I took a ride and fiddled around with that nut on the handlebars and every setting basically made no difference. Also may I add that when you're going fast with throttle and it starts to slow/bog down, if you keep holding the throttle down where it was when it's slowing down, it will backfire. Does this tell something?
I think backfiring means running lean... but the spark plug color was good when I checked it that time
Hmm it's almost like when you give it throttle, it goes well then gets sort of like starved for gas (the slowing down/backfiring), and the only way to get the performance back is to just let it idle without giving it gas... it's gotta be some fuel problem somewhere.
I'm thinking maybe it's running lean some of the time (under load) because of the backfiring. Maybe it could be something like it's draining the bowl under load and the petcock can't keep up. How would you check for blockages in the fuel line/petcock operation?
1.Remove gas line from carb
2.kick over motor with kill switch off
3. if gas comes spewing out petcock is good, slow trickle ore anything like that is bad.
I am not a mechanic, nor do I play one on TV. Actually my advice is probably worth slightly less than what you pay to view it.
u have an electrical problem. sounds funny? nope. my aero did the same thing, the headset wires were shorting out, making it backfire, run like crap, cut out, bog. check the wires.
Headset wires... where is that exactly? The thing DOES have some pretty sketchy looking wiring jobs though, but I had no idea it might be an electrical thing.
I did a check over most of the wiring again, and made sure any connections I could see were tight. The plastic connector box near the front with all the rows of wires was OK, but looking up through the bottom it looked a bit corroded in some places, and I tried to pull a couple of the molex connectors out but they absolutely would not budge. Anyway when I rode it everything was the same. But if it really was because of the wiring, wouldn't the scooter perform crappily from the getgo? I mean, when you first start riding it it's a beast and THEN gets worse.
the wiring? i find that hard to believe. the wires dont get warm and stop working. if it was a hair more random i might agree. but wires dont fail consistently. they just dont. i might not know a ton about those scooters but i rewired enough things to know that.

no, my aero would fire up fine, then accel nicely, then it would start stalling out at high rpms. i ended up haveing all the headset wire pinched, i fixed them, and it ran perfect.
