ok, I know, pictures or it don't exist, so lets say it don't exist, so what is your thoughts on why a mav -2 seater would do 75mph top speed now for 38 hrs, then all of sudden for no reason or change, start doing 78 by gps confirmed. friends did this. he has done a lot of speed testing using gps in the same area, had the 12 hr service done, so that is not the reason, 38 hrs now. 100 % bone stock, always test it between 4 and 5 bars. I don't have a clue on that, any thoughts?
