Mr Ass/Geebee do any of you know of available data to see the difference of the suggestions with the existing situation? I saw in the book of Hucho that BMW is doing something similar on the front fender. Should the closing of the front wheel in combination with this fender bring something additional ?
THe real improvement must come with the gearing change. At 50 MPH I only use 1/4 turn of the throttle at 75 MPH this is 3/8 turn. So I am running in an absolute bad region of the BSFC map. Also according to HUcho in some cases an improvement of Cd can lead to a lower FE.
