The 27zr with 496ho/425hp went on a fun/lunch run this past sunday with 7 total go-fasts here in Md.We left the NE river around 10 am.Cool temps but not freezing.I had 3/4 tank and 3 crew members with me.The best top speed that Ive been able to go was 69.7 this summer with an empty tank and no riders.Well I got 69.8 and then hit 69.9 gps.Iam going to run the tank down and go out by myself,........Hope to get 70!
