I took a couple high speed passes yesterday on my '96 ZX-9. It was running great, never missed a beat, even at an (indicated) 170+ mph.

Today, I took it out for a little cruise around town and noticed a new noise. Sort of a high pitched whine, definately engine related, not transmission.

It sounds ...

That depends on how long you plan on riding "before you get it fixed'. if you mean a week or so, it should be fine. if you're thinking that you're going to get the rest of the riding season out of it, I wouldn't.

On a similar note, I had an '84 Honda VF700 that had a front wheel bearing 'issue ...

The tank was drained, then the motor was fogged, then the carbs were drained.

I'm curious as well. I live in an area where all of the traffic lights are triggered, not timed, so I could sit there for wuite a while until a car pulls up behind me to trip the sensor. On occasion, I've even gotten off the bike, walked to the side of the road, pushed the pedestrian button, walked ...

I did in fact check the float levels...within spec. Made a slight (very slight) adjustment.

Choke operates properly. Returns to full off position properly, without any sticking.

Although I'm new at this particular carb setup, I'm not new to carbs in general. I'm honestly stumped.

I did the carb ...

The key to a good 2-up ride is communication....I don't mean talking about it before you hit the pavement. I mean an intercom. It makes the ride much less rider dominant, and much more a 2-up experience.

I used to do most of my riding solo. Then there was a wife and kids, and the solo riding was ...

See, that's the problem. At idle, it smells like it's running rich, but while riding it, it seems like it's running a little lean. The idle mixture (I think) is rich if anything, but the transition is lean.

At his point, I'm thinking it's trial and error.

Is there a idle mixture adjustment screw on these things? I was under the assumption that the screws were plugged. As far as I can tell, it appears to run rich at idle already, at least is smells like it.

I did inspect for vacuum leaks, and everything seems fine. I did just recently replace a ...

Twice, just to make sure.

I'll admit that the carbs being out of sync might produce the symptoms I'm seeing.

I'm not very familiar with this particular model of carb, but it seems like the transition circuit is clogged (if these carbs have that circuit).

Hello all,

I've been working on this one for a while, and I'm out of ideas.

I have a '96 Kawasaki ZX-9R (900B3) with about 12000 miles on the clock. It's been trouble free for the years that I've owned it. Recently, I noticed a slight miss when running at part throttle. RPM doesn't matter, it ...
