Finally used a sight tube today and set the floats. They were not off my much at all, like 2 mm. I guess that means the float vavle assembly is working correctly. I have to go to a family function, so Ill give another update tomorrow.

OK guys, like I said, I hooked up the sight tube and finally got my float levels set properly. I went to fire the bike up after sitting for over 5 weeks and it started on the second kick. It didnt take but 10 seconds for my left cylinder to start gurgling and farting. I put my hand over the left pipe and it felt like it was barely pushing anything. Remember, this is and always has been my problem cylinder. I am seriously done with this machine. I have done every single thing more than twice and nothing helps. Im pretty damn certain my problem is in the fuel mix, because all of my eletrical is spot on. My left plug was black and sooty after only 20 seconds of idling. Mixture screw was half way out as well. Someone please say somethign to make me feel better.

Josh, with a clean plug in place, does the left cylinder respond to the left mixture screw at all if you turn it in with the engine running?

Dick, it does not respond. That was one of the things I tried right away.

OK, Josh, you've eliminated the float mechanism as a problem, since the sight tube will run high if the float valves aren't sealing no matter what level the floats are set to. The problem preexisted the ignition change and you're getting spark, so I think it's safe to rule out ignition. There was no defect in the pilot nozzle, fuel screw or fuel screw seat that I could see in the carb set I gave you, and the intake air jets were clear; but nonresponse to the fuel screw points to a problem in the pilot circuit or the choke seal. Take a close look at the float bowl gasket; is there any blockage at the outlet of the pilot air intake? What happens when you remove the right side air filter? If all else fails cut a piece out of a plastic bag the diameter of your old choke plunger, stick it on with weather strip cement, and see if that clears things up. Gasoline will eat the plastic up and make a mess after awhile so don't run the bike on the street that way, just stick it in there long enough to test. Apart from that I'm stumped!

Just for something different, try putting the spark plug leads on the opposite plugs, then if the problem is on the right hand side it must be a bodgey coil.

I have an electronic ignition with a dual output coil. Does this matter?

Well, it shouldn't make any difference with a dual output coil, but, from what you have gone through, it's worth a try.

Ive had this problem long before my new ignition and coil. I will give it a shot though. Seems like Ive tried this before, but with my previous points ignition set-up.

Guys, It was my compression all along. Im only pushing 90psi in my left cylinder. Time for a leakdown test. I assume its in the valves somewhere and not through the rings. Looks like round 3 of tearing this thing apart.
