What should the idle RPM be on a Yamaha FJ 1200?
At this point the bike must keep a good idle and be quick responsive to the throttle. There must be no problems too riding at low speed, at around 2.500 – 3.000 rpm. To perform the following tests I look for a quite and clear straight road, lightly uphill if it is possible to further expose any problem.

Why does my Yamaha FJ 1100 run well when hot?
If there is any problem this is due to the needle height. If the problem is worst when hot then the mixture is too rich. If the bike runs well when hot but there is problems between 4.000 – 7.000 rpm, the mixture is lean.
