Ground wire is attached to the 'head stud"? Is that the valve cover bolt, or the cylinder head bolt? Either way, not a very good ground point. The jug is separated from the crankcase by a paper gasket (no conduction there), and the valve cover is separated by a rubber o right (sort of), so no conduction there. Can't believe there is an electrical lug under a cylinder head nut ... maybe something on the side of the head? Ground path can only be thru the head bolts or down the valve chain. Anyway - there isn't a ground directly on the crankcase anywhere? The ground strap is connected to the valve cover on more than half of all models. Yes Jerry you are correct I have been seeing them on the valve cover more and more. My first two scooters were on the fan cover bolt at 12 o'clock. I like the starter hold down bolt. John |

Ok, I switched to the other performance cdi that I know works, but it still wouldn't light. But get this... the last time I was able to get it to run, I shredded a drive belt. And basically it hasn't ran since I replaced the belt. Well just now I removed the belt in desperation...and it fired right up! So now I'm at a loss as to why it won't start with the belt on You have a cvt issue . the CVT is being held back from a possibly bad bearing issue. Have you checked the gear oil recently ? This is the second belt to break in not many miles at all. If your belt is snapping , you have a CVT issue. What's happening ,is with the stock bore , its much easier to turn over , even with the CVT issue. With the bbk , and the CVT issue it is much harder to turn over. This explains the black plug. The plug is igniting, but the combustion is not powerful enough to kick the engine over. did you remove the variator and clutch assembly after the belt broke? John |

in general the bolts that mount the starter are on the left side cover for both the 50 and 150cc engine, the starter grounds where it mounts. the heavy engine ground is for the high current from the electric stater not the ignition system.

I have seen the engine ground under a valve cover bolt, I don't care for that spot. I prefer on the fan cover bolt or on the front of the cvt bolt cover towards the front.
the grounds come from the battery negative terminal with a heavy wire then bolts to the frame with a few wires at that point all of the connections from the battery on need to be checked cleaned the crimps and all. I bet it smoked when you were using the electric starter.

Where does the white wire go, you need to trace it , I know I can make the regulator I have work but I must know what the white wire is doing and going.

I would order a new head, and if you can repair the old one keep it as a spare.
