For R1150 series owners only:

On the bottom "spline" of the throttle body casting is a Bing part number that should start 75/45/???. The third number group should be in the low 100-110's. If you're really bored in the next while (days or so), please let me know...

MODEL YEAR
TYPE {GS, RS, RT, R }
Left Side Number Sequence (Pretty sure these are odd numbers)
Right Side Number Sequence (Pretty sure these are even numbers)

I've got a truly whacked-out idea or three, but I'm lacking field data to make a judgement call. Don't ask really why, its one of those "if you could" sort of things...

Thanks!
