Greetings from Philadelphia! New guy needs some help, (shocking!). Took my '81 cm 400 custom apart over the winter, got all the rust and pitting off, cleaned the carbs and replaced some gaskets, bike looks great, problem is it won't shift. I have the lifter piece and circlip in the right places, according to the manual, but i'm just getting nothing. The trans was strong before, shifting well and all, so I didn't take it apart, not sure what could be causing it.
