Attached is a speed kit (Athena?) that I pulled off a Tomos Targa that I purchased yesterday. The cylinder still has it's cross hatch marks and the piston and ring looks like new. I don't think that there is more than 200 miles on this kit.. It also includes the Amal carb, carb cables and choke lever. The only thing that is missing is the air filter for the carb, which I'm told, is easy to replace.
I don't know squat about performance parts so I can't tell you if it's a 60cc or 70cc kit. I can tell you that it is like new.
I'll sell the whole kit for $150 OBO, or I'll trade it for a stock NEW Tomos A35 cylinder, A35 piston and rings and the stock Dellorto 14/12P carb.
Email me if interested.
