Check your tyre pressure.
Could be or maybe your suspension set up, or lack of it?.... Does it even make a difference on such a small bike??
Or it was just plain hot. 47 degrees apparently that day!

that is a conti isnt it?
Conti have a wierd tire pressure set up.
What pressures are you running
My Conti Race Attack Rear i run 24PSI and 28 front.
If Pressures are fine then its probably a suspension issue best bet is contact someone liek Robert Taylor he would be able to tell you what is going on.
But maybe more preload on the suspension?

Had 22 psi in it on instruction from Andrew L
As for Robert T mate its a Bucket ( the cost of a shock would be 8 X the price of the whole bike)

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

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?

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

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?

I was watching your machine, Fishy, when you and Bayden were tearing around at the end of the Roys Hill day.
Your machine was moving around quite a bit in the rear end while you were cranked over, especially at the fast left hander just past the entry to the pits, ie like a lack of rebound damping.
Just my 2c worth.

To be honest Fishy I've never seen another tyre on your bike do that so I'd suspect it's the tyre itself.You were moving bout alot up Roys Hill when most of us were havin less trouble .I take it you didn't change anything else when you changed the tyre? if not it could be the tyre is just NOT of their normal standard.

Mate the bike was scary though there, There's a bump on the entry that upsets the bike and it gets worse when your off the throttle so the only way was to keep it pinned (went well) off the gas (Fuck). As for rebound it doesn't have any.

Your right mate but the Contis are Fuckin good tyres but maybe not this particular one I've put a Second hand Pirelli slick on so it will be interesting to see if this helps.

Yes.
In simple terms MSTRS is correct, however in practical terms this is very unlikely to happen with a bucket.
You actually have to ride reasonbly hard to get heat into a softer compound (race) tyres. It can be quite a balancing act at first, acceleration and braking are the the best ways to generate this heat. Doing this with the bike relatively upright is the safest way . It's not a good idea to try an ask for too much side grip untill you've turned a couple of laps and taken the opportunity to clean the tread (that's the reason you see racers weaving on the start finish straight at the end of the warm up lap, most of the heat is generated when they speed up and slow down).
You're highly unlikely to initiate cold tear in a tyre on a bucket. Being relatively light and slow they simply don't generate the forces that anything bigger, faster and heavier can so the tyres get a much easier time of it. In my ten years of racing I've never seen a bucket cold tear a tyre and the vast majority of that racing was done in the winter.
Please be aware that this tyre was probably used on a 600SP bike (I'm assuming JayRacer37 had something to do with that?) and it actually showed signs of tear before Fi5hy started using it. I was going to point that out Fi5hy but you don't need any help from me!:bleh:
BTW apart from the tear how does the 120 work on the four inch rim Fi5hy?

Mate she seems to corner ok but out of the last two tyres i haven't had any side grip so at the mo I'm not sure if the 17 is doing what it should. Might even try a back to back with the 18 at the next meet

Just a thought.
What size is the tyre?
What bike is is running on?
What is the gap in the swinging arm for the tyre to run in?
How close to the swinging arm does the tyre fit?
If it is really close then surely when you are riding the bike then the tyre may be expanding outwards and rubbing on the swinging arm.
As I said

Never mind down to the local bike shop for a look thought the spares bin and guess what their was one there with shock in toe as well. So the hole unit (linkage and shock) bolted on at the right price (Free) with new rear wheel bearings($60) added in as well.

No the front was ok at the start to about mid race then the back tyre was balling up so much that in the end it felt like cornering with a knobbly. The vibes though the bike on full lean was incredible. know I now what the motogp boys are on about:scooter:
saxet
14th April 2009, 21:06
Ok what about tyre balancing? It still could be compression or rebound damping not at the optimum causing an oscillation when cornering or due to small slides setting up the vibes.

14th April 2009, 21:12
balancing yes could check that as for rebound and damping it hasn't got ether

F5 Dave
15th April 2009, 17:54
odd thing is preload is apparently low & there is like no static sag. I thought it was just because the preload was too high or something is siezed, but new bearings & another shock. It is quite odd. Have you checked to see if it is bottoming out when cranked down? Seems like heaps of room but. . .
Still seems odd that there is no sag whatsoever. even my 50 can be adjusted to have some static sag & the back end is really light. The 17" tyres keep doing it, so why? Is the change the cause for some reason or just a red herring & you haven't had as sticky tires. nah 3 diff tires. If that rim is severely out of balance or round you should be able to see it pretty quickly.

For what its worth:-
The very fast guys at Mt Wellington run 18 psi F & R in their slicks. Any more and they don't get up to a good working temperature.
There is a temperature where slicks work best, about 55 degrees C and when they are working well they feel a little sticky to the touch (from the oils in the rubber which makes the rubber complient). If they are over inflated or cold they can get the shreaded look but arent so sticky to the touch.
Fi5hy corners as hard as an RS but his all up weight bike+rider is much more, overloading cold tyres? and just ripping the rubber could that be possible?.
Just another idea for the jigsaw.

Someone Else said the same thing about 15 to 18 psi I have one more 120/17 left to try. I might try it at that psi and see. I have got someone trying to track down a shock with a bit more adjustment.
Thanks for the input

15th April 2009, 22:21
Kiatoke is mostly R Hand corners. If you have a tyre thats cooked on one side, (I know its not the done thing) but for the sake of economy could you turn it around and experiment with whats left of the good side.
Start at say 22psi cold do a few laps, feel the tyre, lower the (now hot) pressure a psi or two, no need to measure it, just let out a puff. Do a few more laps, feel the tyre Etc. Etc. down and down slowly.
The tyre should go from cold dry and torn to warm, sticky and working well, and if you over do it, to melted and squirmy on the track as you lower the pressure. When it feels good, warm and sticky, measure the hot pressure, let the bike cool of, measure the cold pressure and there you have it.
Team ESE made a mission of doing it this way at Mt Wellington one day, and found 15 psi cold was generally to low for us and 18psi cold is about right for me. Others have slightly different preferences, a psi or so cold makes a big difference. Later we found some days the weather was to cold and nothing worked.
Kaitoke being a longer faster track I started at 20psi cold but the tyres never got the warm sticky feel that I was used too, I never got them into the zone all day, and they never got the Mt Wellington look, tricky things tyres and suspension.
Good Luck.

This may have something to do with it?? What do you think
I think you're making excuses now. It's definitely the Long-chin engine and aggressive rider that's doing it. That swingarm is nothing to worry about.

Ya think??
I can snap it with my hand but its easier to weld when hanging on to something

Yeueew! That's bad. But that is a symptom of the dreadful vibration I would have thought. Possibly from the tyre chattering.
Possibly from that Diesel stationary pump of an engine.
So that is on the cush drive side. What is the cush drive like, pretty sloppy? Solid?
More so I see a tailpiece of the 50 in the background. Need to have that up & running for when I get back in action (whenever that is). Seals are easy to replace, I have a small window of time I could help if uncertain of split.

Very slowly scrub it in, looks like rapid changes in temperature.
Very heavy dumping and power out of corners i'd say.
Have you tried doing a few big slow weaving before putting the pace on?

Cush drive fine sold as
As for the seals all I need is the flywheel puller to do the job. Seals have been ordered just waiting for the call from Fat Mac

The RG150 flywheeler puller size, aint that usually sized one. Its a fucked up version.
Probabaly too big. Unless the flywheel is off an RG150.
Otherwise, skunk has that "standard 90's jap flywheel puller", what seems to work on anything bar a RG150. (Too small).

Yep, I do. Wouldn't let it anywhere near a 'diesel pump' though...

I Have the fix almost done I have a choice of three rear shocks one standard one NC30 and one ZXR400 the NC30 raisers the ride height by 20mm and the ZXR 400 by 43mm so not to sure which one to fit. Also had to mod the swing arm to fit the bigger shocks and of course weld up the broken bits. In the end the swing arm was broken in six placers!. I have also found a second standard swing arm to try just in case.

Shit, does it even need flash shocks now it has a working swingarm?
Only one real way to find out which works the best...

Well then had my first run today with the new set up and the tyre looks sweet after 40 laps of Kaitoke I started the day with 18psi in the rear and after 10 laps the psi went up to 22. No cold tearing!!!! Played alot with the sag and the rebound shock to feeling good and for the first time this year I haven't eaten a tyre.
Do your sprockets line up now?
