79 390CR Trans Issues

Hi Guys,
Just finished assembling my 390CR. Complete restoration, new just about everything.
Put oil and gas in it and was getting ready to ifre it up, when I realoxed it won't shift?
Shift lever moves up and down like you would expect, but it won't grab a gear.
Tried rolling it around but no difference.
I put the trans together in 4th gear with 1 tooth on one side and 2 on the other like the picture in the manual. Side cover went right on and engaged the shift shaft.
I know I have to split the cases again, but what did I miss?
Appreciate any help.
Thanks, Ron

Hell,it's too pretty to ride anyway.Sounds like the shifting gear plate isn't engaged with the drum.Always check your shifting after you close up your cases.

It's kind of a frankenbike, but it was built to ride.
81 swingarm, piggyback Ohlins, 40mm forks and 18" an backwheel.
I'm pretty sure the gear plate is engaged.
That's the plate that the shift shaft goes thru right.
I don't think the cases would go together, if it wasn't in place.
That's the plate that has to be installed in 4th gear with the teeth visible on either side of the drum, to make sure you get all 6 speeds.
At least, that's the way I understood the manual.
I'm thinking I might get it to move with the side cover off, using a cresent wrench on the shift shaft.
Maybe I got a little burr in there somehow.

Very very nice, except the front fender which is not original (84+)!

Maybe the shifting dog fell out of place.It might be hard to determine the problem.When you open the cases those parts tend to move out of postion.
