Have just bought an 04 sy125 which has been sitting in a barn the last 6years and the engine casings and cooling fins have marks on them ,the only way i can describe them is like a tarnish in places ,has anyone else had this problem and if so how to cure or do i just paint it ????

CHEERS

First put some fresh gas in it.

Then start it and warm it up.

Then ride it.

While you're riding, you'll never notice the cases.
