AnyOne have easy float level Check?

Any good Ideas on how to check float level on stock 77 KZ650 carbs? Quick way. or Correct way? 2-3 mm from mating surface? Clear tube somehow attatched to the drain holes.?
Start by making sure the pet-cock is closed. Drain bowl and hook up clear hose ??? and hold up by the carb turn back on pet-cock and wait till fuel stops filling in the tube, measure level to the mating surface around 2-3 mm???? Check the other three the same way with the bike on center stand????? What do I use for a connection from bowl to tube??????

You pretty much have every thing correct but here is the connection you need. I'm gonna get me one!

Hi mzandmz, this is the higher cost alternative.



This is where I got mine Link

Best of success.

Others have reported using a plastic vacuum fitting from the auto parts store. They just screw it into the drain screw hole, cutting new threads on it. Any leakage would probably be minimal or insignificant. Or put teflon tape on the threads.

Thanks for picture and location of where to find tool.

The end of a proper size (outer diameter) soft plastic hose will itself "thread" into the drain screw hole. Without needing anything else. No device, no barb, no nothing.

Is quick and easy, and with minimal or irrevelant leaksge.

Perhaps a good hardware store or hobby shop.

Good Luck!

Do you check all four at the same time????If you want to

I just check one at the time. Because of needing to hold the plastic hose so very still and steady against side of the floatbowl during the "filling and reading" part of the test.

Besides, I only have one hose. :lol:

Good Luck!

Thanks,I guess it doesn't matter,it sounds painful any way you do it. Drain,tube,fill,drain,adjust bla bla bla on to the next three......

"Checking" is relatively painless, compared to "adjusting."

If done with carbs on the bike, I perform the test outside on the driveway, with a shop towel under the carbs to catch and soak up any gas spillage.

"Adjusting" is for me a carbs-removed-and-on-the-bench procedure. And testing each successive float tang adjustment with carbs on the bench.

Only need one floatbowl screw during testing.

And even this float tang adjustment procedure is best done on an outside table, imo, with carbs preferably "downwind."

Once set correctly with proper tang adjustments, the levels should remain good-to-go, indefinitly. As there's nothing to interfere with the adjustment following re-assembly.

Good Luck!

The guy I bought if from Had rebuilt the carbs and told me they need sync.But I dont know if he properly adjusted the float levels. Time will tell,that is when I check them out.

Would concur with verifying fuel levels before synching or other carb adjusting.

An otherwise perfect carb will suffer from incorrect fuel level. Too high = too rich. Too low = too lean.

Hopefully, the rebuild was competantly done and also included correct float heights (easily verifed with carbs on the bike by using the clear tube test).

With a good sync being the final touch.

But wondering why anybody would rebuild carbs and not sync them. :huh:

They all say that. :laugh:

Good Luck!
