Help..the Banshee Wont Start!


Recommended Posts

the banshee is not getting fuel...i have cleaned the carbs really good, the reeds are fine, i pulled the head and the pistons needed rings and the cylinders honed....well to make a long story short we put it all back together. shee has more compresson now than she had before.... BUT the damn thing is still is not getting fuel. Fuel is getting to the float bowls, as it was before, but thats as far as it gets...could something be together wrong....i wanna ride sometime this winter....

1. Clean petcock as stated above

2. Check fuel lines for obstructions

3. Make sure the petcock lever is turned to the open position, that one has go many people in the past.

Tap the sides of the carbs, sometimes when they sit for a while w/ no fuel the seals dry out and won't open or close....

you were having this same problem before the topend rebuild, correct?

how long had it been since you had ridden it before this happened?

how sure are you that you cleaned the carbs good? did you use

compressed air to blow out all passages?

you can have someone spray a volatile areosal (most carb cleaners work

pretty good) into the airbox (remove the filter first and clean airbox real good)

while you kick it over. if shee pops you can be sure that it is just a carburator

problem most likely and then go from there.

you may already be aware of this but if not -- when you had the carbs apart, did you make sure not to get the bowls switched? the left carb contains the starter jet, and they have to be on the correct carb or shee won't start without kicking till your foot is blue, or towing it and catching it in gear. i found that out the hard way too. also make sure the equalizer tube between the carbs is in place, or you'll have the same results.

i was just went out for a ride one day, got back, shut her off, and she wouldnt start back up....its been like this since thanksgiving....i always do one carb at a time so i know that the bowls arent switched.....i guess im goin to pull them off again double check my work....anything else i should check for when i pull them?? my friend told me something about air leaks..... could this be true also????

This has happened to me a couple times after pulling the carbs, and i still haven't figured out why it happens.???

 

to get past it i would just pour a very small amount of fuel directly in the cylinders (through the spark plug holes). This would fire the motor and siphon the fuel where it needs to be and everything works after that.

 

Give it a try. if it starts, and then dies....that means you burned the fuel you put in the cylinder, and there is a block in the fuel system somewhere.

i don't know how much the tors would affect this, but i've heard it can do some crazy shit when they go bad. try unhooking it and see what happens. do a tors search to find out more details about it. i think all you need to do is follow the wire to a little black box on the frame and unhook it there.

The left carb, (the one with the choke knob) will have a float bowl with 2 brass tubes in it. One is the overflow tube, and the other is for the fuel enrichment circuit, (choke). If this bowl is not on this carb, than it will not draw fuel when the knob is pulled. Now, when you put the carbs back in, did you put the crossover tube back in? Not the balance tube, but the small black "hose" that connects between the carbs. It's about 1/4" I.D. and 3" long. This must be in place or the right side will run lean.; You said you went riding. This tells me you got it fired up. Does it idle? Does it run like you want it to. It sounds to me like the jets are clogged and/or the float bowls maybe switched. Also may want to check that the slides are in the proper carb. They can be switched. The cutout at the bottom of the slide needs to face the air cleaner. How do you clean the carbs. You said you "chacked everything out real good". What does real good mean to you? Just pulling the carb off, and shaking it around a little, blowing on it doesn't do a whole lot. You need to completely disassemble the carb, and clean it thoroughly. What is the compression on this motor? You stated it was "more than before". What is the reading? How did you check it? Old fuel? new fuel?
