How and why

[Ivan]

looks like the tire presure is to low to me
we where running 26 psi on the tt900's

then a tire presure gauge whent faulty and was reading double
the tires chewed up like that but all over
I'm guessing there was some riding around after but not at race speeds ????

try going up in pressure and see what happens
22 psi seems a bit low for a road tire
but better for 125 gp slicks

yeah but conti run a completly differnt carcass to the tt900 they are designed to run really low pressures.

Is that a 120/70/17? off a front tire?

and for everyone thinking I ment buy a rear shock I ment completly different

What I ment was Robert Taylor has alot of knowlege on setups and would be able to see the pic and lead you in the right direction of what needs doing, NOT BUYING A SHOCK but saying maybe oh add more pressure here or less there or more preload etc.

Thats possibly the only way to fix the problem properly is get an expert who knows what they are doing to give you advice he is a real approachable guy

Ummmm "Too much throttle, you nickum poop" Slow down you loonie!!

[R6_kid:Me]

lol @ trudes!

im 110kg and my bike has far less sufficient suspension, tyres and frame geometry to yours. My tyres are balling up on the edges (TT900's) but in a much more predictable way - only on the trailing edge of the tread.

Try something like +4psi and then do a 6 or 7 laps, take a look at the tyre, do the same again but -4psi on the original. You'll soon know which way you need to go.

Do you guys run a practice day before racing?

This is my rear tyre from Roys Hill, Out of the many experts out there can anyone tell me WHY this is happening and a possible fix for my 11hp tyre shredding monster

Thanks Fishie

Is the tyre actually working Fi5hy? It would apear to be from your vids. If so what's your problem?

Edit: like Sketchy said that tyre has been cold torn in another life, once they've started it can't be stopped.

Once the tyre starts 'tearing' which is what it was already doing before you got it, it wont stop.

Also I believe that tyre was one of the first Conti Race Attacks which seemed to struggle with tearing but they have got them well sorted now.

Chuck that other tyre you've got on and see if it's better, or otherwise after this weekend I should have a new generation Conti Race Attack you can use. The new ones are fantastic!

As for suspension on a bucket, as long as there is some sort of damping activities happen within the shock, then it's 'sweet bro'

I agree with Sully. From what I have seen you are riding the wheels of that thing and kicking ass. Something has to where out. I have a rear dunlop you could try if you want.

Bloody Hell a trye per round anyone would think I'm getting sponsored or something?? Thanks mate but I'll try the next one on the pile.

Not to far from now, I should be fully race fit for the start of March, hopefully

1. Tyre pressures. Increase Your tyre pressres by 2-3 PSI. Optimally You should run your tyre pressures as low as you can without the bike moving around. I'm 100kg and only run 20PSI in my Dunlops.

2. Suspension. Hold the bike upright. put both hands on the top of the tank at the back near the seat and push down. The front and rear of the bike should move together, about the same travel Start by setting about 65mm fork travel and go from there

3. Do you Weigh more than the bike ?

Whats this "cold tearing" thing you guys talk about?

Whats this "cold tearing" thing you guys talk about?

A tyre is somewhat fibrous in it's internal construction. If you stress the tyre before it heats up to optimum working temperature, the fibres begin to separate. This is obviously non-reversable, and because the process has begun and weakened the bonds in the fibres, it continues regardless of more careful subsequent treatment.

So if you were to go out on a trackday and accellerate a little too hard out of a corner on cold tires (probably not a good idea anyway, I know) it's possible to ruin them?

Yes. Along with the fairings, barends, pegs and footlevers...
