Rght side cylinder problems

[ghostryder420]

I have a 2006 banshee with pro circuit pipes and V-force 3s and a pro design air filter with no lid. My right side cylinder doesn't seem to idle very well. At idle and a little bit above idle its not firing nearly as much as the left side. The left side exhaust pipe will have a healthy amount of smoke coming out of it and I can feel steady pressure if I hold my hand up to it. The right side exhaust has very little smoke coming out and very little pressure. When i raise the rpm's a little, the right side will get choppy but it clears up the more I rev it. As i ride it seems to be fine as long as my rpm's are up but it has the occasional backfire. I have checked out my carbs and they seem to be in synch (as far as I can tell with my eyes and ears). I have taken both carbs apart and cleaned them out, but I think I'm gonna clean the right side carb again just to be sure. I have not done a compression check as of yet, that may be my next step, but if I had a compression problem, it would affect the engine throughout the entire rpm range, right? Please help, any advice would be appreciated. Thanks.

 

P.S.- When I let the bike idle to warm up for a few minutes, the left side exhaust will get hot as it should and the right side will barely get warm to the touch. The right side won't get hot until I ride it and raise the rpm's.

Did you try swapping the plug wires to see if the problem moved to the left side?

have you adjusted your jetting?? I'm not sure what the stock main jet is but I had a 290 in mine before I bored it out.

unless u already have try riching up the air fuel screw on the side of the carbs its a brass screw the only reason it should be backfiring is because its too lean no if u had a compression problem it wouldnt stay the same throughout the RPM range at higher rpm it would have more compression because the rings are being pushed harder against the cyl. walls creating a better seal.

I'm having the same problems mentioned by ghostryder. We were trying to troubleshoot the problem tonight and we did switch the wires from one plug to the other and this resulted in the left side firing improperly. Initially the right side exhaust is cool and firing improperly; switch the plug wires and the left side mimics the same problems the right side exhaust/cylinder was having. We were thinking it might be bad coil, but I can pull the plugs and check the spark and either plug and they both look bright blue and fire with every kick. Any suggestions are appreciated.

 

Thanks

Kilroy unscrew the sparkplug cap and cut the sparkplug wire back about 1/2" and screw it back in. Do the other side as well.

 

Ghostrider pot head take the right carb off and unscrew the pilot jet and make sure it's not plugged. Hold it up to a light and you should be able to see through it. If it's clear than make sure both slides open at the same time and have about the same amount of opening when the bike it at idle. Make sure the air screws are both turned out the same amount of turns.

Thanks, will do!

if its not in your fuel bro check your compression on that side....could be a ring

Fixed the problem! A dumb oversight on my part :/ When I reassembled the bike I forgot to reinstall the choke crossover tube. I cut a piece of fuel tubing, put it in place and the bike kicked over and began to idle and hit on both cylinders like it should. Also, one of the spark plug boot ends was a bit loose so I trimmed up the wires and tightened the boot ends back in place. Thanks for the input guys.
