And out of curiosity, are you checking the spark plugs after you take it out for a run?
The mixture screws mainly affects the pilot circuit. On a KZP the starting point should be 2 1/2 turns. I cheat and use an o2 sensor to fine tune mine. They end up at different settings but are in the general ballpark of each other.

Did you weld bangs in each pipe? That would be very smart. More details please.theApehouse wrote: I cheat and use an o2 sensor to fine tune mine. .
I was adjusting Power Commander map on Harley with O2 sensor.

Yes, exactly. I had a friend install 1 on each pipe, right outta the head, maybe 8-10 inches down. It ruins the shiny mufflers and looks totally Frankenstein-ish, but I purposely left my old KZP all rode beaten and worn(like the old Blues Brothers mobile). It's a great running rebuilt machine on the inside, but you'd never know it by looking at it.
I plug a wideband sensor, one pipe at a time, and use an Innovative LM-2 to read. I love it. I can also mount the reader on the handlebars and take it out for a ride and see exactly how it does at all precentages of throttle. The trick is, IMHO, is not to get caught up on the numbers too much. If it runs great, and there's no major red flags, just let it be. And ride the heck outta that thing!

Super!!! You can choose perfect jets! You can drill holes in bang plugs and install some chrome covers.theApehouse wrote:

I believe it depends on the application. If installing an o2 sensor to give constant info to an ECU or FI system then a single o2 sensor in the 'communal' exhaust stream is the way to go. I wanted to be able to read each cylinder individually, and the general rule of thumb is, as close to head as possible for most accurate readings. If mounting an o2 sensor that will stay in the exhaust at all times, the trick is to make sure it isn't in a position where it won't collect condensation on it.

As i understand it, yes. On a horizontal run 10-2 is suppose to be best spots. On a vertical section pointing down so nothing settles on tip.
