I couldn't find this anywhere, so I'll post my first question. But first, a little info: I'm running a SkyHawk 66cc motor, everything stock, with an NGK B5HS plug. (The plug is a replacement, but was not beneficial to performance.) The motor has about 450 miles on it. Engine break-in was 2 gallons of gas at 20:1, run no longer than 10 minutes at a time, and no faster than 15 mph. It is still being run at 20:1 per dealer recommendation, and I have only taken it up to its top speed once. Generally, I baby it because I want the motor to last as long as it can.
When I first start the motor, it's VERY punchy and I have to be careful on the throttle. It almost seems as though the bike would rip itself out from under me if I turn the throttle too much. Once it warms up to operating temp, I find pretty much the opposite is true. It will still cruise comfortably at 19-20 mph, but getting there takes a good while. From a stop, it will 2-stroke up to about 12-13 mph, and then start to 4-stroke during acceleration regardless of throttle position. Half the time, I have to check my cyclecomputer just to verify that I am in fact accelerating. Once I've gone a block or so, the bogginess goes away. I hit another red light, and we start all over. And only when it's hot. Before it reaches operating temp, it will rip me out of my socks. Any ideas? Sorry to be long-winded, but I wanted to give as much info as I can to make responding as easy as possible. Thanks in advance.
