1978 kz 1000 A2

How long did you let it idle in your garage? These are air cooled engines.

I started it yesterday and after it got warmed up it was smoking like a chimney. it was white smoke and it was very thick. i was just wanting to now where to start. It starts fine but it idles a little rough. i was just wanting your opinions on where to start before I tear in to it myself. I do have the technical manual form Kawasaki but i think you guys are smarter. I appreciate all the help!

Ya might just be surprised before it's all said and done :woohoo:

As was suggested, check for gas in your oil. It may be just that simple.

Well I got the smoking issue resolved. I believe it was a little oil in the gas. It has stopped smoking. It was still running rough and not wanting to idle. It hesitates on acelleration and cuts out and back fires. So I took the carbs off and cleaned them and the air filter, and the plugss. I also did the mechanical adjustment because 2 of them were not at .7 mm adjustment. I put it all back together and it still does the same thing. It runs somewhat smooth until you accelerate. I need some help. Please. I Dont have baffle either.

Has the clear tube test been performed on each carb? If not, the fuel level may be too high, regardless of the dry-measured float height.

Good Fortune!

Have you looked at the points, checked the gaps ?
Maybe the advance is giving you some trouble.

Sometimes when it idles it will almost stop and make a metallic click and then start running again.I think it has electronic ignition. It does not look like points.

If it's old and has some miles on it,the valve seals may be shot,especially if it has been sitting for some time.

I would check the large round 'thumb wheel' in the middle of the carbs at the top -- if it's not idling, screw in the thumbwheel until it does.

It's very easy to turn that thumbwheel and get exactly the same 'won't idle'/mechanical clicking noises' symptom.

I have a '78 Kz1000A2, I know *exactly* what that mechanically noisy sound sounds like, so does everyone here on the board, it's the "pre-stall grinding" noise that you hear right before the engine stalls, and is not a big deal, just turn in that thumbwheel and get it idling.

Now, if by turning that idle-set thumbwheel at the middle/top of your carbs, you can only get it to keep running at, say, 2000rpm but no lower, you may have a blocked pilot jet in one or more of your carbs, it's *easy* for them to get blocked.

I would search this forum on "pilot jet" or "pilot jet clean" and find a prior post that explains how to clean the pilot jet and the rest of the carb -- the pilot jet is the part of the carburetor that helps the engine keep running at idle.

YOU CAN SEE THAT BIG ROUND IDLE-SET THUMBSCREW AT THE TOP-MIDDLE OF THE Kz1000 CARBS HERE, RIGHT NEXT (TO THE IMMEDIATE LEFT and AT THE TOP OF) THE 3RD CARB THERE, IT HAS A + IN THE MIDDLE OF IT

well after all this help my kz is runnig really well. it still has some backfireing issues on deacceleration and warmup. I do not have a baffle. it has a kerger 4 into 1 on it. i thought about trying to put a better jet kit on it. Any suggestions?

Have you checked the vent from the head to the small filter/vent on the engine mid point under the carbs?? If that vent is blocked or hosed kinked ,it will cause back pressure in the engine.

Slightly enrichening the pilot circuits may reduce the exhaust popping on deceleration.

Good Fortune!
