Ok so I have a 96 900, TBR Full Stainless Exhaust to carbon can, jetted, and k&n filter. My bike starts smoking after it warms up. It doesn't smoke at idle, just when I open the throttle a little bit. This just started after running it the past couple days in the driveway. I was running on 3 cylinders due to a stuck float. I got the float in working order again and replaced the plug that was in that cylinder. It runs great and has good throttle response. I have also done a compression test and got even readings all the way across the board of 180. I changed my oil and the level didn't drop at all, nor was there fuel in the oil, or coolant in the oil. The smoke is a tint of blueish white but stinks like it is running rich.

Could this be all the raw fuel that was getting dumped into the cylinder when the float was stuck, just finishing burning out? When the float was stuck, the number 3 carb was literally dumping fuel into the cylinder.

I have not ridden it on the street yet this year, but figure maybe that'll burn out the rest of what could be in the cylinder.

Thanks in advance for any help.

 

Also wanted to add that this is the first time it has smoked since I have owned it. When I put it away for the winter it wasn't smoking and everytime I rode, it didn't smoke. The smoking didn't start until the float was stuck. This is what is leading me to believe that the smoke may be coming from whatever is still in the cylinder that hasn't burnt out yet.
