Troyota is most correct. Take it from us old guys. Rice burner is any Japanese vehicle. This includes motorcycles and MAYBE originated with 60's/70's Harley guys referring to Honda's and such. They used to say "I'd rather push my Harley than ride a rice burner".
Funny thing is I would ride my Honda past many a broke down Harley back then. Just like my '88 Supra of which I'm the original owner has been in the shop once (blown head gasket) in the 23 years I've owned it. Any american car I've owned is usually in the shop 23 times in the first year of ownership. No wonder Toyota is taking over the car market and GM is going down.

Remember...rice burner is ANY Japanese vehicle and this term should be considered a compliment to anybody with a brain.

If you want to create some less flatering slang for poorly modified rice burners you should target the guilty owners who ruin their cars. "Fried rice-head", "Sticky rice-brain", ...whatever...it's not the car's fault.
