Rad. Thanks for the heads up broskis. I think I'm gonna swoop on the 103, dude wants more for it, but it's in overall better condition.
I think I'm gonna try to keep it pretty stockish and try to pull power out of it as I gain more experience. I put kits on my e50's and they blast pretty good for only having some light porting, but it seems like vario bikes offer a lot more return on investment (in terms of skill and effort involved at least).
A corrolary variator question: Is it possible to tune a PA50II with a stock cylinder to do 50 like a champ? I was talking to a guy with a TSA at a party the other week and he seemed pretty doubtful it could be done.
