FYI: Although externally similar
to the Z50, the Honda XR and CRF 50 internals are significantly different from the
Z50. No performance parts are readily interchangeable.
Chinese
and Taiwanese engines which are 'like Honda' design are not copies of the CRF or
XR. These engines share similarities to a variety of Honda engine designs,
but aren't the same as any ONE Honda engine.

This Billet cap produces more power by allowing the engine to vent
excess crankcase pressure.
Reducing crankcase pressure will allow your engine to rev higher and
pull harder! Installs in place of the stock intake valve
cover.
Choose Gold, Blue, Red or Silver. |
