I got my full system taken off (an F4i which has FI) and the stock headers/cannister put back, but i'm still getting the crap ass mileage that I got when i had the full system on. When i bought the bike stock, I got about about 200km before i got reserve light. When I put on the full system and now, it goes on at about 160km. Shitty eh? Anyone know what's gonig on? And i refuse to believe i'm riding any harder or longer.....40km difference is huge.
Is it possible that something is wrong with the ECU and it didn't go back to "normal"?
Anyway, comments please!
