143cc Race Head V2, Big Bore Kit, and Intake Kit Contains the following:
This kit is the same as the complete kit minus the carburetor, throttle cable, and air filter. It does include the Intake Kit that port matches the V2 head and allows you to run the following boot/spigot mount type carbs:
Our TBW0321 throttle cable will work with most of the above carbs. For the air filter, a 42mm or 49mm mount filter will work depending on the carb uséd and we have both types available in this section.
Features of this kit:
It includes our Race Head V2, camshaft, and a larger intake manifold. While this head may appear to be the same on the outside as our previous (discontinued) race head and stock heads, internally it’s has numerous differences. The addition of forged aluminum roller rocker arms and a new camshaft are the biggest changes followed by bigger valves and ports. The exhaust valve (like the intake valve) is now stainless steel too (21-4N material). This all adds up to a cylinder head that puts out a professional level of performance yet is still affordable. The kit also includes an all aluminum ceramic coated cylinder. This cylinder is lighter than a steel sleeved aluminum cylinder, reduces friction (increasing power), improves sealing, and provides better heat transfer (runs and cools down quicker). In 2020 we upgraded the piston for higher compression and more power. Unlike other kits, our head gasket kit also includes a head o-ring set and exhaust gasket so you don’t have to re-use your old ones or make a trip to your local dealer to get new ones and spend more money. These are high quality parts and require no machining to the cases or other modifications – bolt on and go!
Add a stroker crankshaft for even more power!
There are no installation instructions, but if you can replace your piston, you can install this kit. If you don’t have any 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.
