I only use factory forks in my bike.

You two are so nasty to me

Thanks for all the answers guys... I'm 99% sure the disc is fine. I haven't crashed yet so I can't see any reason why it would get warped... I had warped discs last year and the feeling was totally different...

I think my problems started when I did the 2 changes below (unfortunately I did both in the same time and so don't know which one could be the cause of my problem):
- fitted a 6.5kg spring to my Ohlins rear shock (instead of a 7.5) following the advice of a mate.
- fitted a pair of jacks (built by Rich @ Louigi Moto) to raise the rear of the bike.

Anyway I'm not tired, so I'm now off to the shed taking the forks apart, I need to see what's inside (I've even been suggested that they could be empty of oil in regard as how they behaved in static... ).

6.5kg sounds a bit on the light side for the rear spring Tonio, I'd have said 8kg would be about ideal. could you try putting the original spring back on and see if that improves it? I would have said raising the rear ride height shouldn't cause problems under braking particularly, of course I may be wrong though!

Whilst you have the forks apart, measure the springs - outside and inside diameters, free length, and also the length of the spacer tube. The springs I have may well fit.

[Tonio600]

Right, a few things which may speak to you more than to me.
First, the lenght of the forks I was using at Cadwell, I have absolutely no idea of if it was "bottoming" or not...

The leaking left leg...

And finally, even if Dr AK is always saying "read your tyre you numpty" I never think about doing it. So I just had a look at the front tyre and I must reckon I've never seen it being so worn in the middle and with so many wrinkles...

And

Which still makes me think I've got a suspension problem rather than a brake problem. Off to the shed again, now I'm starting the surgery bit

[Jon]

Tonio are your forks always that mucky? only I'm thinking leaking fork seals?

[Tonio600]

Yes Jon, the left leg is always leaking

[Tonio600]

And finally what I found in the left leg:


Zimbo, dimensions of the left leg spring are 280 x 35 x 25mm.

That's it for tonight, after all Cadwell is in about 6 weeks
