We offer Kawasaki cylinder Big Bore kits 331 and 351; these kits also fit the current EFI models, the KLX 300.

This Dyno Run was with a 351 kit stock carb and stock exhaust.
This is a KLX 351 Big Bore Kit, which gives you more torque and horsepower over your stock KLX 250.


In all our Kawasaki kits, you will receive newly-bored cylinder with a new 300 sleeve installed, one set of gaskets (1 base & 1 head), piston, pin, rings, and 2 circlips. I only accept Pay Pal and Money Orders.
