And why the hell did this turn into an argument over if the sticky tire made a loss of HP?

I saw a bike on the dyno before the tire change, and later on the same bike on the same dyno with a new pilot power, lose power.

Again, I could give a rats ass about how much power my bike makes in the end.
I said a few times that Im happy with it, and have no interest in racing it top end or whatever.....so why all the flames?

I was wondering if the #'s themselves seemed a little low to anyone else. Whatever....back to lurking

they are only trying to help you get your post count up......right guys?

Ok, a worn piece of shit tire is going to grip as well as a sticky pilot power.

I realize my example was exaggerated but you're plain retarded if you cant see how the grip of a tire affects HP ON A DYNO.

Im making no correlation what so ever with real world power. You will NOT notice anything or lose any power on the street.

Its a proven FACT that if you lube a chain like crazy, you will gain 1-2 hp on the dyno.

The tire's diameter also has something to do with the power reading, there are many factors that deal with how a dyno reads power, and if you dont think rolling resistance has anything to do with the number then you're crazy. Laugh all you want.

O.K I'll humour you a little more. On a dyno there is no additional resistance caused by friction because gravity is remaining constant at 1G. So the only thing that would alter the friction would be contact patch. Yes lubing a chain will improve gains because it reduces friction, and yes increasing the diametre of your tyre (therefore increasing the contact patch and therefore friction level) will reduce gains. But to say your new tyre is sooo sticky that is reduces power is just stupid, embarassing and sounds like a school yard debate. BTW how old are you??


That other guy had the right idea, maybe your new tyre has too much air in it, pretty heavy stuff that air, could be loosing tons of power bwhahahahahaha

Please keep it up, me and the guys are getting sore stomachs from laughing!!:bow

Now can all you people see what my rant was about the other day!!!

Zoli Im not trying to flame you, it takes two to argue mate.

You are saying one thing and Im simply trying to help you from looking like a dickhead by repeating the same kind of idiotic statements in public without having the safety of the internet to hide behind:beer

You spend a lot of time watching bikes on dynos huh?
Seriously, just ride the stupid thing..

I will admit that it does sound silly, and I will retreat and shut my mouth until I pesonally see this happen.

My tuner said this to me, and to the other guy that was dynoing the bike who had the same tire.

I was quite sure I was making sense, but not so much anymore.

Im 22. And I will go just ride the damn thing. heh.

its all good, so to everyone :riding :riding :riding :riding and a big :thumbup

I dont wanna start my posting reputation if you will by making myself sound like an idiot.

I normally dont argue anything Im not 100% sure about, and this being something that Im not sure about, I can admit I may be wrong and will back out. :beer

 

[RavenR1]

So what you guys are saying is i should go to the junk yard and get a tyre that has just a liitle thread showing, so as not to be to sticky. Then in the process of oiling my chain i should also oil my tyre. Then I make sure to only have about 10 psi of "heavy air" in it plus put two stickers on the faring and I should see about 10-15 hp increase. Let me know if I have got this right as i think my local dyno is open for a couple of hours tomorrow.

OMFG mate you just went to the top of my list of people I respect!!! You dont know how bloody rare it has become to find someone these days who ISN'T prepared to argue about something they dont know about. If you were over here in Oz I would buy you a beer, good on ya mate:thumbup :beer

the weight diff of the new tire vs the old tire should be the only thing effecting it, not the grip.

at least thats how i see it :dunno

 

[Farmer-Ted]

I think I can see what he was trying to say. It's called rolling resistence. The tread on a super soft, sticky tire will deform slightly more than one with a harder compound. The one with the soft compound will require more 'power' to roll it. It has nothing to do with the tire actually sticking to the roller. An exagerated example would be trying to push a car with flat tires as compard to pushing one with overinflated tires. Would this really make a noticable difference on a dyno? Who knows. It would probably be very small or unmeasurable, but present.

 

[RavenR1]

I get it now, it would be like pushing flat tires, that have been rolled in carmel across a counter top that is actually slanted up hill, then we take the physics into the equation if we have 3 mice running in a wheel at the same speed if the force of the moving air could create enough back pressure to move the fan. I know i can kick there ass in a race now!!!


:rock :finger :rock :finger :rock :finger

:lol :lol

And make sure to remove the heavy air too


I heard you can get light weight air on ebay. :crash

Hey flatknacker, I would have said this nicely if you had been respectful, but your reply reeks of arrogant, ignorant douchebag.

No additional resistance because of friction? Say you have a tire with just enough grip to prevent any slipping on the drum. Any tire with more grip than this magic tire WILL show a loss of power, all other variables being equal. Oh, and yup I'm pretty sure you are right about gravity staying at 1G. But if I'm not mistaken when you use racheting straps to pull the bike against the drum, it just may change the amount of force exerted on that tire. It will also exaggerate the frictional losses caused by the stickier rubber. You may want to get your money back from Cracker Jack for that physics degree of yours.

And just in case your curious, I'm 23...

I swear I hardly come to this site anymore because of this crap. It used to be a good place with experienced riders sharing their wisdom and the others taking it all in. Now there only seems to be try hards and wanna bes.

Oh the irony! All this mouth running by someone who doesn't know what they're talking about. Who also bitches and moans about people throwing their .02c in about things they don't understand! wwn3d "Flatknacker", Australian for douchebag.

Thanks for more eloquently stating my point with the sticky rubber thing.

NP, I just hate to see someone who actually grasps the concept, and did his best to explain, get flamed into a corner.
