    Where to buy a stock size 125m piston?

    Does anyone know where I can get a stock sized piston for a 84-85 125m? I looked all over and could only find pistons for the 86-87 model. Any help would be appreciated.

    Well when I first got it I pulled it over and It seamed like it had some compression but very little. So i said what the heck and I squirted some starting fluid in it and it started. Later did i find out that there was a rag stuck under the intake valve from when someone must of blocked off the intake. The guy said it ran but smoked. I think it only had compression because the cylinder was rusty lol. Now it has zero compression. Do you know the stock cylinder measurements?
