My ST1100 has developed a miss from just off idle all the way up through the RPM range. We have synched the carbs with a SK Flowmeter, changed spark plugs (NGK Iridium), changed fuel filter...and still a misfire/stumble persists. It is most noticeable just off idle with light throttle. It misses all throughout the RPM range, worst under light throttle. The bike has good power and accelerates well.
The bike has a K&N air filter, but I don't think it's a factor since it ran like that with the air cleaner off synching the carbs.
The bike is a 1996 ST1100ABS with 31,500 miles.
I am thinking it may be a vacuum leak. Where do I begin to figure out where?
