If it still has the original paint or at least old paint close to original period would you be able to see any heat cracking or cooked paint in the front foot peg tube area from a front engine exhaust pipe used on the Hodaka? Or any in the rear tube area from the Tecumseh?Something you might be able to tell from possibly. Or extra rust in those exhaust areas maybe. A descent sn#or model# check of course would be best if thats available. Good luck with trying to figure it out.
