Hi, folks
Ive got a 1998 1500 classic with 2 inch v/h staggered pipes k&n air filter stage 1 dyno-jet kit that keeps fouling rear plugs
suspected ign wires at first so they were changed problem still came back sometimes 1 tank of gas sometimes 10 tanks of gas
suspected hydraulic lifters were failing due to old thin oil still no difference
have the hottest plugs in the bike now
leak-down tests great as well as compression
went over all electrical connections and still nothing
has a single carb feeding both cylinders so i cant blame jetting cause front cylinder plugs are burning perfectly
once i replace fouled plugs it runs like a dream again but unpredictable for how long
checked fuel tank vent was plugged once corrected it still fouled plugs and i mean fouled to the point where it would stop firing and cough and sputter
ive been scratching my head with this normally im pretty good at searching for these kinds of problems but this one has me baffled
