I installed a afx air fuel guage last week and tried it out on the weekend. At w.o.t it is reading around 12.56 to 12.70. Is that not a little lean for a stock 2006 apex gt? Could bad exhaust dounuts cause it to be a bit lean? Last ride it back fired 1 or twice in a 200 mile ride when i let off the throttle.

Thats about perfect for the combustion in the apex cylinder. 12.9 would be better, but its a miniscule difference
