-Description: Wicked Motorsports CNC Billet RZ350 Torque Head 1983-TO LAST YEAR YPVS RZ-350


BILLET TORQUE HEAD.WITH INTEGRATED THERMOSTAT LOCATION! THE ONLY ONE OF IT'S KIND TO HAVE THIS OPTION IN THE INDUSTRY! After working on engines for the past 20 years Wicked Motorsports decided to make the last after market head that would be needed in the 2-stroke YAMAHA RZ350 industry. For the 64-70mm bore size YFZ 350 Yamaha Banshee. Wicked Motorsports took all the aftermarket head flaws in the industry and developed the flawless 1 piece interchangeable dome head, Wicked Motorsports discovered the average head has air pockets causing hot spots in the combustion and Cylinder chamber. Wicked Motorsports eliminated that problem by chambering the flow pattern and having the coolant flow through all the chambers around the domes. This forces the coolant flow through the cylinder walls and through the dome area out the cylinder head. The end result a cooler running head and cylinder. As you read below Wicked Motorsports did not just stop there.


-POWER: Improves all around power band & increases horsepower. For great options to recess domes for +4mm,+7mm or +10mm stroker motors! (Depending on engine applications)


-ONE PIECE: One piece head with interchangeable domes to improve the strength and structure over the flimsy standard factory RZ350 head.


-HEAT: Dissipates heat from cylinder and head with proper flow patterns. As well has factory location built in thermostat location! Also creates higher contributions from prevention of cylinder detonation with our billet domes and angles.


-FEWER HEADACHES: Bolt on! Only requires 8-o-rings which stay in location while assembly with out falling out! -MINIMIZED: No cylinder stud changing required. You can use the factory studs with out having to remove them and. Bolt on design!
