MOPED ARMY

I found out why my bike wont run.

Piston melted by the ring set pin. Scored and toasted the cylinder.

Oh well. Ordered 80cc Athena Reed kit

Way the kit is.

No way i'd run something like that .

Either use a different kit or change the pin location on that kit .

Who ever designed that had their head where the sun doesn't shine .

You sure that piston wasn't upside down? I've seen many kits, and the most basic thing from an engineering perspective when making a kit is to make sure the pin is not over a port.

i support the piston upside down assumption: i can almost convince myself i see the arrow on the piston head (which should point toward the exhaust) on the opposite side as that smear

Then put the piston in the cylinder bottom. Line up the cutouts in the cylinder skirt with the cutouts in the piston skirt . They should be an obvious match . That's how the piston should fit on the rod .

Mark the piston so you know which is the exhaust side . Maybe a scratch inside the piston skirt .
