Split Hose By tycomike (Read 3,855 times)

The vac source for the PAIR comes for a 4-way coming off the manifold. The hose in the second pic goes into the bottom of the air cleaner. When I blocked the head on the reed check valve, that's when the engine started to sputter and hesitate. There is no pipe or hose that goes into the exhaust. Thanks Bashan.

Let's just make sure we're clear, a pipe would have gone into the head, the thing under the valve cover. As you look at the valve cover the PAIR should go into lower left to the cover. Now, is the spot that the hose went into on the air cleaner sealed off? You can't have leaks there either, it's like a vac leak. Rich

[tycomike]

That's correct Rich. It was sealed off. But the scoot was bogging and hesitating too much. So I put it back to the way it was. But then the hose melted. Thanks.

Can you take a picture of the front of the engine. I want to see the PAIR port. You can do a close up but also back up a little so I can see the valve cover and PAIR port. Also, I'd like to see where that hose went into the air cleaner and where the other end hooked on. Rich

[tycomike]

Ok Rich. I'll do my best to do so tonight or tomorrow. Thanks.

I don't want to be a PRICK but you are not following instructions and to prove it put up some pictures of the hoses on the PAIR SYSTEM FROM AND TO WHATEVER and then we can take your picture or pictures and label them to guide you what to do with each and every hose on there.

The reason it melted is because the valve is bad and not closing. It is supposed to only suck in COLD AIR. If the valve is left open then the hot exhaust gases is being allowed to get out and that is why it melted. So please take that crap off and plug it by the head and YOU NEED TO PLUG THE VACUUM HOSE GOING TO the canister AT ITS ORGIN. If that vacuum line is left open it will bog and not run right. ALSO if another hose from that system is going to the AIR INTAKE SIDE you need to pull that off the AIR INTAKE and PLUG the AIR INTAKE SIDE AS WELL OTHERWISE to much AIR will be sucked in and the motor will then run LEAN.

This is simple stuff to fix but you have to follow instructions otherwise we are beating a dead horse. Sorry to be so blunt but you have to follow instructions MANY and I mean MANY rich and I have told others how to take this off and actually other emissions are more complicated than this on their scooters.

If it bogs or whatever after you take it off all it takes is a minor adjustment to the carb BUT like I Said you are not plugging up things you should when you take the emissions off is why it is bogging.

So in reality you DO HAVE TO TAKE that crap off because the VALVE is not working as evidence by the melting hose.

Ok here's some more pictures. I hope this helps. Thanks.

First, this is a PAIR inlet pipe into the exhaust side of the head and exhaust system. This would be blocked at the head when removing the PAIR system.

Is that hose above the same hose as #1 in the below pic:

And the below pic does appear to be a vapor canister, not a PAIR canister. If it is, it is hooked up completely wrong in this pic. I meant vapor canister hose on the one label. I put "vapor canister?" on the canister because this is a mess. Did somebody redo this bike before you got it? Is it a used bike?:

And hose to bottom of carb? I have no idea where that could be hooked on. I need a pic of that. Just put it on photobucket and I'll retrieve it.

NEED to know FROM that valve ONE HOSE COMES FROM THE SIDE OF THE VALVE COVER, THE QUESTION IS where does the OTHER HOSE ON THE OTHER SIDE OF THE VALVE GOES TO? Because that Canister in the picture LOOKS LIKE THE GAS TANK VENT CANISTER.

I don't know where to start. I think there are two different systems somehow interconnected in ways they are not supposed to be. If the vac line is pulling on the tank vent it would sputter. Why is the vac line on the vapor canister running to the bottom of the carb and what could it be hooked to? It comes back to, plug the PAIR port on the head, plug the vac lines, plug the airbox openings, put a filter on the tank vent, and THROW EVERYTHING ELSE THE HELL OUT. Rich

Ok sorry the delay. I've been busy with my work. Here's what I've done. I took some more pictures. Labelled them (hopefully better).

This is the front of the engine.

So I removed Hose 1, and put a blocking plate in. Hose 3 just dangles out under the engine. Is that correct?

This is the air reed.

I tried a different style of hose. It too burst/melted on me, today on my way home.

This is the canister.

I have now removed the canister. It's sputters a little, and doesn't go as fast. I put an air filter on the line that went to the fuel tank. I also changed the vacuum tee from a 4t, to a 3t.

Any ideas are greatly welcomed. Thanks.

When you say you put a blocking plate on it DID YOU DO THAT BY THE VALVE COVER? If not that is your problem You take the two bolts off that the CHROME PIPE is connected to by the side of the VALVE COVER and you put a PLATE THERE. Then the entire valve and all that comes out.
If you blocked it at the VALVE no wonder your having melted hoses and not running right.

See where you have HOSE 1 take those two bolts out and put a plate over the hole and use the two bolts to hold the plate on DONE.
