Go to Ebay, check for Chrome Pro motorcycle batteries. They are great batteries; they even have a built in voltage and usage meter. I paid about $35.00; ships free; 8ah. Better yet; I went straight to Chrome Pro battery online and think I got it for a couple bucks less.

Damin:
My first post; I haven’t even got a scooter ( on order).
If you haven’t got the problem fixed, go back to you first post, “So top end rebuilt.” Your problem is text book; when a top end is rebuilt I’ll bet my left one that you don’t have enough valve clearance.
I know I might be preaching to the choir for a lot of you but when you have a fresh top end, new engine or new scooter, the new valves, against the seat, will start off with a high point. It’s not that the valve doesn’t seal; but it sets in a bit after some run-in making the .006” clearance maybe .005”. This effect is less with more precision made engines (Japan) and maybe more so with not so precise (China). This is why China scoots need a valve adjust after a few thousand miles.
Second, the engine may start well cold but when the engine heats up the valves expand which means the valve stem lengthens so now your .006” clearance is maybe .002” (which is why you have some gap in the first place), but if you started with only a .003” clearance you end up with ZERO and then it starts holding the valve slightly off its seat. It starts and runs well cold but then starts chugging when hot. If I’m wrong than I’ll have to start betting with my right one.
Ride On! Ironwire.
