Wasn't braking much harder than I had for the previous 20 odd runs of the day. Brakes did feel extremely faded though, track marshal said it may have been the front slowly losing grip over time.
You can hear it lock at some stage during the video.
Now all you experts can tell me what I did wrong

42PSI. Had done a run no more than 5 mins prior which lead me to believe that the brake fluid may have boiled (expert advice needed). Tyre should have been warmish, its not worn either

42PSI is what is stated in the busa manual. Recommended on quite a few busa websites for LSR racing. Should it be lower? Never had any problems with it before.
Front wasn't strapped. Bike at stock ride height

Just for you I can eat a few more cheese burgers tonight ;)
If the manual says 42 then run 42 I guess but I would lower it if you are doing any sort of track or drag event, means your tyres will heat up faster to start with, Can't say this was the cause of your accident though I am just an opinionated KB'er

I run 38F and 42R for general daily riding and a lower them a smidge if im going for a short spirited ride,
I would run them a bit lower if I didnt use my bike for commuting but I found if they are a fraction lower I seem to chew the centres of the rear tyre out too fast,
Thats running on Pilot powers on the Twin

Why didnt the motor shut down when it went down? I thought all injected bikes had a tip over switch?
I see a bottom end job in this bikes future.

Mines long wheel base and front heavy compared to most bikes. Its also claimed 270kg.
Over the last few years the tyre pressure recommendations seem to have risen. I used to run 30 front 32 rear.
I wonder if a brake piston has stuck on the busa. Would like to see the pads removed and some photos of them.
I had a stuck piston on my race bike that caused a disc to lean over and drag when hot. Destroyed the discs and low sided me in the Ss at Manfeild.

Hayd3n is the king of plastic repairs,
If you cant find new fairings or you decide to repair those and you jack something up with Hayd3n (if you decide too and he can help you I guess) Let me know and I can sort you out a sharp price to freight it down and back.

Under real braking the Busa will push the front, the line of force runs in front of the bike, not down-lockup is easily achieved if you don't set the front up correctly, on a tyre pressure that high, a fraction too much lever in one quick grab and you will lose it.
Be interesting to know what your spring rates,sags and compression up front are, add to that tyre pressure and rate of lever grab, somewhere in there is your answer.

Always got the apex at turn two wrong everytime at champion..
never liked the left lane at meremere on the bike or in the dragcar.
10.9 is respectable and a good top end terminal speed trap as well
its the reaction and 30 and 60' times that tell a lot.
prop's that you walked away like you did and the bike minor damage
( the walls are deadly ) at night during the nightwars on the bike its
freaky..
the runout area at meremere after the 1/4 is 400meters
given your terminal speed your going to use at least 350meters of that
trying to pull up! :buggerd:

It must be in the first few meters. The 14s showing 145mph on the gps but running high 9s and low 10s. Not a lot of top end speed difference but a second on the track.

Had a quick look, like choppa said cold tyre ? (and high pressure ?)
Shit yourself and yanked the front brake ????
Can see you launch slowly which shows doing 11 sec on a Busa.

Been riding 7 years. Last accident was about 3 years ago when I was being a hooligan on my 250.
Brakes felt like they were fading so I did give it a bit more lever than I should of. Should have let them cool off properly before doing another run. Ah well its done now, time to fix up the plastics and get her back out there.
There is visible blueing on the right hand disk and it did look a bit warped. I will take a good look at it when I get home.
A little bit stiff this morning but I still managed to run the 3km's to work. I will get up some pics of the damage to the leathers tonight and a couple more of the bike

Wouldn't have thought brakes would over heat drag racing? Unless the blueing is a pad down to the metal ??
Being a little stiff in the morning is a distant memory I'm afraid, make the most of it !!! lol.

4th November 2013, 11:30
Yeah im a bit suspect of the front right brake now, it felt like brake fade (GEN1 Busas are pretty notorious for it) but then all of a sudden it came straight on. I was giving it a bit of lever so im going to call it operator error hahaha. End of the track seemed to be comming up awfully fast and panic braked once the fade started.
Ah well time to start fixing her! Lucky im a hands on sort of guy. All it needs is the brake light replaced (got a spare one in the shed) and a bit of plastic welding to get it road legal again. Im gonna have a go at plastic welding, doesn't look awfully hard compared TIG or overhead stick :shit:

4th November 2013, 13:55
What you did wrong?
Yeah you launched it just off idle (which is easy to write from the comparative safety of my keyboard).
But the crash? well clearly something was going on with the keyfob & that likely caused the imbalance pushing you off to the right. I think its probably safer to remove it.

You grabbed a handful of brake with a high tyre pressure that was cold?
Brake fade wouldn't have resulted in a lock-up, it would be the opposite.
how old is the fluid? If Dot 4 then anything over 12 months and you will have enough water in it to boil when applying brakes hard in quick succession.
The water expands with heat and this can mean your leaver is in a different place so brakes will come on slightly earlier than you expect.... might have been what happened?
I would have taken a few pounds out of the tyres myself. 42psi is for a Busa that is on the road at 100km/hr.... Not down a drag strip...
You would actually want your tyre to be fatter (by being flatter) for the stopping part... There is no need for it to be of a good shape to turn the bike in on a strip.... and it's completely usless for the launch other than weight on the front...
Next time remember to get the springs compressed before applying heaps of pressure.

Sounds like a warp or stuck piston to me. Over two stops (even from 140mph) in 5 minutes time, it shouldn't have any significant fade, no matter how crappy the fluid was, and for the one heat up I would suggest you riding back round to the front would have pumped the system back up. Perhaps the lever bite point grew with some temperature (which would be normal) and you grabbed it like the bite point was further down the stroke, as if the system was dead cold? Tyre temp would play a big part too as at that point after sitting it would be damn near dead cold and unresponsive.

Pretty much agree...no tyre flex, no time to warm, high pressure so narrow contact patch - all added up to a mess when a bit much brake was used. Although a disc bluing after just a few stops (remember you do 140mph to slow multiple times a lap on track so no excuses for fade over one stop per 5 mins...) seems a bit sinister, like something else is going on creating heat...
The Reibz
4th November 2013, 17:24
Had a quick look over the brakes, left one looks fine but there is still a bit of bluing on the right rotor. Will get it up on a jack over the next couple of days and give it a spin to see if its straight or not. Can't say I noticed anything out of the ordinary with it on the way home.
looks like there are going to be a few late nights in the shed ahead of me.
Thanks for the informative posts Jay and Quickbuck. You both obviously know a shitload more about these things than I do.

If one of your discs is blue then that would in turn heat up the fluid causing fade...... maybe you pulled a bit harder to compensate and the other disc suddenly took effect. A thorough strip down of the system is what I would advise..IMHO
And try launching around the 7/8 grand mark and using the clutch...... should results in low 10.s

On the subject of brake fade on a Gen1 Busa, I have managed 44's around Ruapuna on mine (just for shits and giggles) and it was good for about 4 laps before brakes were totally gone and I went motorcrossing- the occasional hard stop won't give you fade, that will only come with multiple hard stops in short order. (had braided lines not the OEM lines)
Just the once, wouldn't do it again, too f#^&king hard work and murders perfectly good road tyres, My race bikes are much more obliging (and a damn sight faster!)

Nah mate, tried launching at 8k earlier in the day and didn't like it when the wheel came up and the bike started drift towards the wall slightly causing a brown stain in the back of the pants. Hence why I took it easy for the rest of the day, wouldn't want to crash the bike or anything, oh wait....

Surprised no one tried to sell me one the moment I came back on the trailer. I believe Tony Grays gold busa was quicker than quite a few of the ZX14's anyway. That thing with the extended swinger and the straight through pipes was nuts though, forgot the name.

I was going to suggest a similar thing. During rapid heat up under heaving braking any moisture in there would effectively explode into steam locking the brake.
Tyre pressure just didn't help.

The problem you have is that you are on a Hayabusa, which is less a motorcycle and more a spa pool with two wheels and a seat.
But glad you are OK, never good to have a tumble.
At least it didn't land on you.
