    keihin carb question

    Lots of info out there about pop off pressure. I can't get the needle to actually "pop" off. More like raises to let air by and the spring won't reset the needle without help. Might be a cheap rebuild kit, scored seat, bad needle? Tried a number of different springs even modified some but they either leak to low or way to high. Any advice?

    Make sure the needle is wet when you test,also with keihins if the pressure is built up too slowly the needle will open slightly.I have a pump tester but it's only good for the keihins,i tee a guage into a compressor line with a flush tap to pump air in quicker,the needle pops off everytime.
    Old skool rocks!

    Re: keihin carb question

    The whole problem with Keihin carbs, if you call it a problem, is that needles and seats are expensive. $35+ just for a CDKII needle and seat whereas the mikuni or WSM equivalent is 1/3 the price. And its something you change every few years and adds up. But, as water rat said, wet needle with wd40. I hook mine up to my compressor and vary the pressure with a dial until it pops off and seems to work well.
