    1993 Intruder 1400 Backfiring

    My Intruder has not been operated since 2008. The floats were stuck and I cleaned all that out. There are large pistons on the intake side that operate by action of a diaphragm. They are sluggish and I was wondering if this could be the cause of difficult starting, poor idle and a lot of backfiring. Waiting for new air filters and was hoping this maybe all it is now. Thank you for any help.

    LIkely that your low speed jets are plugged up.
    They are small and hard to clean.

    Get some Berrymans B12 Chemtool (yes, that brand exactly).
    But 2 OZ per gallon in the tank with some fresh gas.
    Run til hot then let it sit overnight.
    After doing that a couple of times you might notice a big improvement.
    If not, you need a mechanic to rebuild the carbs.......or replace them.
    Don't believe everything that you think.
