Hi folks first time here. I have a 78 Ct90 . I got it running last summer and it ran fine randomly it started not starting. I wanted to rebuild the engine so I figured this was as good a time as ever to do it. So over the winter I have rebuilt the engine. I put in a dratv big bore kit, beyond that everything is stock. I put the engine back in the bike today and got it to start up finally. My joy was quickly dashed when i put the shifter on and tried to shift the engine. No movement in the shifter. So I took apart the right side of the engine and best I could tell was the gearshift arm wasn't properly engine with the drum. Almost as though there wasn't enough tension on the springs on the gear shift arm. Once I thought I got it to engage correctly, it would get hung up between gears. I thought this may have been because the engine was not running. so I reassembled got the bike started up and again no movement just like before I took it apart again. I don't think it is anything in the inner case as a can take a screwdriver on the bolt on the star shaped plate and turn through the gears without any issues. I also have that bolt nice a tight with loctite in place. I didn't take any pictures or videos while I had it open but can sometime this week. In the mean time are there any suggestions as to what I should look for.
