Well bought used moped that needs work.I know it's 49cc from the vin but I got some numbers on rear housing above rear brakes.it's 6b 7avico.05nfg.now what are these meaning?also it had no carb so heads are pretty dirty so figured in just replace them with one from a big bore kit just not sure which one is best.any help would be appreciated

Give it a read.

I went with the 52mm but it is said you'll end up wearing out the bottom end if you beat it like a rented mule.

I am one of those ride it like you stole it so I did minimal break in and whooped on it ever since. Wasn't uncommon to do a 70 mile country ride pinned most of the time

I have had zero issues since doing mine but we'll see what next season brings.

I didn't do the head because after getting it open I found it wasn't actually a 49 cc
I didn't measure it but I'm guessing stock it was 44mm so figured it was good enough for now.

I just wanted to get 50mph and more power up hills/off the light, I got that so left it alone.
