Hi, I have a 2016 RC390 with the following mods made last year. Current ODO = 2,250mi
Yoshimura CF RS-9 exhaust / K&N Air Filter / MMNTBX Air box mod. / PC V with map from Chad (Commonweatlh) who also flashed ECU with "Akra"
MPG is down this year to about 55 I don't feel any real power loss. I use premium fuel 93. I had the service done and the valves checked. There is a little soot in baffle, it just took 1/3 quart oil and there is an alcohol/fuel type smell from exhaust.
Any ideas?
