I am on 11-2 as well with my blue FZ6 and my lad on his Blackbird and a few other mates from Wales
I think they are happy as long as you wear decent kit with armour
They are hot on exhaust noise and there is a sound check at 2/3rds redline and 105db. Apparently some new bikes with OEM exhausts dont make it but a Fazer with standard is OK
To be honest, I wasted my opportunity last year as I ran behind tail end charlie the second instructor and couldnt keep up. The pack of about 20 bikes goes out with two instructors one front and one rear. They set the pace to warm your tyres and also show you the lines but the pack gets so strung out with no overtaking that some are half a lap back and no idea what the line is. If you can get to the front of the pack even if you wait for the next pack to go out. There is no timespan for when you go for your slot really.
After a couple of laps they allow overtaking with the faster guys taking the slower ones only on the straights- no-one will overtake you on a bend as there are cones for that and braking points
It is all explained at the track briefing which you have to attend or you dont go out.
Hang around the fence and watch the others go round and if you have a camera take it on the bike but dont have a flat battery like mine :'(

To get an idea of the track- this is 15 minutes and it is all over way too fast
I had never been on a track before and started off riding like on the road rather than ragging it- maybe I will be quicker this time. I guess relax and enjoy
