try ebay, what model is it?

my step dad has a few harley dual sports, they're the sx125 2 stroke he has the 1974, 1975, and 1976.

I bought one for my SX250, back in the day from Wiseco. Check their catalog. Troy341

Please post some pics of the bike!

I plan on taking some pics of my bike here in a lil while and I don't know if she's a 125 or 250. Cause those two motors that year look almost identical. And not only that don't know much about bikes but I do know a lot about cars semis and trucks.

it should say something like 124ccmcc or 248ccmcc or what ever the stock size is it could be by where the car connect to the cylinder or on the bottom near the base gasket, basically anywhere on the cylinder

Just sell it to me, problem solved.
