steve m Posted April 22, 2009 Share Posted April 22, 2009 K&N filter + Quill exhaust = Dyno time !! Going to be the only way to sort the fueling out properly.. Link to comment Share on other sites More sharing options...
pilninggas Posted April 22, 2009 Share Posted April 22, 2009 CO2 sensor? do you mean o2/oxygen sensor? This tends to control steady state throttle fuelling under light load and therefore is not an issue at idle (efi bikes tend not to use the O2 sensor at idle or full throttle) so as ^, it needs a tweak on the dyno, maybe powercommander.

barwell1992 Posted April 22, 2009 Author Share Posted April 22, 2009 ok thanks for the replys and by the CO2 cencer i mean O2 cencer its aparently helps the bike not be so rattely it fine on strat up and all that but just not when riding it :/ EDIT: well i told my dad and he would like to know where the closest one to warwickshire is and how much will it cost or is it worth buying a powercomander ??? also if i droped the airfilter out and put the old one back on would it solve the problem because on the quill web site it says no modifications needed :S Link to comment Share on other sites More sharing options...

That is ,, unless you are going racing ?? Link to comment Share on other sites More sharing options...
