Product Description
TB 114cc High Compression Big Bore Kit – Chinese 86cc – 107cc (49.5mm Stroke)
TBparts 114cc big bore kit will give your Chinese 90 or 110cc engine a big boost in power! Bolted on the 90cc engines, this bore kit alone can net you around 5hp depending on supporting modifications. On the 110cc engines its about a 20% increase or 1.5hp. If your looking for more power we also offer 2 high performance race heads, camshafts, and VM26 carburetor kits too! This is the same kit we run on the Honda TRX90s so we have years of experience running and tunning these! Bolt on big power to run with the larger 125cc engines!
Kit features:
- Lightweight aluminum cylinder with steel sleeve (huge weight savings over your stock cast iron cylinder)
- Cast in mounts on cylinder for aftermarket skid plates
- Oversized cooling fins on cylinder for efficient heat dissipation
- High compression lightweight 54mm piston with rings, pin, & clips (replaces your low compression dished or flat top piston, but still safe on 91-93 Octane Pump Gas)
- Head gasket kit
For use with these two Chinese engines – 86/90cc 47×49.5mm bore/stroke and 107/110cc 52.4×49.5mm bore/stroke.
