Help me with my 2012 motorbravo Super Hornet * By kttb (Read 1,079 times)

Hi i just bought a superhornet and the problem is it barely reach 15miles per hr , the owner told me it has a vaccum leak so i need to change the vacuum hose,
Another thing is sometimes i need to like shake (idk the word but i have to move it around) the red cable with a white tube for the bike to start or else it wont start and i heard a click, can someone tell me how to fix these things?

Red cable white tube

[Bashan]

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.

Thank you so much for the reply and the helps , i think imma need a lot of it, and what if the wire is loose , what do i do, change them?

[Bashan]

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.

Thank you, what do you think is the problem fof the bike running slow? I feel like theres not enough air, should i change the carb?



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?

[Bashan]

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.

alright , thank you so much , sorry ,
but im trying to replace the vacuum lines right now and i just noticed my bike doesn't have the T section , mine is like this, 1 of the intake manifold vacuum port is connect with the carb air cut valve , and the other port goes straight to the vacuum fuel valve , is this right or do i have to change it to T Section? 





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?

[Bashan]

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.

So should i adjust the idle screw then?

[Bashan]

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.

So sorry. 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?

[Bashan]

Oh foolish Earthling! Valve adjustment by moi! Look in the Library, there's other tutorials and videos on the subject. Don't take it to a shop, it's not that difficult. Rich
