This bore kit combo will make your KLX140 a lot more fun to ride by adding some much needed power! Our cam opens the valves up faster and provides more lift to let even more air and fuel in for even more power! Great for playbike racing and idles low enough to use on the trails too! TBparts PE26 carb kit for Kawasaki KLX140. CNC billet aluminum intake manifold, hard anodized black with the TBparts logo. Port matched for the stock head and made for use with the PE26 carb. The bike will pick up power everywhere! This manifold kit does not reuse the stock airbox/tube. Ideal for KLX140s equipped with a big bore kit and or stroker crank! Nibbi PE26 Carburetor. Nibbi helped perfect the simple design of the PE26! Starting with looks, they come hard anodized black. This helps with corrosion resistance, wear resistance, insulation, heat resistance and hardness/strength of the carburetor. The air passage starts out anodized then transitions into a smooth polished finished for optimal power and smooth consistent power. The lightweight hardware is also anodized. Another huge benefit is the splash guard. It keeps the engine operating smooth under bumpy riding.
