Can anyone tell me what may be wrong?

I have a 1999 yamaha banshee, i just recently converted it from a twist throttle to a thumb throttle, i got it all hooked up... took the carbs off and cleaned them and rebuilt them, put it all back together and started it up and both cylinders are running but only the right one is blowing out hot air and smoke, the left one is blowing out cold air.... help me b4 i take it up to a local shop!!!

did it only start doing this after you switched the throttle?

[Yamaha4ever]

yea they are sycned.... it gets a spark and everything and starts up... but it runs like hell, the right side is running great but the left side blows out cold air and no smoke or anything, the plugs are not fouled just bought new ones... i have no idea whats wrong im baffled

yea but it had been sitting for about 7 months b4 i did this, im thinking about going to get the compression checked on wednesday and see what they say

[98_shee]

I would do the compression check, and also switch the pulg wires and see if it does it on the same side.

[locogato11283]

strange. you let it warm up even? might wanna check the compression on that bad boy.

hard to say without knowing whats exactly wrong. could be any number of things. you dont think you can pull it apart yourself?

More than likely you need too clean them carbs alittle better,not saying you didnt clean them good but its a startand only takes 20min,

[Yamaha4ever]

yea i probably will pull it out b4 i take it up to a shop, and im sure they are cleaned because i rebuilt them got all new inside parts and shit like that so i dont think that they are clogged and dirty, the left side that doenst work right blows about the same out of the pipe as the right side that does work, ive never seen anything like it lol

Check your reeds, make sure you don't have any air leaks the intake boots are bad about cracking and causing an air leak.

[locogato11283]

pull the bowl off the carb on that side and see if its got a good flow of fuel.
