I'm wondering if the front feels skittish due to the ride height, not the tyre pressure.
By the way, you need to look at your figures again - 2.8 bar equates to 40.611 psi (at sea level just to be pedantic).

Yes l can't wait for my linkage to come back, so l can play with the settings, l assume when l lower the rear wheel this will put more weight on the front wheel, so l will then need to play with the tyre pressures as well

Will let you know how l get on

It doesn't affect the weight, it affects the head angle.

Only just seen this post as I have been away.
Ride height-as stated by Nelly, rear tyre just kissing the ground when on the stand works for me, the bike will tip in much more easily and you won't need so much bar pressure or lean off to make it turn. I always run 34F 36R pressures-but it's a personal thing tyre pressure, some like them harder some softer. No way does an ST need a steering damper, I have had my '4S from May 2001-it was one of the first delivery-and have done 34,000 miles on it, lots of which have been 2 up with full luggage. It has been to the foot of Italy, and the Arctic Circle, been round the Nurburgring, and used for instructing on our trackday-basically a brilliant bike.

Update, striped the alloy thread trying to get the ends out of the alloy linkage rod, 10 day wait for the part £30.00 for the alloy rod, the steel ends are Ok, but if l needed them, they would be £120 each end

So bikeless for the bank holiday weekend, and the weather looks good

Hope l am all sorted for Cadwell Park

No parts available at the moment so put the old strut back on, l use PTF tape as there still just seems enough thread left, but would not be that confident if using it at Cadwell especially if the rear leaves the ground
So l hope the new one gets to me before then.
Yes it does speed up the turn in, but it felt stiff at the rear end so wound the the preload out 2 clicks,now not too bad, but it pitch's a bit over bumps, so l have email MD Racing to get it set up properly for Cadwell

Also need some new tyres, any good deals about looking for BT016's or perelli Corsa 3, or consider something else if there very cheap

I know its a personal thing but when i had my st4s to go to WDW2007 on i bought Bridgestones at the fitters recomend.
Never again, they really did not suit the combination of the bike and/or me. Wore out quickly, didn't like the cold in switzerland and generally were not a patch on 208rr's. Yes i know they are not meant to be touring tyres but waaay better then These.

I seriously wish i had not sold the ST either , big mistake.
