Banshee starts then stalls

[bansheeonfire]

Hi my son has a 2001 banshee with a twist throttle. I bought him a thumb throttle and replaced it with the twist throttle last week. The twist throttle cable was longer but i had a spare motion pro cable which i installed. Yes his banshee has the tors delete kit on it. I syncronised the carbs and now it fires up first kick and then just dies. Ran perfect before we put the thumb throttle on. Any ideas?

Did you mess with any of the air/fuel screws or maybe they got accidently bumped out of place?

Also compression is good and plugs are very wet. Checked spark. Lots. 

[bansheeonfire]

No. Touched non of that. And tube between carbs is intact. Also i did not put the left carb slide in the right side carb.

Also my friend who is a banshee expert who owns 12, yes 12 banshees says the plugs are fouled. I put in two new plugs wont start at all now.

where are the idle screws? crank em all the way in and see what happens

Does it have idle screws? Or where they adjusting it with the cable?

[bansheeonfire]

Yes it has the tors delete idle screws on each carb. I did not move them. I adjusted the carb sync by using the adjusting nuts on the carb caps. I cant see how turning the idle screws in will help. Its getting too much fuel as it is. I did not remove the carbs or touch anything else other than removing the carb caps to get the old cables out of the slides. I myself suspect an electrical issue. When i cut the wire ties off the main wiring harness maybe i disturbed a wire. We are going over it this upcoming monday and re-checking everything. It has to be something simple.

Check the switches.

Off on switches and key?  It has fullbore fenders on it. Ignition key is jerryrigged out the right side of the rad. Had to pull the old throttle cable past it to remove it. Good thought. I will check that the Ignition wires were not loosened when i pulled the old throttle cable through. Thanks.

you make it sound like its running rich as hell. Perhaps your pilot circuit is jetting too rich.  try turning your air screws out. If you kick it and it starts, if you stay on the throttle, does it stay alive?

[bansheeonfire]

Yes it is running rich. When it did start if you touched the throttle it bogged out.

Well my bad on this one. We checked all electrics and everything seemed fine. Lots of spark. We re-checked the carb sync and it was out by 1/16.   Readjusted the throttle cable and it fired right up and purred like a kitten. My son rode it for 20 mins said it ran great. The one throttle cable was not seated in the adjuster on the cap all the way in.  Lesson learned.

Well here we go again. The quad was running perfect and my son got it out for his first spring ride and the same thing. Starts then stalls. Was running great when we fixed it last time.
