Is the bike stock? done any mods? did this start recently? do you have good gas in the tank? did the bike sit for a long time?

Too many variables at this time to give exact advice, but I'd start with the basics..

My bike has head work cams ect, runs 100 octane carbs have been in and out. The bike straight piped have had no problems for long time installed a baffle to tone it down. Bang ran like crap. rejet no diffrence cut out baffle. rejet again still there runs awesome as long as you ease into it. Hammer it feels like runs out of fuel but plugs are light brown, I am at a loss.

With all the work you have had done on it I'd suggest at this point you'd have to hook it up to a dyno and find out if you are running lean or rich when you slam it open.. The plugs don't always tell the whole story.

Some of the more knowledgeable members might have other suggestions though.
