That is a classic symptom of a vacuum leak, not sure but could be.pazzadelivery wrote: I have been riding my KZ750 for a few weeks now, but it has a few problems with start and idle. When I get it started the idle is really high, about 3500 rpm.

I have cleaned the carb out thoroughly, but from what I have read online it seems like one of my carbs is delivering much more fuel/air than the other. How do I adjust how much each individual carb is sending into the cynlinders?
You first do mechanical sync where the throttle bar is adjusted so both throttle butterflies open the same amount. You use a precise rod like a small drill bit to see if both are open the same amount very near to being fully closed where the bike idles.
The idle screws on the sides of the carbs adjust richness. gently turn them into bottom and then open about 2 turns as a starting point.
BTW: if you have the BS-38 carbs, increase the pilot jets to size #50 and the engine will run better. Stock is typically 45, but 50 will run better.

That's a definite sign they need to be replaced - same thing happened to mine when my old ones leaked. Unfortunately Kawasaki has discontinued them, and I don't see an aftermarket equivalent on Z1E, so I suspect eBay is your best bet for new old stock (NOS) ones. Below is the Kawasaki.com diagram for the 1978 KZ750-B3 twin; it shows the part number. An eBay search using that part number did show some parts being offered (see link). Ed
