Trouble With Shifting From 1st to 2nd & 2nd to 1st

[wiredgeorge_imp]

Shifter causes shift pawls to grab pins in shift drum. This rotates drum and that is what changes gears. The rod between shifter and splined shaft that rotates and works shift pawls is only adjustment point. As has been pointed out, rod is threaded and has locknuts (M6) on both ends with one having left handed thread. Try to loosen both with 10mm open end wrench and back off nut that loosens. Also back off other nut turning clockwise. Normally one side is used for adjustment. Wrap a piece of old inner tube around threaded rod and turn rod about 1.5 turns and check shifter function. You may have to play with adjustment but no more than about two full turns from where you started. Blue Loctite nuts when you are adjusted and are snugging them down.
