Aprilia RSV, Tuono AFR tuning for perfection

[@pardonwhat]

Can I ask; why 14.7:1!? is it that most all bikes are that ratio (i.e. petrol engines) or is that specific to V990? Did you see the doner vid?

[@captbarb6642]

The 14.7:1 is meant to be the perfect Air fuel Ratio for petrol engines but rich and lean will occur when riding a bike with no sensor. And I haven't seen the donar video where is it ?

i’m having real trouble posting comments and i don’t know why.. i did send a link in response to your last video , maybe check there for the donor vid link! Failing that hit my icon to the left and if that doesn’t work I’m giving up bc someone upstairs has it in for me:)
