Gearing for Daytona-07 GSXR 600-stock motor

[GSXR RACER MIKE]

I should have mentioned that I'm heavy too, I'm 230 lbs. When I was racing my '99 GSXR 600 (carb kit, air filter, full race exhaust) and used stock gearing, I couldn't even get close to redline at Daytona in 6th gear because of my power to weight ratio - there just wasn't enough power to pull the combined weight. I believe back then I was using +2 on the rear just to get close to redline at the fastest point in 6th.

I realize your power to weight ratio is going to be better than mine was back then, but your still going to be lower than the majority of the 600 field. I'm guessing your bike & racer weight compared to your bikes Hp is probably going to be around 5.6 - 5.7 lbs per Hp range, your going to be up against racers in the supersport 600 classes that are around 4.6 lbs per Hp or lower - that's a huge difference! Get into the 600 superbike and GP classes and your going to be up against some racers that are down around 4.3 lbs per Hp (or even lower) - those guys are just flat out going to run away from you on the big track. I've tried to explain this to lighter people who have never been heavier than their competition and they seem to have so much trouble grasping how power to weight ratio makes any significant difference, I definitely understand because it's always been a factor for me.
