High Compression Performance Kit for Yamaha Bolt

Description

A kit of three components to produce high compression ratio and performance on the Yamaha Bolt and XV950 model engines. This is only sold at MDU and we include the following components:

• • Wiseco Piston Kit – includes two pistons and needed rings, circlips, and wrist pins
  • Webcam Racing Cams Performance Cam Set – includes two performance cams and needed pins with optimized lift and duration
  • R/D Valve Spring Kit – includes all eight springs and top retainers to replace the weak OEM valve springs

Putting all these components together utilizes and increases the bike from the stock ratio of 9.0:1 to a 10.5:1 ratio. We will be providing a time card, dyno sheet, and other details for this once we have it installed on our test bike. For those that wish to get started sooner than later we offer the kit ready for sale.
