so i figured out what the problem was with the banshee. it was electrical. one of the spark plug caps wasnt getting good connection. so i repaced the caps, and trimmed the wires back... what a difference, i cant believe how this thing rips!!!! thanks everyone for the help and suggestions.

So do not plug the hole. i have the hole plugged right now so i will have to flip the throttle cable holder around. another question for ya... when synchronizing the carbs when the two indentation marks line up in the windows on the sides of the carbs, but i still have more throttle to go so they go beyond the windows... is that good or bad? the only way i can think to "fix" that is to screw the throttle limiter in to shorten the pull.

I noticed on the tops of the slides when you pull them out of the carbs that there are 4 holes. two for screws, one for the needle and what is the other hole for? im not sure if when i put the piece back in that hold the needle in place if im supposed to cover the hole or not?

ok, so new boots... same damn back firing at about 1/4-1/2 throttle... i cant believe what a POS this thing is being. following jetting directions to a T... i have two more options before i watch this thing burn and bring the metal to the scrap yard.... would definately rather watch this thing burn than sell it to someone who flips a preverbial switch to make it run like a top in 30 seconds... WTF!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

So Im 90% sure i figured out why my banshee has been giving me such a hard time with the jetting! i sprayed some more carb cleaner on the reed side of the carb and when i did, the idling dropped by about 50% didnt matter on which cylinder. upon further investigation i noticed that the boots were cracked terribly. i think all of the carb adjustments are what really tore them up. taking them on and off about 25 times... there was some old silicone on the boots. so i tried to use some more silicone after i cleaned the boots up from dirt and grease. that didnt work, so i ordered some boots and they will be here soon. hopefully that is the last thing i need to do before i can see what this banshee is all about! i will keep you all posted

Hey, I feel you pain about having a fresh rebuild and not having it run right. i have stock carbs and talked to someone and they told me my pilot jet was too small at a 25, they suggested 27.5's. sorry im not of more help, im waiting for my jets in the mail and my individual filters for the stage 3 kit. which is having the opposite problem as yours... runs great down low, and 3/4- full throttle she spits and sputters... good luck!

ALSO i checked for air leaks and didnt come up with any. hopefully someone has some ideas because i dont want to blow this thing up seems how it has 4-5 hours on a fresh motor....

so this morning i started messing around with the carbs. I got rid of the low end pop by turning the air screw in 1/2 turn so it accelerates great until just before red line then it starts hesitating. the troubleshooting guide that came with my jet kit says that would make it a rich condition. im not running the air box lid, so when i put the lid on and rode it, it didnt have hardly any power. so im wondering what should i check next, the needle which is on the 4th position, or drop one size Main jet to a 270?

so i just installed my TORS removal kit, which makes working on the carbs POSSIBLE. Then i installted a stage 3 jet kit. i am not running seperate K&N filters, just one K&N with the air box lid removed. it started after a few swift kicks idles great! took her down the driveway and when i stab the throttle down low it back fires once then clears up and seems to be running much stronger than before. I had 210 main jets with the air screws out about 2 turns, i have installed 280 MJ's with the fuel screw out 2.5 turns. it got dark out so i am waiting until the morning to see what i can come up with. as far as carb jetting goes, i only really know what the directions tell me. the needles are on the 4th groove out of 6. let me know if you have any other questions. it seems to do the same thing in every gear quick back fire(stumble) and then starts SCREAMING. jet kit was well worth it IMO. feels like it has wayyy more power. please let me know what you think

hello everyone, im trying to find a lesser expensive graphics kit for my yamaha banshee. i am not looking to spend too much money, unless i see the right kit. could someone please point me to a website or two? i have looked at CEET and didnt particularly like any of those. thanks for any replies

hello everyone again. so i changed my chain and sprockets and i got a 41 tooth rear sprocket so i had to adjust the chain to make the chain work. now the problem is that i adjust the chain the way my haynes manual says. which consists of jacking the wheeler up, and making sure there is roughly .5-.75" of slack measured in the chain. so when i get that and sit on the machine, the chain is way too tight. so like a dumbass i took it down the driveway and when i got back to the top it was loose. so it appears to me that the pinch bolts moved enough to make the chain have some slack. so i re-adjusted and re tightened everything(tighter than before) and the same thing happened, but not as bad. also how accurate are you supposed to get with those adjusters, after fumbling with it for and hour (my first time ever with this awesome setup...) i put a tape measure on the carrier and measured, they are different by a heavy 1/16". I guess i didnt learn nothing because i was unable to tell which way moved the adjuster in and out. someone please help me!!!

so i just got my 91 banshee running after a complete rebuild. first time i ever rode it i noticed how spanked the front shocks were. i know people say they are harsh, but i find them down right SOFT, way too soft. so im looking into putting something else on there. i also have a 400ex with 450r shocks on it. so im wondering if a set of 400ex stock pogos will fit. if i didnt give my old stockers away i would definately have checked them. so i just want to know besides yfz 450 shocks will fit?

Hey! Guess what?!?!? I changed my mind about the boost bottle! LOL. maybe perhaps some reeds!? i am running the stock reeds right now. they looked like they were in great shape. but thanks for all the replies!
