x_doug_x Posted June 28, 2009 Report Share Posted June 28, 2009 ok, so i rebuilt the top end in this banshee. started it and it was missing on one cylinder. so i pulled it apart and the cylinder that was missing had a clogged pilot jet, i cleaned it out and put it back together, it started firing on that cylinder and stopped firring on the other cylinder, i tried changing the plugs. didn't help, i switched the plug wires and the same cylinder was missing and same one was firing as originally. so i pulled the reeds out and happend to have a set of stock reeds that closed completely as the aftermarket ones didn't i put these on and it seems to be hitting on both cylinders now, still misses a little though "i think" i also pulled the plastic cover off the stator. i pulled the magneto off and cleaned the tip with a wire brush, also cleaned the 2 humps in the flywheel or whatever you call it. i can't find my gear pulled so i couldn't pull it off to try cleaning up the inside of flywheel and outside of stator. now it seems to be hitting on both cylinders but won't idle it only hits when i rev it up like the low speed jets are clogged again. this is driving me nuts. before i changed the reeds out i put a spark checker on it and with the gas about a quarter throttle it would act like it wanted to die then hit again and run for a second then act like it wanted to die. the spark checker said the cylinder that wasn't wanting to fire was firing when it was hitting but when it tried to idle down and die a little the spark got slower.... on the good cylinder it said it was firing all the time. but like i said, changed the plug wires and still the same problem on same cylinder...... PLEASE HELP. Quote Link to comment Share on other sites More sharing options...
x_doug_x Posted June 28, 2009 Author Report Share Posted June 28, 2009 i would also like to know exactly what the screws on the throttle housings are for "housings with plug that goes onto top of carb" i'm assuming the small screw on the back of each carb is a air screw?

AKheathen Posted June 28, 2009 Report Share Posted June 28, 2009 did you replace the just the wires, or the caps, as well. the big screws on top are the idle screws. sync the carbs, and check the pickup gap Quote Link to comment Share on other sites More sharing options...
x_doug_x Posted June 28, 2009 Author Report Share Posted June 28, 2009 (edited) did you replace the just the wires, or the caps, as well. the big screws on top are the idle screws. sync the carbs, and check the pickup gap gaps in the slides are the same on each side or really close either way. seems to pick up on both cylinders at 3/4 throttle and above. i have removed low speed jets and cleaned them about 6 times, this time one was clogged again and one wasn't and now i have installed a inline filter. i ordered new jets that should be in, in about a week. hopfully that will solve it and about the "plugs and wires" i took the complete wire/cap off one cylinder and put it on the other and vise versa and the same cylinder missed. i guess these motors will fire with the plug wires on either side.

fastbanshee8 Posted June 28, 2009 Report Share Posted June 28, 2009 If crud keeps plugging both pilot jets, it's time to drain, and flush out your gas tank. There should be two screens in the tank, that need to be cleaned also. If you have that much dirt in your tank, that it keeps plugging your pilot jets, it's only going to be a short time, before that dirt clogs up the inline filter, causing a lean condition, and very possibly blowing up the new top end. Spend the extra time to fix it right, so you don't have bigger problems, costing you more money, later on. Quote Link to comment Share on other sites More sharing options...
