    I upgraded my Skyhawk 48cc with the 55cc hop up kit. It's now on a 1957 Schwinn Corvette Cantilever frame. I used RED thread lock on almost every nut and bolt--many nuts and bolts have been upgraded. I installed an upgraded throttle assembly.

    I totally feel a difference in power. At this time I am running it easy until the engine breaks in.

    I'll try to get some pictures up soon.

    Hahahahaa wanna race me?!

    What's in the hop up kit? How much does it cost?

    The kit includes an upper engine body, piston, rings, head gasket, and a bearing. Total cost is about $75. I recommend replacing all your head bolts and head nuts while you have the motor taken apart. Don't forget to red thread lock it all in.

    Yes, I would like to know sizes and specs.

    We will have the stud kits back on our new site soon, with better pictures and details.

    I don't know of an upgrade for the 66cc.

    yeah, if tehre was an upgrade to make the 66cc to about 75cc that would be sweet :D

    The engine is finally broken in. RUNS GREAT. I added some "Marvel Mystery Oil", and Some "Seafoam" to the gas mix, which I feel helps it break in faster and should make the engine last longer.

    Nice and quiet.
