If I eat a lot of spicy Mexican food I know this helps stop the gas coming from my tailpipe.

smokey unburnt race fuel? bad coil causing the blowing of unburnt raw gas out seems possible but unlikley

Had the same problem with my CBR, check the fuel pressure regulator. Mine had ruptured inside, letting gas get sucked back through the vac. hoses, SUPER flooding out 2 cylinders and blowing it out the tail. It also, obviously ran like poo!

Had that happen with a bad fuel injector. It ran like crap too.
