Hello:

If you don't get a response on this site you may want to join the following site

www.armbell.com/kz400/index.php?mforum=kz400

There is a big 750 twin segment on that site and a number of 750 twin owners who might be able to steer you correctly.

thanks i appreciate that..

Mine's a B4, and I screwed with the carbs a bit but never ran straight pipes. Here's my first guess:

1) go with a #50 pilot jet

2) try a 135 main jet (maybe higher?)

3) put the needle clip in second notch from the bottom (one rich)

The pilot jets are the standard BS30-96 you can get anywhere, the main jets are very rare but I found one place:
