My set up is an av7 with Airsal 70cc kit, 15/15 Dellorto, Ninja g3, and mild case matching. I am currently GPSed at 43mph. I have a Dellorto PHBG 19mm and a stock head that was milled down 2mm. This is what I am wondering what kind of speed increase am I looking at if I install the high comp head and carb?
<p> note: the bike wont run with an air filter. Without the filter bike runs and idles perfect.
