With road tyres it doesn't make that much difference - they're designed to work in a wide range of conditions. With race tyres it definitely does matter.

they are road tyres.....just used on a track.?.............

Indeed - so I am saying it probably doesn't make that much difference with the Diablos if you are a couple of psi one way or another. In principle though, you should run slightly higher pressures in the wet for the reasons I outlined

Could run them flat in the wet for all I care

[twpd]

Yes. Well we all know:

1. You don't race any longer.
2. You're a shandy-drinking southerner.

Only one of those is correct.

But as to the wet racing, I'm gonna buy the dsc as everyone has their price and I am a billionaire, I'm then gonna ban wet racing.
Remember your wet lap times are directly linked to your IQ so the lower your lap time......., stupid is as stupid does

agree on that sire...........

[twpd]

Nottingham is south...a long way south. of here. So you are a southerner in my books.

Re. IQ...I'm ok here....I'm getting more intelligent with age You should see how SLOW I am these days.

Zimbo:
My thoughts on your post, I could be right I could be wrong - cue Jonny lol

You mention:
" ... instant loss of front traction and down so fast I don't even remember what happened..."

Assuming you're not accidently touching the front brake lever causing the front to wash out, when its wet then the tyres are much closer to letting go due to lack of adhesion, and when you're cranked over entering a corner it wouldn't take much lever pressure to cause this in the wet, and we've all tensed up some point when experiencing a big moment on the track.

Then could it have been after you rolled off the power entering the corner (or even just after this) in which case it maybe down to your front forks being either too hard or too soft ie not very compliant.

How's the balance of your bike at the front when off the power ie when you throttle off at the end of a straight does the front end stay still ie too rigid, or does the front end fall away and you loose the feel of the wheel thru the forks ie too soft, or does it just dip a little but you have confidence in it and can feel what the tyre is doing?

Also whats your engine idle/tickover speed?
1500, 2000, 3000, 4000rppm?
Can you adjust the tickover/fast idle whilst riding the bike (I've put the fast idle lever back on my bike for this reason - eh Tonio lol), try changing this out on track to a setting that helps your front end settle better when getting off the power (mine's ~3000-3500). I find in the wet that the tickover can really help in the balance of the bike off the power, it also helps in the dry but not to the same degree as in the wet.

Cheers
Glenn

P.S Anyone want to buy my bike? lol

As for your donno crash Zimbo I was right behind you. It appeared to me to go down as soon as you hit the front brake, I thought wow he's braking late..........
