I was reading a thread on carb tuning that John Connolly of aircooled.net was on and he suggests a much leaner idle/cruise AFR than what I've been running. I've set a target of 12.5-13.5 in that range, but he suggests you can go much leaner than that.
This may also explain why Jake thought I was nuts when I went from a 60, to a 62, and then finally a 65 idle jet on my 40 Dellorto's. Does anyone have any real world insight on this? I've loaded in my 60's for a ride tomorrow... -Aaron |

I run both an LM-1 for AFR and a temp compensated head temp sensor. I know that 12.5 - 13.1 is great for WOT, especially considering we have some ethanol in our fuel.
What I'm interested in is cruise and idle... Look around for "Dellorto idle AFR" and you will probably start to see what I'm seeing. -Aaron |
