Me vs. my bros Yamaha 750

[vtec8ter]

that is my general rule. i can run high 9's on spray. and there is no way i get near enough mph to hang with a bike. the bikes that come to my track, that aren't trailered, average around 10 seconds at the worst. the best i have seen was a 9.37 at 153 by a 01 hybusa. so i leave them alone. but if it's your bro... keeping adding mods and getting better at driving, and make it close.
