How will I know when my bike loses a carb?

Yep, just ask Hildo...

Thanks all. Yea, I just want to see/hear/feel what it sounds like so I'm able to start troubleshooting before I get on here. I don't want to be driving along like some fool who doesn't know their own bike.

Course you're probably right about the big change. It's nice to go screaming down the highway at 70 and be barely breaking a sweat (6000 rpm) so I'll probably notice it quick. But still. I'll toy with it this weekend then.

Does this sound right?

After cleaning my chain today, I decided to try your recommendations out and here's what I found. First off, I didn't try to ride after this but I did give it throttle on the center stand to hear things.

With one plug off, the bike will still start but there is some definite hesitation (more so if number 2 wire is off than number 1) and it takes awhile to fire up the first time.

With two plugs off, the bike will not start at all.

So, in my mind, I could still run on one cylinder being down but with more than one, I'm not going anywhere. Sound about right?

You spot on Scott, you can limp home on three pots, but if you loose two, call a buddy with a trailer or a bakkie.

Six grand at 70 in top gear?? Those stock sprockets (or equivelent to) as far as tooth count? Most of the GSes I've had are not even or just spinning 5K at 70 in top gear. And yes I realize it's a 550, and yes i realize it's got 6 speeds.

Yes I'm running stock - 15/50

Riding down the highway 70MPH and engine died out.It will will nfire on starting fluid for a second.Fuel does come thru the petcock when I turn the starter.Could the carb jet clog all at once?It was running great.

Iceman, you should start your own thread so people will see it and respond faster than to this one that really doesn't coincide with your issues.

With that said, what maintenance have you done and is your electrical system up to snuff?
