Drag Strip Advice - August 5, 2014, 02:29 PM

So I went to the NHRA nationals at Bandimere a couple weeks ago and saw they have a "Test and Tune" night every Wednesday. I figure I should probably run a bike down a drag strip at least once in my life so I think I'm going to go try that out tomorrow. If nothing else, it's pretty cool that you can run a national drag strip under the lights for $30. Any advice for someone that knows approximately nothing about drag racing?

Go have fun, it really is that simple if you are only doing a test and tune.

Launching a bike without getting all wheely-ey and squirrely is challenging

You hold the throttle wide open for about 10.5 seconds. Then you slow down.

most likely they will not be treating the track on a wednesday test night. spin the tire just a little, no smoke needed just to clean the tire up a bit and a little bit of temp otherwise in my experience it will spin off the line. but all tracks are a little different.

first time i did it the lights and people watching got my nerves a little on the first run and then i relaxed, my third run was my fastest. i got 6 runs in my first time at the track, the last 3 i was trying out higher rpm launches and my times suffered. my fast run i just did what i would normally do if i was taking off hard from a stop light on the street.

Take your toolkit out. BTW - This is a joke, toolkits back in the day weighed a couple of pounds. Nowadays I think the toolkit is just a 6mm allen wrench.

Things you could do depending how far you wanted to take it...

1. Remove any excess weight that you have stored on the bike.
2. Enough gas in the tank to just get you down the strip and back. Add more between runs.
3. Drop the PSI of the rear tire about 5 PSI, maybe 10 PSI? maybe more? Guys who have done this should advise...
4. Reduce preload on the front fork, raise fork tubes in triple clamp to lower front end.
5. Put rear shock on stiffest settings.
6. Swap in a smaller battery, disconnect any lights that you can.
7. Remove your sidestand, turn signals, lic plate brkt.
8. Take the biggest shit you can muster before your run(s).

Just have fun. There will be guys there who really have their bikes dialed in. I took a stock 1982 GS1100 streetbike to Capitol Raceway in 1983. Had a lot of fun but never really got the whole "dial in" aspect of drag racing. I made 4 or 5 runs before I was eliminated. Best was an 11.99 1/4 mile. The ticket is still around here somewhere. Back in the day the fastest magazine guys were in the 10's on that bike. I was dissapointed I couldn't go faster. But it takes a lot to knock of that last second.

Amazing thing was. I met a guy there riding the same bike. We have remained great friends since.

Good list Morse.

If you are going to swap batteries, you would be better served to just strap the front end.

That's overkill for the first time at the dragstrip.

Pull in the mirrors and go. On my VFR removing the mirrors was good for several mph on top.

Agreed. My comment was ... "however far you want to take it"...

I missed the mirror removal. Good call.

I was lazy and just showed up, no prep, but it was a lot of fun. Definitely a good way to spend an afternoon and thirty bucks. Reactions times got better, but ET's were relatively consistent. It just wants to wheelie so much.

Best was 11.139 @ 130mph which I figure isn't half bad considering the mags got 10.93 out of it at sea level and bandimere is at 5,800'

For the air quality up there that is a phenomenal time. Well done.
