    Strange Carburetor Behavior

    While I had the engine out of my chopper project I decided it would be the perfect time to riase the needles a notch. When I was riding the bike it ran pretty good but the pipes were showing hotter than I thought they should. It has pods and 4 drag pipes, dynojet stage 3 installed. When I put it all back together I put a few ounces of Lucas fuel conditioner in the quart of gas used to fire it up. It ran like crap! I let it warm up good and very little improvement. I pulled the plugs and they were wet. I lowered the needles back down and started on clean gas. A few minutes later it cleaned up and had that crisp response I had before. My question-do you think one notch would make this big of a difference? Was it the overly rich fuel conditioner? Both? No ride yet, waiting on the tank and fender.

    I can move the needles in my 850 with 4 into 1, K&N and stage 3 and have about the same results your talking about.
    Very big difference with just one notch.

      You made two changes. But one notch will fix/create a bog.
