finally got to take my nitrous injected cbr-929 out to the track last night with all my new found power. i am still running the stock wheelbase (55 inches) with the stock gearing and no launch aids (wheelie bar, dog bones, lowering straps, etc,) whatsoever. :screwy: the air temp last nyte was in the 80's. i was doin some monster wheelies out of the hole in 1st gear and when i shifted into 2nd i would set the front tire back on the ground and hit the nitrous when the bike would just wheelie so hard i would have to let of the nitrous to avoid flipping the bike. it was all i could do to shift the bike into 3rd gear to avoid hitting the rev limiter. once in 3rd gear i would hit the nitrous again and the bike would race thru the gear so quick i would bounce off the rev limiter before i shifted in to 4th gear. i was going thru the finish line at the top of 4th gear at speedo indicated 148 mph! hell yea!!!
i weighed my bike on the track scale last night and it came in at 425 pounds wet with 1.5 gallons of race fuel in the tank and open header (no mufller on the bike). i weigh 225 pound with gear on. i dyno'd 169 rwhp last month on a chassis dyno in phoenix spraying a 40 hp dry shot of nitrous. my best 60 foot time was 1.90 seconds. i am gonna re-gear the bike up +1 in the front and -3 in the rear. i would expect my et to drop another .23 seconds. this will also help me to reach a top speed of 190 indicated mph out on the freeway in 6th gear. i maxed the bike out last month on the freeway in 6th gear with the stock gearing and hit a indicated 175 mph. so with the new gearing i am gonna use the nitrous in 6th gear and go for 190 mph. :angel: the pic below was taken at my local dragstrip here in tucson, arizona. our track has a elevation of 3,100 feet above sea level. this pic was taken back when my bike was stock before i started modding it with drugs, etc. [image]http://www.viperalley.com/gallery/data/500/2162resized_3.jpg[/image]
