Dizziness under acceleration??

Seriously, when i acclerate my GT wide open in 1st or 2nd gear and hold it to redline, I get a bit dizzy feeling. It is as though my equilibrium is thrown off by the force of the hard acceleration. Has anyone ever had this feeling?

Re: Dizziness under acceleration??

check two things, your helmet fit and swing by the doc's for an inner-ear exam.

If your helmet is putting too much pressure just below the base of the skull on the first vertebrae (known as the "atlas") under added wind pressure or a tilt of the head, that can cause dizziness--it's a really good pressure point for just that, in fact.

If not, you might actually have a mild ear infection.

If that's the case, a combo of antibiotics and pinching your nose and blowing gently, repeating about ten times in a row, doing this 5-10 times an hour for a week or so will help remove the extra fluids that are screwing up your inner-ear (I can't take credit for it, it was in a MCN article by Dr. "Flash Gordon" last year, and I tried it and got tremendous relief from it, so I thought I'd pass it on)

If not, try not wheelie-ing past vertical, it keeps the blood from rushing to your head.

You could be having some vertigo. I had a short bout with this a while ago, it's a major annoyance. Crystals form in the fluid of the inner ear and when they get shaken up they temporarily mess with the balance inputs from your ear, making you dizzy. When I had it tilting my head back (i.e. looking at the ceiling) and shaking it from side to side would trigger the same sensation. This mimics the same G force you get when you accelerate hard... Mine was mild and went away on its own.

You could also be a bit dehydrated or you could need some adrenal support - check with your local Whole Foods or natural grocer for a supplement that would help. I used to get that too, and started taking some stuff and it's gone away.

Re: Dizziness under acceleration??

I knew this would turn into a fun thread....mostly why I began it! Seriously, AND DON'T LAUGH TOO HARD, cause it's obvious I'm NOT an engineer...but does anyone know how many G's one would pull under full acceleration on a bike like a GT??? Probably not many....

I doubt very many. I read somewhere that hard braking is equal to around a 1/2 G. If you really want to know, you could get one of these, but I wouldn't think it would be accurate in corners when mounted on a bike, only for straight line braking and acceleration. http://www.gtechpro.com/

If this persists, I would see a physician.

Thanks! Ordered some a minute ago....

BTW, if my GT accelerates at full throttle for more than 4 hours, do I take it for service right away?!

Very easy to figure out!

We can start by using some road test data, if anybody have the information. Need three piece of information:

1. Start Speed (can be zero, if from a standing start).
2. Terminal speed for the measured distance.
2. The distance ran.

Yep, let's do the math, 0-60 for the K1200GT is something like 3.1 seconds, and 60 mph is 88 fps. So to go from 0 fps to 88 fps in 3.1 seconds requires an acceleration of 28 feet/second^2. 1G is about 32 f/s^2, so that makes 28 f/s^2 equal to about 0.88G.

Of course you won't actually be pulling a constant 0.88G the whole time, so peak acceleration might actually approach 1G.

The K1200GT stopping distance from 60 mph (88 fps) is 117 ft, so the formula we want is v^2 = u^s + 2as, where v is initial velocity, u is final velocity, a is acceleration, and s is distance. This means 0^2 = 88^2 + 2 * a * 117, solving for a we get -33 f/s^2, or a tiny bit more than 1G backwards.

So there ya go, a bit over 1G braking, and approaching 1G accelerating.

Pastor Jack

Thanks for taking the heat on this one !

So far I have learned

1) Someone thinks u r a GIRL

2) About releaving extra fluids in ur ears
3) God speaking through acceleraton ( I kind of knew that one )

4) You could be possible suffering from vertigo

5) The cause of some rib pain

6) You could be dehydrated

7) What Viagra or Cialas is good for....... ( I kind of knew that one )

8) And some math

I found #2 useful suffering through a head cold this week and got some relief from dizziness.

Thanks again for taking the bullet on this one......

You forgot: 9) If your GT is stuck on full throttle for more than 4 hours, take it in for service right away!

Re: Dizziness under acceleration??

If you have low blood pressure, the G's can push the blood out of your brain making you dizzy. Like standing up too fast. Eat more salt and get your blood pressure up or strain you neck muscles like test pilots do to keep from blacking out.

I'm betting that you're just a bunch of old farts who'd get dizzy if you stooped down to tie your shoe lace. I just ride and hang on tight. Of course, LT's are a bit slower.

Just kidding, hope you get it cleared up. Otherwise, I'll be happy to take that GT off your hands.

Re: Dizziness under acceleration??

If you drop Viagra in the fuel tank of your GT, does it up your displacement by increasing the stroke???

(Old racer talking to young guy:
"Put some mothballs in your fuel tank to get extra power"
young guy: "That really works?"
old racer: "Yeah, ever smell mothballs?"
young guy: "Sure"
old racer: "What you do, hold 'em by the wings?" )

Does that mean you can get the same effect as a GT by throwing yourself off a tall building? Hmm, based on the stock market and the upcoming elections, that might not be a bad alternative . . .

No, that'll briefly give you a 0G experience, followed by possibly your last very high negative G experience

...but if you throw your wallet off the tall building instead, it might feel familiar.

Jack,

I knew you were lurking out there someplace. Hey, I've earned the right to ride an old man's bike because I are one. Watch your right hand, too quick and you might eject over the rear wheel.

Have fun and ride safe.

Bruce

FYI- Before I retired from dentistry, most of the fainting or dizzy patients were macho men who had to send their wives and children as test patients before they got up enough courage.

FYI- Before I retired from dentistry, most of the fainting or dizzy patients were macho men who had to send their wives and children as test patients before they got up enough courage.

You got that right! Man, I have the most gentle dentist in the world and I still have to be seriously medicated before I sit down in that chair. This vertigo is so bad now that today I got dizzy on my riding mower!

I thought 0G was basically standing still (ignoring the earth's rotation, and its movement through the galaxy . . . ). But 1G is defined as the rate at which objects accelerate in free-fall (ignoring wind resistance and other forces), so dropping something would by definition give you a 1G acceleration. I agree that the almost instantaneous deceleration would be a problem though. It's not heights or falling that I fear, but the sudden stop.

Some people see the gas tank as half empty. Some see it as half full. All I care is that I know where the next tankful is coming from...

Not quite. When you are standing still, you do experience a 1g pull downward, however your horizontal acceleration component is 0 (because you are not moving). The earth is exerting a force on you to keep you on its surface, and by definition, force = mass x acceleration, and in this case the acceleration is the the 1g that you feel.

So, how can you have acceleration without motion, you say? It all goes back to the definition of force. Gravity is exerting a force on your body in the downward direction equal to your mass times g, but at the same time the ground that you are standing on is exerting an exactly equal and opposite force on your feet, which makes you stay exactly where you stands! Imagine standing on a trap-door. If somebody pull the lever to release the trap-door (eliminating the reactionary force on your feet), then you will get your motion with the acceleration of exactly 1g!

Phew..............
