Bike time runs

I just got home from K.C. test n tune today. It was only 48 degrees and very cloudy, with a 10 - 12 mph cross/headwind. I saw a few Pro cars with the front wheels up, but with the extended street tired street bikes, traction was hard to find. Last year at this track I had 1.52 60fts and ran a string of 10.teens @ a buck thirty and change.

On my first run today, I tried to take up right where I left off last year. Leave at 5200rpm, get the clutch all the way out and twist the throttle wide open at the same time within the first 40 feet. It didnt work today Spun hard through first gear even while rolling out and then back in on throttle.
RT .049 60ft 1.87 10.62@129.06

2nd run I left at 4000rpm and rode the clutch to just past the 60ft mark. didnt spin.
RT .059 60ft 1.76 10.52@129.06

3rd run I left at 4800rpm, but still hung onto the clutch to the 60ft cones
RT .010 60ft 1.66 10.32@130.09

After that I loaded up and came home. I was cold and homesick. (wimp)

Launching a streetbike is very tricky. There are so many variables. RPM, clutch release speed, how quickly to roll in the throttle, seating position, forward lean angle, what you do with your feet, and if you do any one of these wrong, you could bog the motor, burn the clutch out, spin, wheelie, drive out of the groove and spin farther down track.

With that being said, let me ask a question. How come people say "DRIVE a drag car" and "RIDE a drag bike"? It seems to me that the bike guys are the ones doing all the DRIVING ;D

Next saturday will be Johnboy's turn to see what he can do with this bike at Gateway. I'll be re-learning how to ride Marks busa

Do you think the muffler changed the performance?

At least you go to do some testing. I sat home and watched it rain at NASCAR, NHRA, IRL

[deadmoneydenny]

Its hard to say if the muffler hurt or helped the performance. It ran 130.09 today with a mild launch and a headwind. 131.56 is the fastest it ever wnet last year. A streetbike can easily variey a tenth and 1 or 2 mph just because you wasnt holding your head right or you left your feet down too long, or just because!

Glad to see you made it out already this season. Your ride is in the trailer ready to go. I want to see your first pass on it this year. With it still having the SAME GAS it had all winter and with just starting it to move it around it will probably look like a diesel truck with soot and cobwebs coming out of the muffler.

My first pass on it will probably be about as slow as a diesel truck too. You know my first pass each weekend was soft, just imagine now after not being on it since last summer.
