1. I am getting conflicting info.....will an aftermarket cylinder kit fit on a PA50I engine case (without machining the skirt)? Can I use the original head?

2. I am considering a 70cc upgrade to haul my 210lb ass. I am aware that i need to upgrade carb, inlet tube, exhaust, reed block, and variator. Any comments on specific kits would be helpful. I was thinking of drilling out the carb (1/2") and putting in a bigger jet.

3. Which exhaust should I use? I still want to operate the pedals and center stand. I also don't want it to sound like a loud chainsaw. Comments?
