Mk1 turbo bandit af ratio

[Alex]

Hello all. I have a bike that runs 12-13 all the way through the Rev range (road use) what af are you guys running  on your turbo bikes? Have been told that 11-12 is better on these. Thanks Alex.

IMO if the figures are accurate ie. its a newish sensor, I'd say its spot on! Still rich enough to be safe - max power is normally about 13.2:1. On carbed bikes its difficult to get accurate AFR numbers without lean spikes - using 11-12 AFR's gives comfort zone but isn't ideal. This is where EFI scores big.

Yep you will be fine at that, just keep an eye on it so that it doesn't go any leaner.
