Description
New OEM Yamaha head with the Kibblewhite Stainless Steel valve and spring converison kit from the original Titanium. We don’t suggest this conversion for race use. Reduces power by 10%, has a greater chance of floating a valve and doesn’t wear a lot better than titanium. Stainless valves are about 70% heavier than stock and require heavy duty springs. We do not guarantee stainless conversions. The good thing is that they are cheaper.
