I bought a KZ750 a little bit ago to fix up and found it was missing the plugs that cover the pilot jet in the carburetor. I think I saw somewhere on the forum that the height of the plug is important to ensure it doesn't come loose in the carb bowl. I've decided I am going to just machine the plugs out of aluminum because I can't find them anywhere online and I already have the seals for them. Does anyone know, have, or can get the critical dimensions for the part?
What about modeling clay to judge how high the plugs should be? Stick a chunk over the pilot jet passage, then install the float bowl and tighten it down. All other dimensions are easy to determine based on the carb and O-ring.
BTW, brass might be a better choice of material. It won't corrode as fast as raw aluminum.
This may not be much help. DoctorRoboto may have the dimensions but hasn't been on the site for a number of years & I'm not sure if there's an email address for contacting him. He made copies using a jeweler's lathe, so the float bowls help keep them in place. From his comment, apparently there's a tang or something on the bowls.
Also, there's an image of an oem cap 11012-1128 on the internet being measured by someone else using a digital caliper: length is 14.7mm.
I have a 1981 Kawasaki 750 LTD, I had the carbs apart last month and took these measurements as I was considering making some plugs for my carbs. Keihin CV34
sorry for the sloppy sketch, I never meant for these to be shared ,let me know if you need further clarification.
measurements are in inches.
also I need a left and a right fuel bowl if anyone has one available, Thanks
