GS750 gear box to GS1000?

[wraith]

Has anybody used/put in a GS750 gear box in a GS1000 and if so was it a strate swop?
Is there any differance between the two gear boxes?
The reson I'm asking is I'm starting to build a GS1000 motor and I dont have a conplet GS100 gear box.

Cheers

The 8 valve 750 trans will work in the gs1000 but you must swap the shaft the sprocket for the drive chain goes on because the 1000 shaft is longer. The first three gears are lower on the 750 and should make it launch harder. Fourth and fifth are the same. I did this swap But have not finished the bike yet, so I cant say how it rides but it shifts fine.

Cheers for that, I thort I had a full gear box for te spair motor I'm going to build, but having a root about in the shed it seems like I only have harf a gear box.
If I can find a out put shaft I may have a look at the 750 box

Got a GS750 gear box (2v head type)but the gear coges seem to be the same size/number of teeth on all coges?
The shafts are a shorter lenth to the gs1000 but the coges will interchange.
The only diferance I can see is some of the gs750 coges seem to have more of a angel on the side ( I will get some pics tomorow)
I think the gs750 has a bit more of a under cut box than the 1000 so would be worth using it anyway.
