From your mods he prob left it in 6th gear and rolled on. I have raced my friends R1 and GSXR750 from rolls in their 2nd-6th gears, the R1 stays with me in 6th, bearly, in 5th pulls slowly in 4th kills me, the other two make it look like I threw out the boat anchor.
Anyway, not doubting you fun, just remember a litre bike will kill most cars on the street - especially from a roll.

Bikes are a lot weaker from a highway roll than they are from a dead stop or street start. Take my FZR. It's no bad boy of the motorcycle world, but with a kick *** rider, it could see the 11's. My near stock 87GT can stay neck and neck with it from a highway roll. Bikes get most of their advantage from a dead stop. When you add a second rider, race weight can really jump. An old 750 might weigh 600lbs. Add two riders, now it weighs 900lbs. Probably about 75rwhp, 900lbs = 12:1 weight to hp. Take a mild modded 5.0. Say it's a coupe at 3150lbs with driver. 220rwhp. 14.3:1. A couple points can be pretty substantial, but bikes aren't exactly real aerodynamic in a lot of cases either. If you do the example above with say a early 90's 600 you get 800lbs with two riders, and 60rwhp stock. Now you're looking at a power to weight of 13.3:1. The 1000cc bikes are pretty much untouchable for most cars. Even the weaker ones now put out 100rwhp easy.
