Final drive shaft

(1/2) > >>

Lkp:
Hi everyone..

I've got a f2 cases and an f1 final drive will this be ok to use?

K2-K6:
The F2 (and paired K7) both use a larger final drive bearing to, I think, all the other 750s. This because they use 630 chain size.

I don't think the F1 bearing will fit, can you try and compare the output shaft mounting to give more certainty?

neilg:
Because of the bigger bearing the engine sprocket is further away from the engine case by about 5mm, so chain alignment needs checking.

hairygit:
The 750F0, F1, F2 and K 7 all use the same bearings on the final drive shaft, but the shafts are different part numbers for the F2 and K7.
