Should I upjet my idle jet and or low speed jet on top of going to the #80 main jet?

[Alleyoop]

NO, just the MAIN JET

Ok so i have two more problems with removing the stock air filter that I need help with. Here is the picture of the first problem. If you look at the connecter that has that little blue zip tie around it you will see to the right of the blue zip tie the connector is connected to the big tube that goes from the air filter to the carb. To the left of the blue zip tie the connector is connected to a hose that goes from the connector to a little metal contraption that connects right into the exhaust pipe. The problem I have is when i install the new UNI air filter the tube that goes from the old stock air filter into the carb that the side of the connector that is to the right of the blue zip tie is connected to will be gone and the connector will just be dangling. Am i supposed to just leave it disconnected from anything on the right side of the blue zip tie and only just have that hose that goes to the exhaust connected to the left side of the zip tie on the connector, or should i connect it someplace else now? I started the engine with the side of the connector to the right of the zip tie disconnected from the big tube that goes into the carb and the engine ran fine but it sounded a little hollow, so i put my finger over the opening of the connector on the right side of the zip tie to make a seal and it sounded and ran fine. So i think i just need to seal that hose off but i am not sure and that why is why i am asking you guys. So what should i do? I have one more problem that i will take another picture of in a little bit.

So that HOSE is connected right on the EXHAUST PIPE if so you can block it of. Now check for any other hoses going from and to. It may have Vacuum hose on that metal box if so you will have to disconnect the VACUUM from it and block the VACUUM AT ITS ORGIN.
Also your pictures are awefully dark , put a light in there or wait until daylight to get some light in there.

One thing I noticed is your FUEL FILTER is backwards, the BIGGER ENDS on the FILTERS always go toward the CARB. You want the FILTER TO TRAP the stuff on the OUTSIDE of the FILTER. So when you see black stuff getting on the outside of the filter it is time to get a new Filter or take it off and see if you can blow the stuff on the outside out and have a clean filter again.

Alleyoop, the hose with the blue zip tie around it is the same one from the first picture. That silver metal box is what it is going into and that silver metal box is going straight into the exhaust right below it. Does that mean i can plug the end of the hose where it is in the first picture, or do i need to plug up the metal silver box? I am about to take another picture now of the second problem i am having.

[Alleyoop]

You can block it off at the metal box. You don't want a hose just hanging around. All that does is moves unburned gases back into the TUBE to get burned again by the motor. Now are there any other HOSES or pipes coming off that little metal box?

[curiousgeorge]

No not coming off of that little metal box except for the connection to the exhaust pipe. But there is a T adaptor with some hoses going to it that i need help with. I just got another flashlight to make it so i can take a clear picture for you. Also what can i use to block off the metal box. I just need a way to plug up the larger metal nipple that hose with the blue zip tie is connected too. Any type of special putty or something that will be good for that?

[Alleyoop]

Yep, the "T" are VACUUM hoses so you need to block take that off as well. What the Vacuum does is OPEN a valve inside the METAL BOX and allows the gases to go up through that hose and into the AIR FILTER TUBE.

What you can do is get JB WELD, autoparts stores have them get the 24 hour one and take the hose off the METAL BOX and fill the CONNECTOR with JB WELD and that will fix that. If your going to use the Air Box you can use that stuff on the plastic piece sticking out of the AIR TUBE that the zip tie is wrapped around. JB weld hardens like steel, you can paint it drill it etcc.

Now on the 'T" one hose goes to the metal box then one going to the 'T" should be going to the INTAKE MANIFOLD where the carb is ATTACHED TO (which is the point it creates Suction). NOW WHERE is the other hose on the 'T" going to?

So here is my second problem. So the big tube with the T adaptor coming out of it and the grey zip tie around it is going into my old air filter. The problem is there are tubes coming out of the T adapter that is going to be removed when i put in the new air filter. The tube with yellow zip tie around it is going to that small plastic canister with the pink zip tie around it. There are two things that come out of that small canister. One clear tube that has a little murky liquid in it that i assume is excess gas or just excess dirty water or moisture that got collected, and the other is a hose that goes into the top of the metal head where the valves are. So i don't know what i should do with the tube that has the yellow zip tie around it when i replace the air filter and that T adaptor is gone. The second tube that is coming out of the T adaptor is the one with the green zip tie around it and it goes into the charcoal canister right above. So i am not sure what to do with that tube once the T adaptor is gone either. So should i leave those dangling or plugged or just remove them or what?

[curiousgeorge]

When i mentioned the T in the other comment that had to do with the metal box i think i might have poorly explained, but it is not going into that metal box near the exhaust. It is coming out of a tub in the air filter as you can see in the picture above. Also so you know I will not be using the airbox because I am just going to directly hook the new UNI filter straight into the carb.

[Alleyoop]

Ok that is all EMISSIONS CRAP and you want all that stuff off. They cause more problems than carter got pills.

Now the HOSE from the VALVE COVER is that on near the TOP of the VALVE COVER? If so that is the VALVE COVER VENT HOSE you can put a FUEL FILTER on the end of it and just ZIP TIE it up high on the frame. It needs to VENT but sometimes the motor will spit out a little oil out through and get into the hose. So you want it up high so if any oil gets in there it will drip back into the valve cover.

The ONLY VACUUM hoses you should have is:
1. One hose going to your PETCOCK(Fuel Valve).
2. And if your Carb has an ACV valve one Vaccum hose going to there. But I do not believe yours has an ACV VALVE usually the 150ccs and up Carb do. The 50s usually do not.

So the only hoses should be is 1 from the VALVE COVER(VENT HOSE) and 1 Vacuum hose going to your FUEL VALVE and the GAS LINE and of course the one by the REAR WHEEL which is your TRANNY VENT HOSE.

Forgot to ask IS THERE another CANISTER and there would be a HOSE coming from the TOP OF THE GAS TANK? That also goes bye-bye and that hose if you have it also is a VENT hose for the GAS TANK and again put a FUEL FILTER on the end of it and zip tie it HIGH on the frame. You will have a much cleaner ENGINE BAY and very simple.

ok. i will take a picture of what i believe is the valve cover vent hose. and also what is the petcock and where is it located exactly? and yes i do have that gas tank hose going to another canister. I have three canisters all together. that gas tank vent one. the charcoal canister and lastly the one with that pink zip tie around it. are you sure i don't need to keep the canister with the pink zip tie around it because there is a clear tube with a removable plug at the end of it coming out of that canister and in that clear tube is a murky liquid.

[curiousgeorge]

Is the hose with the blue zip tie the valve head vent hose? Also do you know the hose with the yellow zip tie is? It came sealed off with a black zip tie when i first bought it.

[Alleyoop]

This is a 4 STROKE RIGHT not a two stroke?

The Petcock is where your FUEL LINE is connected to and it also should have a VACUUM LINE hooked up to it. The Petcock(or Fuel Valve) also has a valve inside and the VACUUM opens the Valve and allows FUEL TO FLOW to your Fuel Filter and to the CARB WHEN the motor is running. ONce the motor stops no more VACUUM and the Valve closes and STOPS the fuel from flowing to the CARB SO IT DOES NOT FLOOD.

Now your may have the PETCOCK(VALVE SCREWED ONTO THE BOTTOM of the TANK. Or it could be a STANDALONE PETCOCK which then there will be a HOSE from the tank to the PETCOCK.
