Frequently Asked Questions

Q: Is this kit compatible with Fuel Injected (TPI/i) models?
A: Yes, this kit is specifically designed to support both carbureted and TPI/i models as specified in the fitment guide.

Q: Should I perform a top-end refresh only or a full rebuild?
A: If your machine has high hours, replacing the crankshaft and all transmission bearings found in this kit is the only way to ensure factory-level reliability and eliminate hidden wear.

Expert Pro-Tip: When rebuilding, cleanliness is your best friend. Use a dedicated engine assembly lube on all bearings and the crankshaft journals. Ensure your power valve mechanism is cleaned of all carbon build-up during this process to ensure snappy, responsive performance after reassembly.
