You mean this cable and tube?
That's your main fuse and power cable to the ignition switch. If you have to jiggle it there's a loose connection somewhere. You'll have to trace the wire and inspect the connections. Also check the fuse inside the plastic tube and check the connectors.
Here's your vac and fuel lines:
I'm not sure that's your problem but it wouldn't hurt to replace them and see what happens. You can use 3/16" fuel line for both. Change your fuel filter also.

You might find that the screw holding the wire is loose and then yes, just tighten it. If it has a bare spot on it you'll have to replace the wire. Open the fuse holder, the white tube, and check the connectors on the fuse, if they're loose you may need to replace the holder which they sell at any auto parts store. Also I'd just replace the fuse, they're not expensive.

And what is this cable 
my friend say the airflow of the bike is bad i need to change the exhaust and the air filter, is it right? |

No, don't change the exhaust. They are capable of running a decent speed while stock. The carb is fine also. Check the air filter and did you replace the vac lines yet? Also, did you set the valves? That can really affect performance. And we talked about the fuel filter, have you changed it yet? You have to get these things off of the table so we can sort things out. There's too many variables going on here, we have to remove some.

Yellow is the T section Blue is my vacuum lines |

By the way, this is your crankcase breather reservoir drain. Take that plug out of the end and drain the oil once in a while. That should work fine on your vac system. You just have to have every nipple to the vac system attached or plugged. It doesn't matter on the configuration of the line and connectors. While the engine is running spray a little starter fluid around the intake manifold, if your RPMs speed up you have a vac leak at that spot. |

Tks for the reply, i just replaced the vacuum lines, and instantly the bike sounds loader. I havent test the speed yet but i hope it got better, im about to change the fuel filter. 1 question ,my rpm speed when the bike starts up is about 1800, when i accerlerate the speed goes up to about 4000 , is it bad, do i need to adjust the idle screw? Oh yeah while i was fixing , this thing came out of the bike, do you have any clue of what is it?  |

You mean while you're riding the RPMs go up to 4,000? They can go up to 8,000 and above. If they only go up to 4,000 that's a problem.
I'm not sure what that part is, all scooters are different in subtle ways. I'd guess it's something to do with the air cleaner system.

No, the idle screw only controls the engine when the throttle is completely closed. It simply holds the butterfly open a little more to keep the idle up so the bike doesn't stall, or slows the idle down so the bike doesn't try to creep fprward because the idle is too fast. Maybe I'm not understanding what you're saying. Can you explain the problem a little more? I don't think we're on the same page here. The idle screw has a limited effect on the engine.

Its my bad , i though the idle adjustment has to do something with tbe rpm and the engine. Hey , is there any guide about the valve adjustment , or i should bring it to the shop to do it? |
