My son just purchased a 1994 TTR250 Raid 1994 model. The bike is in pretty good nick, but the fuel tank is rusted out due to long term storage & water impregnated fuel. We live in outback Australia, so all purchases are internet based. I need to know if there are any plastic tanks available for this model, or can be adapted to this model. I don't really want a bigger tank, just something to replace the stuffed one. Any assistance would be appreciated
