I'm in the same boat. currently my mag does 41 top speed on stock gears. 70cc treats v1 kit - (i believe no porting - no case match - haven't opened it up), 15mm bing(76jet), stock crank, circuit pipe, dunno bout clutch, high flow air filter

got 17t front,40t and 36t rears coming from treats. i'd also like to top out at about that 50ish but fear the stock crank - so i'm trying to keep it at or under 9k rpm (16x36 is what i'm going to try first)
