I took the bike out to the dragstrip for the first time this last Friday. I'm pretty green when it comes to racing a motorcycle, so my times pretty much sucked.
The first run my 60 foot time was 2.4 seconds. I almost killed the engine, then disengaged the clutch, open throttled and reengaged the clutch to save from killing the engine. Ran 12.8
Second run out I opened the throttle to about 5k RPMS and dropped the clutch. Since the track was gripping so well, I ended up pulling a wheelie, letting off the throttle then reacceleratting to run a 12.7 @ 113... My 60 foot time was nearly 2.6 seconds.... I went back and compared my times to my 89 foxbody.
My 60 foot time was nearly 1/2 second BETTER in my mustang. I really need to work on my hole shot, problem is the way I race my mustang obviously doesn't work when racing the bike. Advice on how to hole shot??? Dropping the clutch doesn't work since all I do is wheelie.

I need to find exactly where the power band ends on the dyno and maybe change my shift points, (I was shifting about 300 rpm before redline.) and I should be able to easily cut off5-6/10ths ofa second by having a better launch..
low 12's should be easily acheiveable with a better launch, but was wondering what other riders where getting out there in the real world on a stock bike....no exhaust, power commander, etc....Also I stopped after a few runs to watch other bikers launch, but since they had wheelie bars coming from the back, dropping the clutch wasn't a problem for them.
I did a search and found this link. Is 11.28 an accurate time for a completely stock06 F4I with an experienced rider?
If this is accurate how/why is it that the 01 F4I and even the 2000 F4 has a quicker time than an 05/06 F4I??? I know obviously atmospheric pressure, temperature, the racer, gear ratios, etc, etc, etc all plays a role in the final time, butyou would think that the magazine publishing these times would factor in differences in temperature, atmospheric pressures, etc before publishing these results????

No they have pro riders do those time man. evryone sucks there first time at the track dont swet it.

 

and the second time and the third....

 

me and a friend ride down to the local track about every friday and ive been itching to do some runs just to see what it feels like. ive heard 11s also with pro riders but they are pro riders so they have a lil more knowledge and skill than you and i. just keep at it and youll get the hang of it. keep us posted on how it goes.

 

I read an article in a mag from about 4 years ago where a pro rider took a stock 600 and actually made into the 9's on the 1/4 mile. But that took him 4-5 passes to get used to the bike (and also they lowered the front buy using straps). So if a pro rider in perfect condtions usually get 10's and only better after several passes, then no matter how good we think we are as street riders, we are never going to get near those times or speeds. But practice makes perfect.

 

Your 60ft time should be at least a 2.10 (that would turn Your times to about 12.00 at 116mph.You need more riding time to be comfortable with the clutch. Strong riders can turn 1.90 or better 60ft and that would put You in the 11's. To run low 11's on that bike You would need to weigh less then 150lbs.

 

That still doesn't explain why the 99 F4 got better times than a 2000F4I. It also doesn't explain why an 01 runs 1/2 a second faster than an 06.

 

I think You are reading too much into that web site.First off, those test were done at different times, on different tracks, with different riders.On motorcycle.com 2005 600 shootout they record the 2005 CBR600RR as doing a 10.86 at 126mph.Motorcycle USA recorded the 05 CBR at 10.99 at 125mph.At the same time I have Sept 91 Cycle article were a 135lb pro drag racer Jay Gleason pulled a 11.02 at 125 on a 91 F2!

 

sorry to tell you but your 1/4 miletime is gonna be the same time no matter when you leave the light at the track. you can sit at the green light for 20 seconds and you will still have the same ending time.
