Not sure of year. I got this for next to nothing with a blown motor. I had the cylinder bored to match a new piston which I installed along with new gaskets. Starts and runs but carb is giving me trouble (jetting issue I think---there is a dead zone between the low and high rpm fueling and it won't rev to full rpm in the higher gears). One tire has a slow leak. Come get it if you want to mess with it. Call Chip (me) at 484-880-0684 Thanks.
