## What it fits

The store lists a part under each bike or engine model it is meant for (the categories below) and may name models in the description. Do not assume it fits a bike or engine that is not named here; ask the store first.

Where a fitment line says "All", it means all years of the model named on that line, not all bikes.

## Description (the store's own text)

TBparts 60mm 143cc Big Bore Kit: An all aluminum ceramic coated cylinder. No case boring required, bolt on! 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). Lightweight, high compression 10.5:1 domed 60mm piston comes with rings, pin, & clips (will safely run on pump gas, 90-93 octane). Top end gaskets are also included.

Nibbi PE26 with TBparts manifold/carb kit: 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. Making them an AMAZING value overall! Paired with our large intake manifold for the stock head. This will give you some of the best throttle response and consistent reliable power on the market! We also include a low profile air filter and extended throttle cable for the KLX110.
