Is a P11 really that much different. Go ahead and post your Mikuni settings (if you can remember them
). It would be a good reference point (assume you had to go bigger on the jet sizes to compensate for the larger slide opening)
I have the settings around here somewhere, but they are nothing special. My P11 at the time was geared lower than a Commando, so I was on the pipe more, so to speak. Regarding the P11 being different... Major differences are motor sits straight up an no isoelastics. It's also s little shorter and mine weighs 65lbs less than a Commando. Fun bike to ride.
Another difference in this situation is the intake manifolds are not in as much of a downdraft orientation on a straight up motor. Plus, I modified the intakes that came in the MAP (Sudco) Commando Mikuni twin carburetor kit. I turned them into spigot mount and used automotive fuel tank filler hose for the connection. Probably useless info on the jetting, and totally irrelevant on this website as most of my suggestions seem to be.
This is the configuration.
This is the jetting I could find written down.
6DH3 needle, Clip in 2nd position from top.
P0 needle jet
2.5 slide
2.0 air
30 pilot
Bike was a little hard to start when cold but the cam was advanced to 9 pins between the dots. Timing was 32 degrees BTDC set static. Ignition was Boyer. I was young and slightly more clueless than I am today when I did that.
I would not expect it to work like magic, but it might be sort of close.
I've been accused of being a parts changer and nothing more here. I think that is subliminal derogatory horse hooey because I don't have a machine shop in my garage. lol
Only thing I use an AFR gauge on is my retrofit MPFI fool injected 1965 El Camino, and that's only because the kit came with software and an O2 sensor.
I've posted all this BS before. Beautifully irrelevant it is.
