My new gearing was perfict @ Nelson Ledges Sat.(15/50) I was able to wind out 5th on the back straight befor rolling off and on again for the kink,and had my rpm up into my power range with thr gsxr cams exiting the 4th gear turns. But I couldn't get the tires to hook up. The track was cool with a light mist/rain. The 1st practice I gradully picked up speed waiting for the tires to get to temp,and it felt a little greessy but started to stick on the 4th lap. 2nd practice I waited for a few laps to get up to speed and a light rain started,did'nt look too bad but I felt the back slide abit in 1 and 4 so I thought I'd slow up abit befor hitting my turn in points. I must not of slowed up enough,I came by a couple of bikes,rolled off and started rolling back on through turn 4/5 and it started coming around. I didn't chop the trottle,kept weight on the pegs and thought I'd saved it when like slipping on the ice next thing ya know I'm sliding down the pavement @ about 80-90mph. Untill I and the bike hit the grass,then it turns to tumble.The leathers and pads did their job protecting me,but still moving very slow and taking short breaths. Feels like I strained muscles down the left side of my back and bruised some ribs down the left side of my back. The bike needs a set of bars,footpeg broke,dent in tank,broken pastic.The NRC case cover did its job,and the left one should be replaced. Nothing is as bad as my ears though, the wife is not a happy camper. I think a couple home improvments will be done befor the bike is fixed.
