In part 6 of our 2017 Yamaha Raptor engine build, we’ll show you how to install the valves in the engine. This process takes a little time and attention to detail, as John will show you how to check the valve’s contact with the valve openings and then show you how to lap the valves.
We’ll also show you how to install the camshaft on your Yamaha Raptor 700.
