[QUOTE="jammess, post: 1318153, member: 89387"] In reading through a few older threads it seems some FJR's are troubled by lean AFR surging at constant throttle (cruise) when the ECU is or should be in closed loop. Are all model years effected by lean surging or did Yamaha come up with a factory fix? I'm most interested in the problem if it applies to the 2010 model. If my new to me 2010 has this problem I know what I'm going to do to fix it but hope I won't have to. Thanks, Jim [/QUOTE]
