I bought the speed kit new a few weeks ago but now the car insurane bill is comming and I really need the money. The kit was installed but the gaskets were never crushed and the engine was never fired. It was installed properly and still in mint condition, the only difference would be the packages are opened and the piston ring is on the cylinder. The kit includes a bitubo exhaust, 15mm Amal carb, 70cc cylinder/piston, all gaskets, engine head, choke lever and cable,intake manifold, and cable end. At 275 obo. this is definitly my loss but as I said I need the money.
