Default 97 EVO fluttering sound

1997 Stock EVO with a Mikuni 42. I just noticed this now that bike is running better. ( bad VOES).

When i let let off the throttle right before the engine gets back to idle I can hear like a fluttering sound coming from the carb. What is that? Does it every time. Not loud but enough to where I can hear it.

Without actually hearing it, my suspicion is the movement of the slide.

I would have to agree with Scott, it is not an uncommon thing with the mikuni, and if it is slide noise it is nothing to worry about. Just confirm that thatnactually is what you are hearing to be on the safe side.

10-4. I don’t know how I’d check. Because if the filter isn’t on the bike, the carb won’t stayon
