Dominator is high flash point. There is a good chance that can be part of it. I wonder if you are in a rich carb condition. Jetting is super easy on these bikes. You can change the pilot and main and needle without taking the carb off. Just unscrew cap and loosen boots. Twist carb bowl towards you and service. Simple and cheap jets cost less than $10 each and even though it runs nice it probably needs it done. Not sure where that chart came from but the flash point for interceptor is way wrong.
