2000 stock banshee, attempted rejet, need help

[Eddie]

Hello, i've recently purchased a used 2000 banshee. after doing a little maintanence on it i decided to start tuning, although i am completely knew to the whole quad let alone dual carb engines, i attempted to rejet it. after taking my quad quite apart and learning the main is not a needle but a part you must purchase to change, i decided to only change the needle setting. so after setting the needle to the second clip, and having a few issues with figuring out how the valves fit back in place i started to reassemble (was this a bad idea?). after reassembling what i needed to have it run, it wouldnt start, i checked all the fuel lines and spark plugs, i decided to manualy prime it. This happened to work but now the idle is running very radicaly, the left exhaust is pouring out thick smoke in a steady stream while the right side is running as it should be in a regular tinny, two stroke way, and after playing with the idle screws and air pilot screws not much has changed. Real new to this stuff any help at all would be appreciated, id love to learn to troubleshoot myself but the instruction manual is how can you say, vague?

Mods? Pipes, jets, mains and pilots? Why did you mess with it? How was it running? Temp where you live? Elevation? Buy a clymers repair manual, read the the jetting FAQ's in here and answer the questions I asked. We'll get you up and running.

When you adjusted the c-clip height, the two screw retainer was removed. It does matter how it goes in. The groove of the throttle slide should face the cable groove of the retainer when you put it back together. Thats' important. The rotational orientation matters.

only mods i have added would be a K&N filter, orignal pipes, orignal main jet pilots, the reason i had decided to change needle position was because of the extreme hesitation i was recieving at 2/4 - 4/4 throttle, it was running alrite (other than the idle being slightly low for the temperature), the current temp is averaging around 2 - 8 degrees celcius, elevation im not quite sure of, i live in alberta, canada if that helps... and thank you for the reassurance its nice to know i can get help without having to pay big dollars, and learn at the same time

thank you i will go take a look at that right now and post as soon as i correct/confirm its positioning

hey thanks for the tip on the valve, it turns out one of the valves did have the cable holder in the wrong way, although after correcting it did not solve the problem, the engine still seems to be running richer on the left side and the right seems to be sputtering as if it is not drawing any fuel in. I have had to prime both sides manualy is this normal?

Are the carbs in syncronization? Also, did you replace the choke crossover

tube between them?

Yes that was the problem thank you very much, it seems though that i cant seem to fine tune it properly, i followed some of the synchronizing instructions and set the idle and the cable tightness, but when i throttle now from idle - 1/4 it seems to stick and wont idle properly i was wondering if someone could tell how what to set the pilot screw to, i have a 190 main, and the needle clip is set to the fourth notch down, so fairly rich. everything else is stock other than a K&N filter i recently added, oh and lets not forget that the retard who sold it to me forgot to give me the snorkel so its missing that as well. If there is anything else that i should be reporting about my quad that would help with pin pointing this problem please ask, thanks again.
