TB 143cc, 165cc, & 178 Race Head V2 & Intake Upgrade Kit
– Race Head V2 – Roller rockers, 30mm intake valve, 24.5mm exhaust valve,
27mm intake port, 23mm exhaust port (valves installed).
– Race Camshaft V2-1 for Race Head V2 (we can switch to our V2-2 if preferred,
just email after your order is placed and request the change)
– Race Head V2 Intake Kit
This kit only includes our new Race Head V2, camshaft, and
larger intake kit (see Important Notes below). While the new head may
appear to be the same on the outside as our other KLX110 type race head,
internally it has gone through numerous changes. The addition of forged aluminum roller
rocker arms and a new camshaft are the biggest changes followed by bigger valves
and ports. Both valves are now stainless as well (21-4N material).
This all adds up to a cylinder head that puts out a professional level of
performance yet is still affordable for the privateer rider. These are high quality
parts and require no machining to the cases or other modifications – bolt on
Important Note 1: If you have a 2010 or newer KLX110, you will also need our TBW0645 cam sprocket that is available in this section.
Important Note 2: This kit does not contain a piston.
You will need to either use one of our newly modified pistons or check your your
clearances very carefully and modify your piston’s reliefs to clear the bigger
valves, if need be. This head will not work with any of our
KLX big bore pistons sold prior to 3/18/08. We recommend getting one of our
kits in this section that includes the piston and a gasket kit.
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 in this
section or from
your local Kawasaki or Suzuki dealer. The parts are installed in the same manner as the
