after some more research apparently this is a common problem. The rod you're supposed to adjust (turn) has a crap ton of loctite on it making it almost impossible to break free & adjust (my experience so far). Some owners suggest removing the foot peg assembly to get at the adjuster rod, remove the rosejoint and turn it to adjust the shift lever. Notes from posts:
"Take the footrest hanger off the bike and disconnect the bottom rosejoint and you'll be able to adjust it this way by rotating the whole rosejoint in/out as required, then put the whole thing back on the footrest hanger and re assemble"
"I've had the same issue too. You need to dismantle the gear-lever sufficient to remove it from the bike. Disconnect the quick-shifter wire at it's loom connection clip. Then you can rotate the whole thing to lengthen or shorten the rod as required. It takes a few trial refits before one can be fully content though. A special effort needs to be made with the adjustment with referance to the angle between the rod and the little actuating levers (one attached to the pedal end and the other one clamped to the splined shaft sticking out of the gear-box). However else you adjust things, the angle between rod and lever needs to be as close to 90 degrees as you can possibly get. If you don't follow this rule you will get missed gears and probably damage the gear-train.... so be warned Mr. Shed Expert !"
