got a 2 month old Gas Gas racing and the gold paint on the magnesium casings is flaking off in chunks round the carb /barrel, bearing in mind my pressure washer is nothing special im abit annoyed,anyone else had this problem ?

personally my dealer and i are against mag due to the heat makes them porous in time and they dont keep well

Pressure washers were invented by Beelzebub

I agree, keep the pressure washer for the patio (as long as you don't care about your patio too much).

This magnesium alloy motor must be getting on for 30 years old :-See Sadrob
