    4 filters = pods = reason for large fuel jet. This was an attempt to make up for the lean condition the pods create.

    If you don't know what pilot jets are, then you haven't cleaned the carbs yet, and didn't read Rick's "Whole 9 Yards" carb cleaning post (search for it).

    Without checking valves (I think this is more "fun" on an X) or compression, you could be trying to revive a dead engine (or not...but this is a quick way to figure out where you are actually starting from).

    Clogged pilot jets would make it really hard to start (b/c it's using the pilot circuit of the carbs).

    Consider getting a proper air box...if you don't want to troubleshoot and tune forever (and since you already got the proper jets)

    any progress on this? If you are going to go with a stock airbox I might be willing to take those pod filters off of your hands for you as well as the larger jets you have. I could even pull my stock airbox and new air filter and we could work out some sort of a trade.

    I'd jump at the opportunity to get back to a Stock Airbox and Carb Jetting.

    Sooo much easier to get within the "Window of Fine Tuning" with the Intake Air and Carb Jets Stock.

    Whatever happens here ... DON'T Wreck The Airbox.

    OK.
    I know it's a tough decision.
    Paper. Plastic.
    Classic Rock. The Classics.
    Win. Place Show.
    Less Filling. Tastes Great.

    Air Cleaner Pods are a totally cosmetic Modification which inevitably causes difficulties inn Fine Tuning which have not been solved, to date, for over 30 years by Legions of frustrated owners having Constant Velocity Carbs. You will enter the arena where endless experimentation will resolve nothing and the bike will remain unable to be Fine Tuned for a variety of issues.

    Stock Airbox and Rubber Joints.
    Various degrees of Fine Tuning can be achieved and maintained without too much difficulty within a few hours of Fine Tuning.

    I'm sold.....the stock airbox will be staying put as long as it doesn't get in the way when I go to hardtail it. That's not going to be until next year at the earliest though, so I'm good. Thanks

    Yes, a little
    It starts really well now, just needs a tiny twist on the throttle (no choke). It idles really high for a while, then drops and stalls. It doesn't like to idle unless it's too high.
    Riding - it doesn't like to rev from about 3000-9000 rpm (it's slow and i can hear popping noises). Beyond that it's fine - before everyone panics, I only tried once for the sake of testing.
    I looked at the mixture screws they were all 2.5 turns undone.
    I did that revving to 5k for a bit and turning it off. The plugs were black.

    You need to synchronize. See my gallery for a synchronizer.

    You should adjust your valve clearances before you synchronize.

    My bike would not start well nor take throttle well.

    RickCo's carb cleaning instructions followed by valve clearance adjustment and finally synchronization made my bike a joy to start and ride.

    You have to do all 3, carb clean, valve clearance adjust and then synchronize.

    Anything else is half a loaf.
