I can't seem to pin point the performance problem on one of our local BMW club members R1200S bike. The bike just started running real slugish on a ride.

This is what has been done so far. Sea Foam has been run thru a few tanks of fuel before he brought it to me. All four spark plugs looked good (not lean or rich), Compression & leak down are good, Valve lash is at spec., Fuel pressure is 50psi & the return line has good flow, I flowed the injectors & at 43.5 psi & they both flowed 25cc on a 5 second static test, The injectors also had a good spray pattern.

I think I'm down to a sensor problem any ideas ?.

Thanks, Dave
