[QUOTE="aavmann, post: 402270, member: 7538"] Hey all, I'm not about to pretend that I know that much about the technical details to the workings of the FJR's engine.. :rolleyes: Just did a spark plug change on my 03 (37000K) and cylinders 1 and 3 were blacker than the rest ( running rich I'm told )... is it feasable to do a CO adjustment to just these cylinders ??(i.e. bump up the values) or is this goverened strictly by a TB sync (air screws / butterfly adjustments) those who know (and this board has a lot of very knowledable people thats for sure ) should be able to understand. Yes I have done the Barbarian mod... although I remeber leaving the values as they once were because the bike seemed to lose power and shudder more. But seeing these blacker plugs has got me thinking and I cant find the answer in any searches that I have done... thanx in advance... [/QUOTE]
