TB 143cc Big Bore Kit & Stg 1 Race Head V2 for KLX110 02-09. Includes our Race Head V2, Stage 1 camshaft, and 143cc bore kit. While this head may appear to be the same on the outside internally it’s has numerous differences.  First our V2 race head includes forged aluminum roller rocker arms and a new roller camshaft. 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!

Key Features:

• Race Head V2 – Forged Aluminum Roller Rockers, 30mm intake valve, 24.5mm exhaust valve, 27mm intake port, 23mm exhaust port (valves installed).
• Race Camshaft Stage 1 for Race Head V2 – Great for low end torque paired with 143cc setups
• Ceramic coated all aluminum cylinder (no steel sleeve)
• Lightweight high compression domed 60mm piston with rings, pin, & clips
• Head gasket kit – includes the cylinder head o-ring set and an exhaust gasket.

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.
