On the bikes I've tuned / worked on - Around 12.5:1 is good - maybe up to 12.7:1

Only problem is that the only way you're going to get a good and true reading is with a Wideband (heated) sensor.. The other sensors just don't get hot enough to give a good and true reading that is repeatable..

That's my $.02 worth on it...

I've fiddled with the Power Commander on EFI systems where I did not have access to altering the programming directly in the ECU. The PC is not a bad system when it's the only tool you have to use..
