I will definitively follow your suggestion! After that will be necessary to retouch the volumetric efficiency? I don't think so, just need a confirmation.

 

People say you do but I seldom see much difference. As a side note, if the detonation is bad, who knows how much o2 wound up in the exhaust and messed with to closed loop stuff. I try to never say never.

Your AFFs don't look too bad but we could get them a little closer if you want. I can show you how if you like chasing perfection. It is really easy.

If you can show me how to I am ready to learn! I have MLW HD already because I like to understand but no experience even if I'm a mechanical engineer (not in engines).

 

A little tuner trick... If you are chasing a knock issue and are not sure if you really have knock, toss about 2 gal of race gas in the bike and retest. If the knock goes away in the logs, it really is knock. If the knock does not go away, it is a software issue if you are using Ion Sensing or engine noise (like valve train clatter) if using Pizzo sensors.
