Calling all Throttle Body Experts
Hey guys, A few weeks ago while doing a compression test on my 2011 S100RR I noticed the throttle body butterfly valves don't open all the way? Didn't think much of it until I was working on one of my other bikes and notice those valve opened a full 90 degrees at WOT (i.e. valve is straight up and down when looking into the throttle body). My S1000RR doesn't feel down on power or displaying any poor running symptoms. It revs quickly and the throttle is very responsive. Does anyone know if the valve should open all the way at WOT? Mine is only opening to about 33% based on what the PV5 shows. I cleared adaptations and reset the throttle via the HP RCK2 software, but I get the same result. I checked the TSP operation and voltage. It climbs steadily from about .5 volts to about 1.8 then stops. No dips or spikes or anything.
