Disclaimer: I am really new to bikes! so if this is a really dumb question...well thats prolly why
so i was doing a burnout in my backyard, ATGATT WAS in effect mind you, and it was going ok and then my bike caught and...well...i launched, popped a wheelie and i pulled the clutch in and my bike kept going. needless to say i ran into something and flipped over my bars and dropped the bike. my question is this:
why did the clutch not disengage and bring the bike down? was it just that i had too much momentum and it just kept going? i couldnt find the rear brake in time to try to bring the bike down.

Momentum.
You need to close the throttle and the engine braking will slow the bike down.

Surprised thats the only thing you broke!

+1 with Blade, the same as if you were to pop it up onto a paddock stand and dis engage and re engage the clutch the rear wheel would spin until the drag of the bearings/brakes etc would stop it.

noted! good to know. i did crack the upper fairing i think and maybe bent the left foot peg....didnt get to see it too well before it got dark. I was putting it away and i got an itch to practice doing a burn out for when i drag it next year. do you want higher rpm like for a car while doing a burnout or is the ideal rpm "just enough to get the job done"?

I don't do burnouts (even when I have done drags) but I would think keeping the revs up would reduce the chances of the tyre hooking up.

thats what i thought but i had it at about 7000 and then it just hooked outta nowhere and sent the fron tire up and not a half a second later i pulled in the clutch and the front came down riiiiight before i hit my hand rail on my porch...it was about a 30 foot distance i think

7000RPM would be pretty low I would think. A hard launch is probably around the same point. I launch the 929 around that point.

hmmm....youre prolly right. i think im just used to v8 motors where its a cardnial sin to go over 6500 rpm. so what should it have been at? maybe 10000 rpm? and what would happen if it sticks there too? haha maybe im over thinking this?

Personally I'd stop messing around with burnouts and put the effort into learning to launch the bike.

to be honest this is my 3rd attempt at a burnout. and this is exactly why i tried too. id rather have this happen before i get to the track you know? i have nowhere to work on the launches until next spring as i wont do that kind of stuff on the streets.

Why are you wanting to do burnouts though? All you're doing is burning up your tyre, clutch and oil and annoying your neighbours.
I don't know when spring is but surely there's somewhere you can practise launching?

or do what the machine was designed for (turn):smilebig:
thats coming too bro, next spring. I'm already paid for a 2 day track class! btw you think bikes were only designed for twisties? cmon man it only makes sense to drag bikes too. power to weight ratio it far too great not to send em down the quarter!

The only reason to do a burn out (as far as functionality) is to warm up the tire. and like i said i was just trying to figure out how to do it before i get up to the water box and look like a retard! :smilebig:

are burnouts unnecessary before you send it down the quarter? i know they are in drag cars. Im all new to this 2 wheels thing. any help would be great!!

Yep, sportsbikes are built for cornering. If you want to drag race get a ZX14 or Busa :)
Doing quarter miles are interesting the first few times, then it's boring as hell standing around for hours waiting for your thirty second rides.
You don't need to warm the tyre to launch a bike, at least not until you can make good solid launches. If it's spinning up let some air out and run a tyre warmer if you can in the pits.
Cars need to do burnouts because they're heavy, underpowered and boring - what else can you do with them :)

Depends on the weight, power and tyre footprint - and how well you can get the clutch out.

I am working on a "busa fund" this is my first bike (my cbr 600 f2) and im am still very much in the learning stages! good to know about the burnouts wish i knew about 3 hrs ago!!:smilebig: I am still trying to grasp the differentiations (is that a word?) between cars and bikes so please bear with me!
