John, I always ran my ST4S at 32F/36R unless on track when I dropped to 30 F/R. I always found the ST4S would feel a bit 'vague' on the steering with higher pressures.
When we were racing the TZ250 that ran at 36psi F/R-HOT-straight out of the warmers. Those pressures are on slicks and with a bike weighing 103kg don't forget.

I recall a Pembrey meet where they were a fair bit higher than that John

Poor WJB found out the hard way

Thanks guys.

Hopefully the ST won't be doing any more trips if the new MS1200 turns up in time. If I do still use it I'll try your pressures John.

I'll run the MS at the pressures specified in its manual and see how I get on.

Thanks again.

True-but then he was the one who set the pressures-or rather didn't check them.....................3 times he chucked it down the road that weekend-first race meeting-talk about a baptism of fire.

That has to have been one of the worst meetings ever. Sleeping in a puddle in a tent. Strong winds throwing peoples gazebo's down the paddock. Rain and dry in the same race. Slicks or inters or wets. You working half the night to fix the bike. Holbeach changing to the inters tyres and as I now know, he always over-inflates to get the tyre to seal properly, but some idiot (me) tried to make a change 30 seconds before the race and didn't check and after falling off at the fast right hander checked to find the tyres at 45psi. To be fair the other off was on oil and I was not the only one to go down on it. Can't recall the third off, maybe that's a good thing. That was a long drive home eh

Happy days

for years i ran 32-33 in the rear of my S4 and m750 and 30 in the front but recently have been putting 34-35 in the rear and 31-32 in the front and it has improved both bikes ,they turn in and hold lines much better.
