Hello I'm a Puch newb. I just bought a 1985 Puch Maxi for $100 in running condition just rolled 700 miles. I would like to add a big bore kit and with the information that I have gathered from this forum if I get the 65cc Metrakit I will NOT have to upgrade the carb, intake, or exhaust. I did a extensive search in this forum and did not fix and concrete answer so please don't tell me to just search. I am willing to spend a little bit of money since this will be a "daily" driver when I'm down at college so any other suggestions are appreciated. I already tightened the exhaust belt and filled the blinker fluid ;)
