Running on 1 cylinder... HELP

[cdubbz111]

Hello all, this is my first post tho i have been reading on the HQ for a while.

 

What prompted me to post was that my banshee (2001) is running rather oddly. It will only run on 1 cylinder at idle and about half way through the throttle the second piston kicks in. I am gettin spark to both pistons and gas also. I have no idea what the problem could be but i fear that if this continues there will be premature wear on the constant runnin piston.

 

 

Thanks for any input/ help

 

Cameron.

Do you have the tors Still???

more info on your elevation, ALL engine mods, current jetting settings etc would greatly help... Right now there are too many factors that might be causing the problems

I know you said you have gas and spark on both sides but I would re-check everything. Swap the plug wires around and see of the other side quits. That would test the coil and plug wires. Also clean the carbs and make sure you are getting gas in that side. If not the cylinder is not getting much lubrication and is going to jack it up. Just double check everything and see what happens. I had the same deal going on, and it ended up being a fuel problem i over looked 3 times. Hope this helps you out. :thumbsup:

Also check that your carbs are properly sync'd. I've also seen cracked reeds cause this problem as well.

you might want to try some new plugs anyway. they can have spark, but not be strong enough to fire properly. :shrug:

is your choke tube connected between the 2 carbs......easy to check and easy to forget to put back on.

Lets see, I i live right above sea level, im guessing tors are the throttle controls on the top of the carbs? and to be completly honest i dont know a whole lot about two strokes and the reed settings. all i know is there is a stage three race kit, its very possible I need to put new plugs in ive ran my quad for about 15 hrs on the same set of plugs with a rich mixture (just had new wiseco's put in.) to break it in. so new plugs will be first priority, second will be to switch the plug wires, to see if its electrical, third will be to check all hoses and connections to make sure everythings air tight. After that any suggestions? For this moment tho, im going to go sleep. Just got off work and im beat. I appreciate all the responses you guys/gals are very helpful.

I'm almost 100% sure that your carbs are not sync'd. Take your filter off and look at the slides to make sure they setting the same distance from the body of the carb and are moving at the same time.

I OWN XTREME ATV'S AND HAVE SEEN THIS PROBLEM 100'S OF TIMES. IF YOUR CARBS ARE RIGHT ON....AND YOUR REEDS ARE OK. THEN IT IS YOUR CRANK SEAL. MOST OF THE TIME IT IS THE CYLINDER ON THE LEFT THAT DOES IT. DO A LEAK DOWN TEST

Did you touched the On//Off valve?

UPDATE

 

I finally got the courage to go mess with the shee, (its 38degrees out here) the carbs arent "level with eachother, does that mean they arent sync'd then? the reason i ask is that they "float" moreless on the carbs but what i have found is the new plugs did no good, switching the plug wires altered nothing, so my next question is where would i find the adjustment nob or lever at to adjust the carbs? oh also is there a prefered air filter? ive always been partial to K&N but what would be the best application for loose packed dirt/some sand?

thanks again all and sorry for the delayed responses

ok they are not setting the same distance from the carb.

So can someone help me through the process of sync'ing them? or send me to a page that can assist me? please and thanks
