Unless they are completely clogged, seafoam may work to kick it loose. There are ways to prevent the gumming up, I drain the carbs and line completely at the end of riding season, no fuel in lines or carbs, means no fuel to gum up. You can clean the carbs and then allow the same issue to reoccur the next fall if you don't take preventative measures. I've made it eight years so far without touching my carbs. YMMV

Do you think I could drop the bowls for the outer 2 carbs while they're on the bike? I have an angled screwdriver to reach the inner screws.

With out it, you rely only on slow jet to idle and to about 1/4 turn of throttle. Clean them good. Not hard to do.

If it idles only with choke on and revs only with choke on then carbs need cleaning. Has bike been sitting for long time? The fact that it only idles with choke on tells me carbs need cleaning On Fri, Aug 24, 2018 at 12:05 AM Harold Peters <[email protected]> wrote: I would suggest looking at the breather boots where they join the air breather box.

Are there any areas known to leak vacuum on 92-03 Nighthawk 750s?Thanks,Daniel -- You received this message because you are subscribed to the Google Groups "Nighthawk Motorcycle Lovers!" group.
