  2. 28mm Keihin issues with clogging

    in Jetting & Exhaust Forum

    Posted

    Hey guys,

    In have a built trail bike.

    Talking about the carbs so only thing that matters, has a woods port, uni filter, dmc exhaust, vf4 reeds, and 28mm keihin carbs.

    Bike runs great when it runs. The carbs get clogged constantly, every hour or so. Have to take them off and clean them out. I have had many banshee and never had this issue with mikuni carbs.

    Is this a Keihin thing or my bike?

    It has an inline filter and stock fuel lines / petcock

     

    Thanks in advance

    I threw the stock carbs back on and it runs great. I got the needles to hold on the 28 pwks, I also put the leanest jets I had in it, 135 mains and 40 pilots, no real change. There has to be something that fell out or is off with the pwks. They are my first set of Keihin carbs. Is there anything stupid, kind of like the choke tube on stock carbs that could be doing this. The only thing I saw on the parts diagram, https://images.app.goo.gl/gehY7xU8U5T7cBsH8 for the carbs that I am not sure about is number 34. When I take out 35 needle jet holder there is nothing that comes out with it. Is there supposed to be something there?

    Just the stock cap for th fuel tank. Float needles will not hold any pressure. Bowl off carb upside down I put the guage from my leak down tester on the inlet. Will very verify hold until 3 lbs or so and then fall off quickly. Sprayed some wd40 and it is leaking from the needle. These carbs are brand new, 3 hours on them. Is the needle supposed to have something it seats into, or just the housing of the carb? Anything I can do to fix it besides getting new needles even though the are practically new

    Yeah slides are the same height, carbs synced. Compression is good. 125ish on both sides.
    It runs well the 1st few seconds after I start it then it starts smoking a lot and is real boggy, won't idle, but won't die if you keep on the throttle will rev about 60-70% of the way out. If I shut off the fuel it runs well for a few seconds before it runs dry. Leads me to believe it is rich but I went from it running well with a 154 main and 50 pilot and now I have a 148 and 48 in it. Elevation and temperature no real difference between running well and this now
