Hi mate, I have been to a few of the recent burrows days myself. Great fun. I first went out with 36ish all round on Dunlop Direzza star specs (road legal semis) but was told by someone with a clue that that was too high so I ended up using 33 front 31 rear - thats cold. To be honest I couldn't really feel a difference - probably because I'm an amateur.

Enjoy the day. I will go to next months I think so try and get there for that if you can.

Cheers

Bob, KU36 are not proper R specs so don't be tempted to use too low a pressure. The "right" pressure depends on how hard you're working the corners. I'd recommend you start with around 32-33psi cold. After your first run have a close look at how the outer shoulders have worn, especially on the right side, and run your hand over the tyre surface to get a feel for the temperature profile. If they're feathering over the shoulder and they're hottest on the outer shoulder of the tyre surface, increase the pressure. If they're not wearing to the shoulder and the middle of the tyre surface is hotter than the outer shoulder, you can drop the pressure a little. Good luck at the BDD.
