Arch, if you are searching for a means of improving your lap times on the fat chick, work on corner exits. That is where you'll reduce your lap times by the largest margin. It's also the place where you will learn to pass riders with ease. The biggest advantage you have (The only advantage actually) is horsepower. Use it to your advantage. This is accomplished through line choice. Most preppy track day enthusiast refer to this as "Late Apex", us hillbillies simply call it "Point & Shoot". Carry your line deeper into the corner before tossing that heifer on her lips quickly and get her back up on her feet with the throttle against the stop and you'll come off the corner like a gut shot cat. The additional speed you get from early throttle means you carry that speed all the way to the next corner. By squaring off the corner and getting your bike pointed up the inside you'll be able to pass those smaller bikes who depend on corner speed. You will be hard on the throttle while they are still leaned over and unable to accelerate.
Next track day, snare yourself a track coach and ask him/her to show you how to square off your corner (Late apex/Point & shoot). If they have no idea what you are asking of them, find a different coach.
If you are serious about the track, invest in good tires. Dunlop Q2 or Q3's are an excellent choice (My favorite for street & track). Have fun my friend!
