Powroll - 4 Stroke Performance
 
 

 

Powroll Products for the Yamaha Raptor 350

STOCK SPECIFICATIONS:   

83mm BORE X 64.5mm STROKE  9.2:1 COMPRESSION

FYI:  In 2004, Yamaha released the Raptor 350.  Utilizing the Warrior engine and chassis, Yamaha did some work on the frame geometry and added goodies like the YFZ450 footpegs to make the new Raptor a better handing and easier riding machine.  All the internal components are pretty much the same as the Warrior, with the exception of the OEM camshaft and headpipe.  The Raptor header was designed to increase torque and midrange over the earlier Warrior design.
