I have a Wideband Air fuel gage and have been adjusting my MPS. When I was tuning injected motorcycles I was shooting for ~12.7:1. What numbers do I want to shoot for in a 2.0L FI D-Jet runing regular fuel.
I was thinking that I want to keep the numbers setween 12:1 and 13.5:1. I have hear that >14:1 is to lean. |

Avoid hanging out in the 14.7 - 15 - 15.5 zone (this is the death zone). One can go leaner when under part throttle cruise as high as 16-17 and see lower CHT's but only if your using a vacuum advance distributor. If your using a centrifugal only distributor shoot for 13.2 (+-.5) across the board.
This chart shows how CHT's and AFR & vacuum advance work. The dashed line in the middleis 14.7 stoich  |
