:waving:Welcome and Hello . Can you offer more info on what you cant figure out . On the left side of the engine should be the shift shaft (below the head ). When the engine is in the frame it need to have the shifter extension mounted on the shifter shaft ( offset shaft which attaches to the shifter shaft ) . The reason for the offset is to clear the header pipes . I am not sure if any of that is what your asking about . If you can clear up the question I am sure some of us can offer more help . If you have repaired the gears Then I guess you have a service book of some brand ?
I am using a clymer manual. I removed the engine front cover because I could not get the shifter to work. The spinle arm will not pull back far enough to upshift using the shifter but when I do it manually I can get it to move. And there are only 4 pins in the cam plate but I have 5 gears.
Thanks for your replies.
