Default 45mph at ~7600rpms

Went riding with a friend today, he was on a suzuki dualsport 600something.
Was finally able to verify my top speed on flat ground was 45mph, and the tiny tac read right about 7600rpms. Even hit 8500rpms downhill....I was HAULING!
Im running a 36t rear sprocket with 26", 1.75" tires.
Have ALOT of port work done (transfer ports fully opened, boost ports, piston ramping, piston skirt trimming, port matching), as well as puch hi hi head, race carb thats ported further, modified minibike exhaust (hopefully making a new one out of a mx expansion chamber to further my powerband up the rpm range).
Very happy with these speeds, cant wait till i can hit 50 and get it gps verified!
Oh, and i switched to amsoil saber professional, currently at about 60:1. It seems to be running VERY smooth, time will tell though!
