Couple issues.... One, curiosity, are Keihin carbs stock on a 2001 Bandit 600S? And two, anyone experience bog until 7000RPM? I know the power doesn't kick in til then, but its pretty bad, hard to cruise at a decent engine rpm. I want to clean the carbs, but should I do more than clean them? I know there's rejetting and shimming the slide pin, but that's usually after modding it. I'm keeping her stock for now. Any input would be great.
