Help 97 cb6 600 f3
 

I just got a cbr 600 f3 1997 got it running good some times runs ruff but that's the rest of trash from the tank but what would cause it to blow smoke that smells like carbon build up plug maybe burned out?

Sounds like burning oil to me. Or bad gas. Coolant smells sweet and has a blue tinge. If it smells like gas, it's lost spark on one or more cylinders
