Dear F4-isti,

as you may know, a lot of fuel injected bikes have lean mapping especially if exhaust systems are altered. It's most noticeable on twins, to get them through emission testing (I think). Do you know if anyone has had a look at the injection / mixture profile of the F4/S to see if it could be improved?
