[QUOTE="indianakid, post: 204979, member: 5044"] I would like to propose a hypothesis that the hesitation is caused by an over rich condition. Assumption 1.. The bike ran fine before the prolonged sitting event. Assumption 2... The bike idles fine and runs strong above 3k. And this over rich condition could be caused by a stuck power valve. The power valve does not affect the idle circuit. But a stuck pV and a working accelerator pump will cause an over rich condition coming of idle resulting in engine stumble. Above 3K the mixture will be richer resulting in a strong running engine but high fuel consumption. So my suggestion is to check the power valve. Best of luck ! [/QUOTE]
