of to track weekend so took cossie for 1 last spin to see if all plug in lm2 afr meter and while on full load/throttle was reading 10.8 -11.5.
i thought that was to rich?
can someone please tell me what i should be seeing on the afr meter while flat out.i thought it was 12.1
on a consant cruise i see 14.1

cheers mark

 

At full load/throttle that afr is about right, I certainly wouldn't want it going any leaner than 11.5, I wouldn't worry, often they are made intentionally a bit richer for engine protection, a bit rich for some peoples liking at least it is safe, ie not too lean.
