Maybe this is a good way to tell 48cc from 66cc, cause all the 66cc motors I have seen have had much larger studs and nuts on the head than the intake/exhaust (13mm or 14mm vs 10mm). I am still having a hard time believing the head studs and the intake/exhaust studs are the same size on even a 48cc, but you've got the wrench there and the motor to fit it on so I guess I have to trust you on that one. You can trust that what I am saying about the 2010/2011 Grubee 66cc is correct, the head studs and nuts are larger than the intake/exhaust...
I took a size 10 socket to confirm and it is a size 10.

It could be that the going up a hill puts the carb on an angle that makes it hard to run, you might be able to adjust the float in the carb a bit to eleviate that problem and make it run better when on an angle going up a hill if that is the case.
It loses speed. i think its ust because im too heavy and the hill is not that steep but the weight factor. Thats why I asked how to make these suckers go faster so I can zooom fast from the bottom and maybe with a multi speed bike I can down shift at the same time (if you can downshift). Overall its a fun bike I never thought Id go back into my childhood years and have fun with these things.
