
Wide Heavy Duty Cam Chain
Adjustable Cam Sprocket
Shorter Top Motor Mount
Oil Line Extension kit
Longer Head Bolts (4)
