I'm full grown at 5'7" and about 135/140....
So I'm still small at my "full-grown height."
Do you still think that the 80'd be a bad idea considering it needs a lot of attention too....
And if the general description of "needs rebuilt" is exactly that for the 100, wouldn't it need just as much attention.
(Just asking questions, not questioning your wisdom or advice haha)
Yes, its still a bad idea. That is essentially a parts bike, and not a good one at that since many of the good parts are gone. I'd look for a 125 2-stroke at your height/weight.
yes, but the question is, do you want her to reproduce and make a bunch of little bitches? just sayin. holes in condom = not a good idea. 
that thread is down the hall to your left.
