Trail Bikes - 143cc Race Head Upgrade Kit and or upgrade with 26mm Carb kit for KLX110 & DRZ110
Take your already ripping 143cc to the next level of performance

Key Features:

-28mm intake valve,
-23mm exhaust valve
-25mm intake port
-21mm exhaust port (valves come installed).

-Race Camshaft - now includes a cam with more lift and duration than the previous version.
-Head gasket kit - Now includes the cylinder head o-ring set and an exhaust gasket.
-Intake Kit for VM26 or other similar carbs (will match the race head better than intakes intended for the stock head - Not shown, but comes with rubber boot and mounting hardware)

This kit is an upgrade kit for anyone with a 143cc bore kit (TB or other brands).
It features a Zongchen brand Race Head that has larger valves and ports for increased performance over the stock head.
The Race Head adds a considerable amount of power to the KLXs or DRZs with a 143cc bore kit.
These are high quality parts and require no machining to the cases or other modifications - Just bolt on and go!

There are no installation instructions, but if you can replace your piston, swap out your rocker arms and install a camshaft, 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. Another option is purchasing the shop manual for your bike available from your local Kawasaki or Suzuki dealer. The parts are installed in the same manner as the OEM parts.
When Installing a new performance cylinder head or any cylinder head you MUST adjust the valves and tighten the tappet lock nuts. This should be common knowledge and is covered in all motorcycle shop manuals.

Exceeds OEM Standard equipment specification.
