20 mpg less than advertised?

I accelerate hard with my 9 and get 52 to 56 average, I would think riding a Blast conservatively would net more than that...

Your Blast will do 96mph with stock ignition at 6500rpm. The stock valvetrain will support 6900rpm before valves float.

My Blast is very modified, I was getting 30-35mpg. Then I went to EFI (system from an XB9) and have pushed that back up to ~50mpg.

if you're stock, you might get 60-ish. The more modifications you do, the lower your mileage drops.
