Description
The Athena Yamaha Zuma 70cc performance cylinder kit is made from cast aluminum with a nickel carbide-plated bore to ensure long-lasting performance for your Zuma 50. As a long-time provider in aftermarket performance parts, Athena is a great choice for your big bore kit. They’ve been developing gaskets and crankshafts for some time, making their products unrivaled by most other companies. This Big Bore for the 1997-2001 Yamaha Zuma 50 2-Stroke will require a few modifications for a better running vehicle. This includes manual premixing your gas and oil and also upgrading your carburetor. We always pair our cylinder kits with larger carburetors to allow for a more rich tune to keep down the heat and provide the best performance. This keeps it more reliable while still powerful!
