DRAG RACING!!!

Best so far is a 10.24 @ 138, 1.80 60ft. I have Ivan's jet kit and Akrapovic. Ran a 10.26 before the pipe. I think I can get down into the teen's when I get to run it again. did the 10.24 on a 100+degree day. Running stock ride height, and a 1 tooth smaller front sprocket.

If you wanna learn to be good at drag racing, look at your 60ft, not your ET. In motorcycle drag racing, your 60ft is EVERYTHING. The faster guys will be looking at 1.70's and the lowered geared bikes with great riders will see 1.60's I would say a good street bike rider will see 1.75-1.85 60ft's.

One tip I will share with you though is this. from 1sr to 2nd you will have to use the clutch, or else waste time backing off to keep the wheelie down. The rest of your shifts however, you should NEVER LET OFF THE GAS. Right before you are ready to shift, pull up on the shift lever a bit ( like 4-5lbs or pressure) and when you are ready just "flick" the clutch lever. Do not pull it all the way in, just slide two fingers across it. Thats all it will take to get it to shift.

With the bike running WOT, you can pull up all you want on the shift lever and it will not shift. However the moment you break the load off the tranny it will shift. This will shave a bit of time, also if you are near the finish line, if possible rev it out instead of shifting. This works well for full exaust system bikes. Every time you shift, you spend some time, so shift as little as possible. Good luck guys.:rock

I almost forgot. When i first got the R1 I was leaving the line at 7k, but have figured out that less is more off the line. I now leave the line at 4-5k. I try to get off the clutch as soon as possible.

When you get your 60ft's around 1.9, then worry about the ET. Cause untill you get your 60ft somewhat consistant, trying other things to go faster will be a waste as you will not know if it helped or hurt.

Also I have never been a fan of the foot under the shifter on the starting line. I think it eats too many brain cells while you are trying to stage. You wind up worrying about keeping the bike upright, and not being focused on the task at hand. The R1 is good for about 77mph in first gear, you have plenty of time to get your foot up there

TWISTED

Yes It looks as this may be my new home. I just cannot understand someone being a prick to everyone and thinking he is doing a "service". What was your name in the other place?

I plan on going to Texas a few times this summer, maybe we can meet up. Be nice to meet some of the people who I talk to nearly everyday

Forget it MARTIN, I ain't going up north to see ya.....lol:bash

BROTHER

Cool man, I will keep in touch. I haven't dented my tank yet, but I have broken off the heads of the stock plastic windscreen bolts. Better than breaking the windscreen or the fairing I guess.:boobies

DRAG RACING part 3

Jeff brother you are cool as hell....lol You know usually people on the internet have a tendency to LIE:bs However you are an honest guy. I dig it brother.

I Drag race when ever I get a chance. I do it maybe once or twice a month when the track is open. Sometimes more, sometimes less. I have run my bike maybe 50 times. I really don't know.

You have some killer 60ft times. My best ever on the R1 is a 1.7760ft. I am not a 60ft artist...lol I know that when I leave at 7k and slip the clutch alot I have higher trap speeds. Not by alot but it is noticable. Seems I can get a decent 60ft, or a good mph, but not both.

I wanna say I am in the top of 4th when I cross the line. I have never really thought about it before. I just watch the tach and shift when I get to my pre determined rpm. I was shifting into 5th about 100ft before the line, but realized that it was costing me about .05

I had Ivan's jet kit in my bike before my full exaust and I ran a best of 10.26. The jet kit does not really help on top. I Do not see it shaving off alot of time. A slip-on and the jet kit will help, but like you said not .5 worth.

I will tell you this. I have found this to work for me. When ever I go to the track I always dial in MAX rebound dampening in the forks, and MAX rebound and compression dampening in the shock. I also run my shock on the stiffest setting, street or track. This has shaved about a tenth for me. I hope it will help you as well.

As I said I also am using a one tooth smaller front sprocket. I know this helps. And I use the HIGHEST tire pressure possible in the rear tire without it spinning. Truth be known I can use 35psi cause I come off the line so slow...lol I also make sure the front tire is 40-45 psi. I remove everything from the trunk. I also try to keep the tank empty, to just where the light comes on. I get the light to come on, then add about 2 cups of gas, then the light comes on and I do it again. Just trying to help out the power to weight ratio.

I also run CR9EK plugs. I think they are better. You do not need to worry about indexing the plugs as they have two electrodes. I have removed the air pump and pluming, and trashed every extra hose on the bike. If it dosent help go, stop, or turn I try to get rid of it.

Where are you located? It would be cool to meet at a drag strip somewhere this summer with some other R1 guys. Good luck.
