Happy new years!!
Is it possible to put an 78' gearbox into an earlier 75' motor? (Both 447 motors) I know that Yamaha changed the shape of the gears for the box in 78' but will they match up with the crank and clutch on the 75'?
I have the chance of a cheap gearbox that's in good order and I'm wanting to install the overdrive 5th gear by swapping the gearboxes in the next rebuild.....
