2016 Yamaha YZ250X Cylinder Porting / Head Mod / Valve Mod

With the help of Triangle Cycles we got the spec dialed in for the 2016 YZ250X.  Send us your Cylinder, head and Center Valve and we will mod it out to use 110 octane race fuel, the stock piston and gaskets.  The end result is a bottom and mid that pulls like a four-stroke and a top end that does not shut off.  It will pull those taller gears no problem.  You get the best of both worlds for just $250.
