nickleo373 wrote: Hey everyone. Last week I adjusted the float heights on my 81 KZ550. The previous float heights were causing gas to overflow into the cylinders and air box. I adjusted it to 18.5mms and put the carbs back on the bike. Now it idles rough and dies when I give it throttle without the choke on. When it idles the rpms are really low and it misfires. Does anyone know what's making it do this?
Thanks
Would suspect leaking float valves were causing the overflows, and that the overflows were largely unrelated to the float heights.
Would correct the float valves, and re-adjust the float heights, using the clear tube test method.
Good Fortune!

They open and close depending on the height of the float. Make sure the seat and tip of the valve are not worn.

Because these float needles do not have a clip on them that holds them to the actual floats (like most others I've seen) the needle just falls in and out of place. So what you are seeing is normal.

If the fuel needle has a ring aroud the tip with a noticeable ridge, the needle and seat should be replaced.

Good question! Here's what I use. A little modified to JIS screwdriver bit in a socket with a 1/4" ratchet. A mirror helps so you can see the screws as you seat the bit. Ed
