Hi ,
Your bikes engine is running too rich !! , you will have to set the air-fuel mixture ratio.
Try to check the air filter it may be too dusty and kinda clogged thus not allowing air to go in.
If all is ok thn you may have to clean the carbs and reset the float in the carbs.

Spark plugs foul immediately


Fouled plugs may be caused by oil leaking into the cylinder. Does it smoke when running (cold), are you using up the crank oil. Black smoke is excess gas comsumption, blue smoke is oil burning. If your plug is fouled with black carbon, you are most likely running to rich.

Tractor running rough and black puffs of smoke come out exhaust pipe when you rev up engine. What should I try?


Normally black smoke indicates too much gas or too much choke. Remove and clean or replace the spark plug because it is probably fouled. Change the air filter because it is probably clogged. I am not sure how mechanically inclined you are, so if you are then it needs a tune-up. If you are not then I would take it in for a tune-up(needle valve replacement or cleaning and adjustments, float bowl cleaning, and spark plug replacement.

Harley Davidson street glide idles low and sometimes dies at stop signs?


Possible cause is a crack in the fuel filter shell which is installed inside the fuel tank. Harley has a recall for affected models. Post your VIN number or go to your local dealer and ask him is there a recall for your bike. All he will need is the VIN number and any recalls will be done under warranty. By the way, not sure of the year of your bike but it may still be under warranty anyway. Other than that there could be a TP sensor fault.
