G3 GSR tranny is hydro. G2 is cable so you will need a conversion kit and convert everything.

So no, UNLESS you get the hard to find YS1 GSR tranny. This is the tranny that came with the G2 GSRs. Hard to find and make sure you dont get the LS version of the YS1.

Easier to go with the G3 GSR tranny, but cheaper to get the YS1...
