    That is really cool. The new CDI says it has a higher redline and more timing advance. I think God of Speed got the same one a while back.

    I think that the connector was changed in '85. I didn't have to change any connector, it was plug and play:D.

    I have it as a spare now, managed to get a NOS XL600 CDI from Honda..

    I got the new PG in the mail and resistance is 411. Manual says minimum should be 511-585. I guess it doesnt matter as long as it isnt way off the mark. The old one is 112.

    my official honda genuine XL600 shop manual gives a value of 450-550 ohms for the pulse generator. Still a little low at 411, but closer to the value if that makes you feel any better.

    If you didn't zero your leads you might even gain another ohm.

    I got it running. The PG was fried. This bike runs like a raped ape. Smooth and boatloads of torque.
    Here is the list of work done as a recap.
    Engine dynamics head with black diamond valves.
    New cam a la mcma111
    2 rockers
    Wiseco .040 over 11:1 piston
    New PG and CDI
    New swingarm bearings, lower slider rear turn signals.
    I got a bunch more work I am going to do but this was a milestone.

    Glad you got it going. New bore with compression and sealed valves make a world of difference alright. Puts a smile on your face when you twist the throttle.

    I don't know what it is about theses bikes, but when they run good they are so endearing they make you want to fix them up and keep riding them forever.

    Scored a clarke tank for 75 bones plus shipping. Gonna install my clutch Sunday. Hope the tank makes it before my weekend ride in a couple of weeks.

    Where are you guys buying the clear carb vent tubing? The XL600 uses two sizes and the black vacuum tubing from autozone swells when exposed to fuel.

    Go to an outdoor power equipment shop. I used to work at one and they have a huge selection of small gauge thin walled tubing like that.

    So, I've been fighting with the carburetors on my '85 for quite some time now. A while back, I posted about an air cut diaphragm... That fixed one of my problems.
    I've gone over both carburetors with a fine-toothed comb several times, made sure that all the passages were free and clear, changed all the gaskets and other rubber components... Still, I have an intermittent problem of it leaning out. I'm almost to the point of finding a different primary carburetor. (If anyone might have one collecting dust?)

    All of the jetting is stock, and shouldn't be the source of an intermittent problem. The thing that I keep coming back to is a float sticking closed.

    Did you clean out the emulsion tubes under the main jets. They collect grit and don't atomize properly.

    The emulsion tubes are clean, all holes on all four sides are clear.
    Also, the float levels are correct when the bike is up on a stand (flat and level).

    For being an intermittent problem, this really vexes me.

    Have you adjusted the timing of the secondary carb? I had a bit of a bog a long time ago and adjusted the secondary tang to let the secondary come in a bit later. Worked good.
