    That will work fine. In the end all you would have to do is run a wire from the taillight to the acc to use the key switch as a headlight switch

    Okay so checked fuel delivery. Pet cock and float bowl drain. Fuel runs thru petcock fine. The fuel looks clean. Now the float bowls -coming out of the float bowl on the number 1 with gas off is the green fluid.. smells weird Like fruity almost but not definitely fruit but color def green lol.. looks like freaking antifreeze almost. Nothing comes out with fuel on. Then out of number 2, with fuel off it started leakimg out and was yellow color, smelled fine to me. But towards the end of the drip, was turning a green color. I'm not great w pinpointing smelling btw. But the first one was definitely a spoiled sweet smell almost. To make it easier for me I circled and numbered the carbs lol. And there's a pic of the green liquid and the yellow. I'm gonna say that I need to clean my carbs?

    Almost looks like someone dumped a box of jello in the gas tank. I now really curious what the inside of the tank and carbs look like.

    Am I wrong or should the inside of this carb be gross as hell? Lol it looks freaking clean as a whistle. Except the outside, but the entire bike looks like the dude dumped oil on it on the outside lol

    I'm not really sure how to take a pic of the inside of the tank that would be able to be seen lol

    The right picture is that the valve and brown rust inside the cylinder ?
    I empty my tank every winter and would do it in your case flushing it out
    The carburetor looks dirty and I would try cleaning it as much as possible without trying to loosen the angle bar at bottom

    So the pics def don't do justice lol but no it's not brown rust it's hard to explain it looks like the black carbon paint they put on truck beds and stuff idk what exactly it's called haha but that's what it looks like. I was gonna maybe shove a qtip down there and see if it comes off a bit or if it's like a paint or something... And the carb is absolutely disgusting on the outside but the inside is super clean it doesn't even look used almost, it has a tiny to it because of the lighting and flash but it's actually really clean.. I'm honestly going to take it apart and clean the entire thing and if it needs new gaskets and seals I'm gonna get a kit.. but hoping the whole thing is that clean and maybe it's the float that's messing up or something I'm not sure.

    Alright guys. So the one at the top of the second pic is cruddy and the floater doesn't go up and down freely like the one on the bottom.. the bottom one is pretty damn clean though. Gonna clean them both anyway, the outside looks terrible anyway lol

    The carbs look a lot nicer than the insides of mine did. From the description of the smell and the look of it the green stuff could be antifreeze. I don't think you will need any sort of kit which I don't recommend anyway. Read and follow the carb guide and put them back together. Pay special attention to the choke and idle circuits because the jets and passages are smaller so easier to plug up.

    Onward and upward

    So I broke it down and it's pretty gross inside the one. I'm trying to find a rebuild kit that isn't 50$ each like TC bros.. but the ones I keep finding don't have this piece. What in the name of god is this called? Not a shaft lol but that's all I can think to call it. It has mini holes. And I'm watching a rebuild video and all of them say to replace it if it's junk looking which mine definitely are crud filled lol. The gasket is really bad too so I'm gonna get new ones and over all just gonna get the gasket kit, and then two new of those shaft things if I can find one. If I have to I'll buy it from tcbros but eBay has awesome cheap gasket kits and have alot of parts w it just not this thing. It's the shaft underneath that nut I'm pointing at w the screwdriver

    On a side note about the antifreeze, does this bike even take antifreeze, and I'm definitely going to say it's NOT supposed to be in the carbs lol

    Yup, that's the needle jet.

    You might be able to clean things up with ultrasonic? Be careful cleaning brass parts such as the needle jet, and especially the needle which slides up and down inside that jet. Any vigorous cleaning will remove metal, which will affect the fuel metering function of the carbs. So better to rely on solvents, ultrasonic or wiping with a cloth. Best to avoid emery or metal brushing of the brass parts.

    Or buy a kit, but make sure you get the right parts in the kit. Different sizes of main jet, pilot jet, needle size and needle position are the main ways of tuning the mixture on these engines.

    Might be that somebody has put antifreeze in the bike, maybe to protect the tank from rust? But modern fuels go gummy and green when left for a long time.

    Looks like progress!

    Thank you! I caved and bought a kit from tc bros.i had to order a makeshift kit from eBay though because apparently tv bros only had one. Out of curiosity, is every single part for an 81 discontinued? It's so hard to find anything for it! But does fuel also smell sweetish after so long? Ive never experienced oldfuel lol .

    Looks like your pulling the motor and doing a valve job at least. That stuff could have got all over the pistons and into the ring groove and valve seals

    So these screens on the bottom of my float valves are non existent. Can I live without them? Can't find them online to buy lol. Read mixed opinions on if I need them or not. But they're just not there lol

    Cant remember Mr Skull has been wrong and it would not be entirely surprising
    if there is a need for a engine job .But that is a Big job
    I would now pour in a little oil in the cylinders.
    That green stuff does it burn if you try to set it on fire
    ( a small piece in a can or so )
    If it is antifreeze perhaps it is something that the combustion can get rid of if lucky.
    Have you stepped on the kick for compression evaluation
    If not don't do it before oil is in.
