brett and i have been working on my 85' puch maxi and although it goes 20 mph the worst problem is that it leak atf from the drain hole underneath. the threads were stripped out when we got it and it won't hold the proper bolt in tight. should we try to re-cut the threads or what? we're worried about getting metal shavings in the gear box if we do re-cut them. it pretty much drained itself over night and that sucks.
