All year models will require tuning for the new larger engine displacement and camshaft. For the 2019 and up fuel injected models, the ECU will require a flash/tune to prevent a lean condition and possible damage to your engine.

Com) provides this service and can also adjust the tune based on your other modifications. 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 the engine when you bore a set of cases.

That way you can ensure the cases are 100% clean for reassembly. Cylinder skirt L x W is 27 x 60.4mm. Note - Our cylinder skirt is extended. This is for future use with a stroker crank we are working on bringing to production. 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 successful clearance this part of the case for the new larger cylinder out to 61mm for the 60.4mm wide skirt without any issue. Have any questions or concerns?
