Guest goldgooz Posted May 4, 2003 Share Posted May 4, 2003 Hi Everyone, I need some help. Recently had first service done on my o2 LeMans(1000miles) and now she feels slightly lean on bottem and mid range--light surging around 3000 rpm and a occassion spit at idle. Dealer set CO at 3.4 Is this a little low for best performance? The bike ran perfect before service. Thanks in advance. John B. Link to comment Share on other sites More sharing options...
Guest russ Posted May 4, 2003 Share Posted May 4, 2003 Mine was originally set in the 5-6 range but mpg was about 30-32. Had it leaned to 3.5 or thereabout and mileage is now 35-40 mpg. I do not feel any lean conditions so maybe it is a tps issue? Very tricky these ecu's. I am just a caveman, I do not understand these modern inventions Link to comment Share on other sites More sharing options...
docc Posted May 4, 2003 Share Posted May 4, 2003 Cavemen and spacemen have this in common: Carburettors or FI , tuning fuel delivery is like conducting an orchestra. Let the brass get too loud and the strings change their tune. All must be in harmony. I can't imagine the frustration of riding the V11 without the benefits of a digital multimeter, mercury columns and a book or two. ( see "Guzziology" by Dave Richardson) A little tweak on the TPS, some VERY careful synchronization and this motor is a ripping panther! Link to comment Share on other sites More sharing options...
