Not possible to move it even 1mm...
as I said everything is welded to the axle, hubs, spacers, sprocket/brake hub, locking collars at the bearings. The only way to move the axle is to unbolt the bearings from the hangers, and then the only movement you get is pulling the axle out through the bearing hanger bottom slots. No repositioning anything on the axle sadly, no sliding it over, nothing.
Basically where the bolt head is on the clutch lines up to the teeth on the axle sprocket. The only way I can think to get the teeth of both clutch and sprocket to line up is to move the engine toward the sprocket more. And the only way I can do that is to cut the plate mounting holes and widen then a bit.
I could slap about 4-5 more washers on the shaft for the clutch and get a longer bolt, but then the clutch would only be about 1/2 to 2/3 on the shaft, and I wasn't sure I'd that would be ok, or I'd it would hurt the clutch at all.
Would it be ok to have the clutch only about half way on the shaft, or would that be a big no no?
