Default Conversion RWHP to Crank HP ?

Hi,
I'm Chris from Germany and a I have a question to the Dyno Specialists here.
Yesterday I put my modified 883/1200 on a Dyno. The resulst are :
73HP at 6200RPM and 81lbs/ft at 3000RPM (very nice to ride ;-) ).
These are the values at the rearwheel. There was a little computer problem and it was not possible to make the correction. Does anybody knows, how many hp this could be at the crank ?
Thanks and greetings from Germany
Chris
