    I picked it up for 200 bucks. Going to take some work to get to the point where I can test it.

    We shall see... worse case do a bonded title and add 100 to the price assuming the engine runs. Will be determining that first before doing the bonded title if I need to do one.

    That feeling you get when you are looking at a mess of wires and then out one pops from under some electrical tape and you start to pull the tape off and you see a butt connector.

    Also to add. I think the harness is mostly back on for my testing. Some hacked wires here and there. Mostly the fuse box and some of the indicator lights were snipped :(. I will probably clean it up more but I got the warning lights when I turned the key which was a welcome sign. It looked low on oil so I started filling it up so I could just see if she would crank over then I realized it wasn't low but overfilled. I pulled the oil drain bolt and gasoline and oil came flooding out. The previous owner did say that the carb was flooding the bike and that he bought a new float for it but maybe they never tried to start it after that. Or maybe there is a leak with the vacuum line or something. But a little bit closer to that first crank.

    Here is what I see inside... some bits and parts of what looks like the seal from the oil filter cover.

    Looks like some sort of sealant was used at some point. This is why we only use proper gaskets and o-rings.

    So I assume I should put a new o-ring here.

    Got a new o-ring for the filter housing. Started looking to put everything together and I went to get the gasket off of the bottom cover and found no gasket.

    Anyone have any real good tips to get this gunk off? I personally don't like using a razer blade. I always feel like I'm going to gouge the metal.

    Well. I decided to try the razor blade and to my happiness there was a gasket down there.

    Once I started to get under the gasket I pulled it off and then cleaned up the surface very lightly with the emery cloth there. Then I sprayed fogging oil on a paper towel and just wiped the surface to make sure to get any real fine particles off.

    Now I just need to make or buy a new gasket and get this back together.

    Should I try to get that black gunk off the inside there on that edge?

    I would just wipe up as much as you can.

    Well got it started. The battery I got with it is shot. Put my battery in it and jumped the solenoid and it turned over well. Got it started up with a heavy spray of starter fluid on each side then was greeted with hanging idle. Which is no surprise considering the state of the carb boots.

    20190623_155212.jpg 20190623_155207.jpg

    I sprayed carb cleaner and confirmed that the hanging idle went away.

    So now to source some carb boots. Considering the boots on Mike xs are maybe from China I was thinking about ok but trying to source them from China directly. :) But9 it we shall see

  15. Got mine off eBay I think. Seem to be working fine. Definitely import. Pretty cheap but took time to arrive

    Is the intake manifold gasket different than other gaskets for the bike? Just wondering if I can cut gaskets from my roll of gasket material or if I need to buy these gaskets. Anyone know?

    I couldn't fall asleep tonight so I decided to clean my friends carbs and turns out both diaphrams have very small tears. Anyone used the JBM replacement diaphrams with success? From my search it looks like at least a few people have used them with success. Anything I need to know as far as any rejetting or setup changes with the carbs in general if I go that route? Anyone tried to find a flexible glue that would repair small tears.

    So cleaned up the carb and I noted a few things that need replacing. Mostly rubber components.

    Pilot jet plugs are a little hard so I will probably replace those. Plus the pilot jet's themselves look different from each other. One has holes in the side and the other doesn't. Is this an issue?

    I had a couple of questions too about the o-ring on the mix screw but I searched the forum and found a thread where xschris helped another member regarding those. The mix screw o-ring was pretty flat. For the cost, I figure I might as well put new rubber on both mix screws also.

    One of the valve seat o-rings was hard and flat so it wasn't sealing well in the carb body. I could easily slide it in and out. I suspect this could be the source of the leak that the PO couldn't find since he probably did not rebuild them completely.
