The sprocket hub shouldn’t be a problem.  I just did the same on a CRG for a friend.  And there will be a small gap on each side… this is normal.  Two things that I do with the 35 sprockets…

1. Ensure that you have both halves facing the “same” direction.  Most split sprockets will have a line to indicate which side of the two halves belong together.  Those lines should line up with each other when mounted.  If you put one half on the wrong way, it won’t line up properly and the chain will jump, bind, etc.

2. After ensuring the above, start tightening the nuts while leaving some play.  Then shove the motor mount forward  to take up the slack in the chain.  Then spin the axle – this will help “gap” the two halves properly.  Then fully tighten the nuts and bolts.  Finally, tighten the mount with the appropriate level of slack in the chain.  Spin axle to test it.  If you don’t do this, you will often have no gap on one side and a big gap on the other… chain binds, jumps, etc.
