749 Swinging arm in M750

Having recently purchased a M750 I have now completely stripped the bike to its component parts in readiness for a complete rebuild including some modern extras.

One of these updates is to fit a 749 swinging arm and suspension to the bike, now I am not unfamiliar to fitting things that are not meant to fit and my plan is to keep the forum updated for those of you who are interested in this sort of thing.

The to do list so far and a few pictures.

1, Machine casings to accept 749 swinging arm
2, Chain alignment is slightly out and this can be overcome by using the bush/spigot I made in the pictures or fitting the later output shaft which is longer
3, Re locate and adapt the frame suspension mount
4, Replace crank casing needle roller bearings with solid bushes as the bearings will be in the swinging arm.
5, The rear wheel alignment is fine but there are number of spacer/bearing and caliper mounting issues to overcome.

Crankcases machined today and the swinging arm fits beautifully.

Looking forward to how this turns out!

Is there an alteration in wheelbase length?

Haven't got that far as the new forks have not arrived yet Frank butbetween centers on the monster swing arm is 19 1/2 inch where as the 749 is 19 inch

Suspension mounting needs a bit of fiddling as the top cross bar if you will needed to be removed and re located higher up the frame also one of the mounting eyes needed to be moved. Slowly coming together though.

Slowly coming together but everything seems to be in place and ready for some welding.

Engine painting and reassembly coming together
Bearings, rings checked along with new crank shells and bolts should be sweet.

All the parts back from Triple S powder coating so reassembly can begin.
