Hey Iam workin on a banshee in my shop and I cant figure out whats wrong with this thing , i cleaned both carbs , put new fuel and fuel lines on it and the fuel is on and so is the airbox and filter , no intake boots are even cracked , it was running ok when it came here but it would skip and stall out , now it wont even start for me , please help , thanks

 

also its all stock

 

Chek for spark and fuel, if both are present and still no ignition, chek compression.

 

Also replace the plugs.

 

all of it is good , iam stumped

 

If you have spark, fuel, and compression you should be all set. I don't have any clue on this one either. Sorry I couldn't be of any help.

 

thats cool man i even stump the yamaha techs lol hopfuly this thing gets running soon , thanks for the help

 

iam thinkin it might be the degree key , i wonder if its striped...ill look into that later

 

check the timing

 

Did you happen to put the slides in wrong? The carbs are setup where the slides can go in backwords if they are swaped between the carbs. The slides have a edge cut off of one side that should be facing away from the motor when installed right.
