Tuning –All year models will require tuning for the new larger engine displacement.

Case boring is required: If you don’t have any experience working on your engine, we highly recommend having a professional technician install this kit or, at a minimum, purchasing the shop manual for your bike available from your local Honda dealer. Case boring requires precision and it creates a ton of metal shavings. Its best to completely disassemble (split) the engine when you bore your cases. That way you can ensure the cases are 100% clean and ready for reassembly.

Cylinder skirt L x W is 27 x 60.4mm.

Note –This kits cylinder skirt is extended. This is for future use with a stroker crank in the future. Since the cylinder skirt extends down farther than OEM, when you clear material for the skirt you will remove material directly behind the oil pump. We have successfully cleared this part of the case for this larger cylinder out to 61mm for the 60.4mm wide skirt w/out any issue.
