What RPM are you shifting? MPH seems low...otherwise congrats on the times!
Shifting at an "indicated" 11500. That pass with the 121 mph in the 1/8th is my fastest I believe in the 1/8th. I have seen the bike go 150.xx in the 1/4 before, thinking my gearing took down the 1/4mph a hair maybe. Maybe I was a couple pounds lighter then!
