Engine rebuild....am I just being thick?

[Jinxy]

Why can't I get the gear selector forks aligned with the gear shafts when putting the crankcase halves back together? Is there a trick I'm missing? Some bit of common sense I'm not party to? Or am I just being bloody thick?

Crank and gear shafts into top case, necessary studs in place, crank thrust bearings in place, O-rings in place....but lower the bottom half on and the forks just seem to go where they please.

Any advice?

1992 GSXR1127 lump btw.

patience...and a long thin screwdriver to move the gears sideways slightly if need be

Patience is starting to run thin. Christ knows how many times I've lifted the bottom case to make minute adjustments....or bloody big ones....but yeah, didn't think about using a long thin tool to do it with rather than fingers. Thanks.

put it into first gear this holds the two outside selector forks in place then long screwdriver to keep the middle selector fork in place, then when cases are together don't forget to try the gears to make sure they all work.

If your 1100 based engine is anything like my 86 750, you could put the motor together with the shift forks and drum left out. I've changed my drum and forks with the engine IN the frame. The drum and shift fork shaft will go in on the clutch side, while the forks can be put in from the bottom with the pan removed. Not super easy, but far from hard.
