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.
All of our
products listed for the Warrior will work for the new Raptor 350 (see
notes for cam differences).
