Track Day advice.

[Allan]

Actually Allan, this is no longer true thanks to those who ran raves years ago.. New legislation was brought in to stamp down on such terrible goings on !

Sad to say the laws have far reaching affects.

Jaws, I beg to differ old pal.
I can assure you that if you are pulled and your tyre pressures checked and they are found to be wrong, you can be prosecuted - I'm not saying you would be, but could be (espically if I'd got out of bed the wrong side or didnt get a shag that nite)
It matters not that you may have just left a track event where you have been fiddling with your tyre pressures, its your (the rider/driver) responsability to ensure your vehicle is in a road worthy condition for use on a public road.

"Er NO!
On the track (and I mean a proper one) riding a Blackbird You should be running 31psi at the front and 30psi at the rear. "

I beg to differ here Ben but did 'tell'
This is quite clearly a tell and not a 'in my experince' so where's you ACU licence, your proffesional qualification and your 3rd party insurance liability?

Admittingly, I only have the later two, but even I would'nt spout off telling folks what tyre pressure to use for fear of being sued when it goes tits up.

You might want to 'think' before posting.

Ok , so if I didn't explain in my first hit about trying a low pressure and then adjusting it after warming the tyre up , I sure did in other parts of this thread.
I never stated 'I' was a professional at any stage but did post that these where the pressures advised by experienced people and/or instructor for a track day company/racers.
They have ACU licenses and I never stated I did.

So - first off bert states 42/42 as being important (and this on a TRACK DAY thread)....so what's his advise and where are his credentials. Same as mine I suspect.
So did you tell YOUR pal bert that he "might want to 'think' before posting."

You said "This is quite clearly a tell and not a 'in my experince' "
Well - It was my experienc, I did run 31/30 and had no problems
and as I pointed out/infurred in another part of the thread, If the weather and temprature of the day was colder I would probably start at a higher temperature, run,check and alter to suit.
My point has always had scope for adjustment where as bert just stated thet 42/42 was the Bee all & end all.
admittedly as I've just said - I should have talked about adjustment in my first entry into this thread but as you can see, I've mentioned it later.

So now that you & burt have insisted that everyone using a Blackbird on a trackday would be wrong to use anything other than 42/42...Can I sue your
ex-rozzer ass when I come off the track?
No , I wouldn't have thought so. ,,,/,

Very good Bert,
do ya think it has solid tyres...if so maybe i can use that for Brands,
may even get a quicker lap time in...

 

[D.S.]

That would be great.. I shan't even ask what tyre pressures you'll be running.............

Now, any chance of some advice other than tyre pressures, or is that all peeps seem to know or care about.... :}
tyre pressures to bed me thinks!

Paddy, I'll see you on the day, but my advice is if you want some advice based on experience, best post here http://www.visordown.com/forums/forumdisplay.php?f=40

It's supplied with SOLID rubber boots so pressures won't be a problem!!

Didn't know he was an ex-rozzer; :dunno: explains a lot :}

 

[Samster]

So if you wanted to you, you could prosecute a biker for running incorrect tyre pressures? So what do you do, wait 45mins until the tyres are back at ambient temperature? Ridiculous.

I think you'll find that most would tell you that they must have fallen foul of the poorly calibrated air line at Sainsbury's and tell you to go and prosecute them...........

I suppose that when the cops have just made arrests and have 3 in the back of their patrol car they go straight to the garage and adjust their pressures in accordance to the manufacturers recommendations? Bollocks do they!

Sam
Some things in life are not so clear cut and the law is often left often to 'interpretation', but something?s are very clear.

If it means that you have to wait by the roadside for 45 mins for evidence to be gathered, then you will wait. If you try to bugger off or become obstructive, you may be arrested for that obstruction.
When being breathalysed, there has to be a 20 min gap from the time you had your last drink to being bagged, so if you have just left the pub and are pulled, then you WILL wait 20 mins.

I suppose that when the cops have just made arrests and have 3 in the back of their patrol car they go straight to the garage and adjust their pressures in accordance to the manufacturers recommendations? Bollocks do they!

Of course not, that would be plain ridiculas, being the professionals that they are they check oil, water, tyres, washer bottles etc BEFORE each tour of duty.

Ah well Allan, better sue the folk who told me and thought this....after all they aren't ACU holders.
I thought this info was correct as they ride birds but don't do track days.
My mistake.

No problem Ben, anyone can make a mistake, but it does make of case of not listening to others.

BTW, for your info, I'm booked on a TRACK day at Donington on the 16th August, but I'll be on Ron's bikes, not my Bird, does that count as doing track days?:dunno:

Come and have a look if you want to.

16th! your only doing it on that day so you can't come and play at Brands with me & Paddy.
Ya spoil sport

On a race track, not being told your going too fast & ya on a Ronnie bike....yup, lets call it a track day :yo:

LOL !! Ya daft old sod Allan !!

You aint differing at all .. you are completely agreeing as I agreed with you ! LOL !!!!

What I am saying is that it is actually possible to be nicked for tyre pressure whilst ON a RSID, thanks to the laws brought in primarily to cover raves..

[PsychoBikerBen]

Right then,
Here's a little bit of info supplied to me by a guy from another forum.
I'll...er leave it up to you to decide if his experience/cridentials are good enough, eh?

"I had a good read through ?that forum? and there is some seriously dangerous advice being given by ?those in the know?. My apologies in advance for a long post but I find it very irritating when posts like this are responded to so badly.

First of all, your tyre pressures are determined by a number of factors but only have one single objective ? to create the correct contact patch for the tyre and the riding conditions. As a general rule you will need to reduce your cold pressures for track day riding. The amount will depend on the circuit, the weather, your riding speed and the increased heat in the tyre.

Running higher pressures will cause you reduced grip and may lead to you crashing.

Running lower pressures will not cause your tyre to delaminate and fail, as suggested by someone on that forum. Your tyres are likely to stay on the rim at down to 5 psi but will start to creep on the wheel. I have tested this under controlled conditions with a tyre manufacturer. Last year I did a full race, by mistake, on a 5 psi front tyre and it stayed on the rim. The bike did not handle well, was just ok around corners but was really bad on the straights.

Take Sarah?s advice and you will be ok.

Mike:
-----------------------------------------------------------------------

Now for the boring bits, especially if you want to respond on the B.I.R.D. forum, based on some of the comments there about the experience of the posters. Please feel free to cut and paste this on that forum as I can?t really be bothered to register myself.

Dunlops recommendations for Blackbird tyres:

For ROAD USE
Front: 120/70-17 at 42 psi with a maximum load of 520 lbs
Rear: 180/55-17 at 42 psi with a maximum load of 805 lbs.

For TRACK USE (on the same tyres above)
Front @ 28-33 psi
Rear @ 26-33 psi

WARNING (from Dunlop):
Motorcycles are sensitive to tyre combinations. Use only those Dunlop tyre combinations recommended in the Dunlop "Motorcycle Tyre Fitment and Pressure Guide".

Before fitting tyres to a modified or converted machine it is essential to consult either the machine or tyre manufacturer.

The fitments shown in this guide are intended for use in the UK by an average solo rider of 65Kgs (143 lbs) and a machine to the manufacturers standard UK specification. The cold inflation pressures shown are the minima for safe vehicle operation at these service conditions.

For sustained high speed use, the carrying of pillion passengers or the carrying of heavy loads the cold tyre inflation pressures should be modified in accordance with the vehicle manufacturers handbook for that particular model.


Can?t really argue with the manufacturers guides can you?

Also, to justify some of my own experience, in case anyone on that forum wants to argue with you:

30+ years riding motorcycles
Around 500 000 miles on the roads
ACU National racing licence holder
Ex FIM International racing licence holder
13 years racing experience from club to British Champs & international
Tyre development testing on road and track for one of the major manufacturers
Racer training instructor"
