i removed the cylinder off my 50 cc grubbe skyhawk last night after 400 miles of operation and noitced that the chrome was scratched off vertically in 2 separate location right where the ring end gaps meet up.
i ran 30:1 lucas 2 stroke oil the entire time, i this normal?
or was it getting hot, plug was a nice tan color for the last 200 miles.
