Important Fitment Check
Before ordering, compare the original cylinder casting, oil-temperature sensor port, cylinder-base spigot, mounting-stud layout, head-gasket profile, 50 mm piston and 13 mm piston pin with the product photographs.
Honda used several cylinder revisions within the 110 cc engine family. The common KWB, K03 and KYK cylinder numbers listed above identify the same standard-bore engine family but vary by year and market.
This listing is not for the 55 mm / 132 cc big-bore kit. It is also not being advertised for carbureted applications where the cylinder sensor port would need to be plugged or adapted.
When This Kit May Be Required
- Low compression
- Scored or worn cylinder bore
- Piston seizure
- Broken or worn piston rings
- Excessive oil consumption
- Top-end engine overhaul
Installation
Correct piston orientation, piston-ring positioning, circlip installation, cam timing, valve clearances and gasket preparation are essential. Inspect the connecting rod, crankshaft, cam chain and oil-temperature sensor during the rebuild. Professional installation is recommended.
