I recently purchased a 2010 Cbr 1000RR and after putting 636 miles I changed the oil to synthetic and went to get a baseline dyno run. I live in Florida and when I did a 4th gear roll-on the bike produced 141.89 whp but after a couple of runs I measured the exhaust gases using the ega on the dyno. When I did 3 more runs I noticed that it was running super rich from right around 9000 rpm to redline, the air/fuel ratio dropped to almost 12.0 to 1 a/f ratio.
