my 03 banshee is running like crap

[bhautala]

hi i have a 2003 banshee, i have bored the cylinders out 60 over, fmf fatties, and a boost bottle, i just put a K&N filter on it. and the TORS eliminating kit. i have put in my idler screws. i cant get my quad to idle, and im not sure if its jetted right either. right now i have 250 jetts in it. it will run fine as long as i keep it running, i can feel the power band kick in. but like when i get on it with WOT it doesnt bog down, it just is lacking a shit ton of power. once the power band kicks in you can feel the power start to come back but it feels like i have to be in 4th or 5th WOT before it feels like i have 50% of my power back. i can be in the dirt first gear wide open and try to kick the ass end sideways and it just doesnt have the power to do it. on pavement before i could get my front tires to come up of the ground going thru every gear and that was running on one cylinder i found out. and now i fixed my cylinder problem. both fire i have compression in both. i dunno if it could be fouled out plugs... or if it has something to do with my idler screws... Maybe someone on here can help me diagnos my problem

Are you sure you installed the idle screws correctly, and are you sure you installed the slides in the carbs correctly (not mixed up from side to side or rotated incorrectly)?

 

The slides have a notch on the outside of them where the idle screws go. Take your filters off and look in the carbs and make sure the screws are sitting in the notch, after you have verified that the slides are in the correct carbs.

 

This will tell you that the slide is clocked properly and is where it needs to be.

 

 

Sounds like you need to continue to dial in both screws until you get it to idle. Start with the screws all the way out, make sure the slides are the same height, and go in with the screws from there.

 

 

250 jets sound like they would be close for your mods, maybe a little lean though.

 

First thing after you get it to idle, don't ride it!

 

Get a new set of plugs and do a plug chop, don't go playin on it until you get the jetting right.

 

 

Also go over everything and double check your intakes, tighten the carb clamps, etc to make SURE you don't have any air leaks. You need to triple check everything when you have the motor apart.

 

Another thing, make sure the crossover tube is in place on the carbs.

 

Also, throw that boost bottle over the hill before it cracks your intake boots.

i got ahold of a friend who knows his way around a banshee... i put the TORS eliminator kit on and i didnt unplug the other end of it... that was the major problem i had... its running like a rapped ape now... we put 270 mains in... new plugs... it rides a constant wheelie all the way thru 3rd gear now....

 

Thanks for the help
