TBparts V2 Race Head: Starting with the addition of forged aluminum roller rocker arms and our V2-2 camshaft. Not only do the aluminum roller rockers free up big horsepower, but you can also run much more aggressive cam profiles with roller rockers for even more power. Next is the bigger valves 30mm intake and 24.5mm Exhaust. The intake and exhaust ports are equally as improved at 27/23mm. Both valves are stainless steel too (21-4N material). The valves also come installed, complete with high lift heavy duty valve springs.

Case splitting required: If you don’t have experience working on your engine, we highly recommend having a professional technician install this kit or, at a minimum, purchasing the shop manual for your bike available from your local Kawasaki or Suzuki dealer. Installing a crankshaft requires delicate technique.

Note 1 – If you have an 07 or older model with the original OEM Output Shaft we highly recommend also purchasing our strengthened Output Shaft available in this section.  The 02 thru 07 Output Shafts were very weak and would often snap. They have a oil hole drilled straight through the shaft at the opposite end of the sprocket, so best to update while you have the engine apart.

Note 2 – We also recommend our heavy duty clutch plate kit TBW1035, for best results convert to full manual.

Tuning Required

Note: Make sure the air fuel screw is 1.5 turns out from bottom before you start tuning.

There are no installation instructions, but if you can replace your piston, you can install this kit.
