This is the Replacement Crankshaft for the OS MAX .12CV-R Engine.|
Crankshaft is 1mm larger in diameter, increased from 9 to 10mm. This
allows for a larger crank port feed and smoother mixture flow ONLY
on the CV-R version.
This is the standard (long) shaft, however it can also be used for
the .12CV-R (S) short shaft engine but will have to be cut
down for short shaft application.
This crankshaft WILL NOT work with the Standard CV engine because
it is larger and machined differently.
