Question about intermittent engine noise.

[acp]

The best I've had so far was 93.4 miles out of the whole tank. Then it cut out on the slip-road off the motorway

Luckily I coasted to the top of the slip road and just had to push it over the roundabout, then 20 metres down the hill to the petrol station.

Re: Engine noise .intermittent

The carbs are 34's not 32's and the bike does run rich.Fuel consumption is higher than it should be. I only get around 28 mpg max.I believe it should be better than that. I am planning on getting the carbs rejetted and synced soon,as soon as I get the cash together and I find the right mechanic to do it here around the Greater Cleveland area. Its tough to find someone who is really interested in doing a proper job. I would be interested in knowing what fuel milage other zl 900 owners get. My motor is stock except for the cobra pipes and 34 mm carbs. Before I start messing with cam adjustments I'll get the carbs done and synced. I wonder if it would be worth it to have the exaust gas analysied? // I have a set of Dyna coils for the bike. I have talked to some mechanics who said don't bother putting them on that the stock coils are fine. But, I believe a higher voltage spark would have to improve starts and performance. I just have to come up with a practical mounting bracket for them, and provide enough clearence for the zl 1000 tank. Any more comments would be appreciated,thanks for the help. I will be sending pics of this bike. It is special. The engine has been polished out and the bike has a tracy street fighter bikini faring that looks really good. The fairings are no longer made and I have not seen another one like it.

I would make sure the valve adjustment is in order and the ignition is healthy before trying to jet it.

Cleveland? I know i'll be meeting you this spring in valley view. Look forward to it.

I'll go with Mark on this one. Fuel consumption sounds a bit high, but weak ignition could cause that as well as jets, and ignition parts are a tad cheaper. The valve adjustment isn't all that hard, and the ignition pieces are fairly straightforward as well. You'll either get lucky and fix it by accident, or have a rock solid engine to go with your fresh carbs. Good luck with it!
Later,
SS

I have an 87 zl1000. After I had the valves adjusted and the carbs gone through, adjusted and synced up, I get 32-35 MPG. Before the adjustment I could smell a gas odor and it was running rich. Carbs have stock jetting and the engine is all stock.

There is a Kawasaki dealer in Elyria OH, that will work on these. At least say they will. I called them when I was trying to figure out how to do some stuff to my 86 ZL600. There website is www.kennedyscycles.com
