motor only runs with wheels turning, but doesn't accelerate.

I figured I'd post this in it's own thread instead of being hidden in my Finally! thread.

The bike was running great today. Accelerated nicely, was pretty quick, etc.

So, all of a sudden it won't stay running. If I'm pedaling and the wheels are turning, the motor will run, but if I give it gas it won't go any faster, and if I disengage the clutch, the motor dies. Since the motor runs when the bike is moving, I'm sure I have fuel and spark. So what else could it be?

It won't accelerate and dies with clutch in...

I checked the plug and it was a bit oily/black, so I moved the e clip to the top notch and cleaned the plug. Of course this didn't really help.

Any suggestions?

Thanks

hi jason; bummer, it sound like no or very little gas is making it through your carb. i would start at the tank and work to the carb. the petcock might be plugged from stuff in the new tank. good luck. mitch

Hmm. I think tomorrow I'll try pulling the gas line off the carb and letting it run into the gas can and see how it flows. Once it's empty I'll remove the petcock and check it out. I'll see about removing the carb and checking it out tomorrow as well.

The tank isn't new. This kit has been around the block a few times. I just bought it off of some guy already assembled on the bike. Before I picked it up he had run some SeaFoam through it to clean things up, then filled up with a new mix of gas. This is actually the old-style kit that came with the separate orange-button kill switch (which is broken, lol)

well if it flows. pull the carb, a jet can be dirty. scootercatalog has a throttle and kill switch. a toggle works well

Does the throttle open the slide?

It feels like it does. I adjusted the throttle cable so there is very little slack in it, and I can hear a kind of click when I move the throttle.

I won't be able to get to the bike for another 8 hours, so keep the suggestions coming

It's just kind of disappointing, the bike was running like a raped ape for about 20 min, it was great fun.

I RECENTLY PUT A 80CC MOTOR (WHETHER IT IS OR NOT WHO KNOWS) ON A STING RAY DROVE IT AROUND THE BLOCK A COUPLE TIME EVERY OTHER TWENTY MINUTES UNTIL I THOUGHT IT WAS BROKE IN I TOOK IT ON ITS MAIDEN VOYAGE ACROST TOWN AND BACK TODAY AND NEAR THE END OF THE RIDE ITS WAS GIVING THE SAME SYMPTOMS AS YOU DESCRIBED AND AFTER SCRATCHING MY HEAD FOR A LONG TIME AND LOTS OF CUSSING FINALLY I NOTICED THE INTAKE GASKET BLOWN COMPLETLY OUT BETWEEN ENGINE AND INTAKE MIGHT WANT TO CHECK YOUR TWO ( SORRY I COULD HAVE SAID THAT SHORTER)

All gaskets are fine. That was one of the first things I checked.

Right now it's lookin like the magneto is dead. None of the resistance tests are working properly, and it's not putting out voltage on one of the wires when it spins. I have a replacement CDI and Magneto on order from thatsdax. Hopefully they get here soon. Anybody know what days Dax ships parts? Should only take a day to get here, seeing as he's about 45mi south of here....

I think he does parts daily
kits once a week
..I could be wrong tho
you could call to confirm I guess
