Hi i have a problem with my 2003 r6 yesterday i checked the air/fuel mixture and i have c1-17,c2-17,c3-17,c4-17 i'm i'm pretty sure that are not the factory settings,is there any way to find out the factory settings or to reset them back? the bike was bought from Italy and i don't have how to ask the previous owner!can i reset ecu to the stock settings ? help please thanx !

Thanks a lot ! i do a lot of searching and i found out the settings are different from bike to bike,they are differet from country to country ? there is no way to reset them back to factorry ? thanks again !

edit:if i unhook the battery then i'll be back to factory settings?

no you have to go into the diag settings and change it, since you have a euro model you can skip grounding the wire part.

Yeah i have read that,but i have seen that settings are random from bike to bike there is a lot of combination

well atleast you can have a ballpark figure. is it running ok? the only other thing i could suggest is to somehow get an air/fuel meter to see what its reading under certain throttle positions and just mess around with the settings

I'm thinking since i don't know the stock settings to set them +5 all or 0 the bike is not running so great untill 4k rpm....i think i have to get an air/fuel meter and somehow to read every cylinder and then to set them right but since i have a K^n air filter and a slip on mivv gp even the stock settings are not good,and Yamaha make them respect pollution norms i hope +3 +5 over stock will not damage or affect bike performance but +20 affect that i can tell...
