TBParts 132cc Big Bore Kit with Stage 2.5 Camshaft – Honda CRF110

The largest bore you can run on a Honda CRF110 without boring the cases — and now paired with the TBParts Mini MX Stage 2.5 camshaft for even more power throughout the entire powerband. Whether you’re rebuilding a worn engine or chasing more performance, this bolt-on kit delivers real gains at an affordable price on all CRF110 year models.

132cc Big Bore Kit – Key Features

• Fits all Honda CRF110 year models
• Largest bore possible without case boring
• Bolt-on installation — tuning required for carbureted and fuel injected models
• Cylinder includes temperature sensor port for 2019+ fuel injected models
• Runs on 91+ octane pump fuel

TBParts Stage 2.5 Camshaft – Mini MX

• High performance Stage 2.5 cam designed for Mini MX racing
• Compatible with stock engines, 132cc, and 147cc big bore kits
• Valve lash settings at TDC: 0.003″ intake & exhaust

Important Notes

• When using TBParts 132cc piston (TBW0892), the supplied 1.5mm thick base gasket must be used unless the TBW0888 Big Valve Kit is installed — it reduces compression to prevent engine knock
• 2019+ fuel injected CRF110 models require an ECU flash/tune to prevent a lean condition. CJR Performance provides this service and can tune for additional modifications
