Just got my nice new TSR flyscreen.
I have worked out where everything goes, good start

But I have a couple of questions.
Do the clamps that fit in the mirror fixing points go inbetween the mirror bracket and head or under the mirror bracket?
Also whatever way I try the bolts are too short, they are 20mm long, not quite catching the thread in the head. The clamps about 10mm wide, but obviously tightens down a bit to hold the support bars for the screen. So do I go for 25 or 30mm bolts?
While I'm here, I also bought clamp on crash bars for the front mudguard, however the grub screws seem to short to clamp up, they are 10mm long, am I doing something wrong or do I need longer screws again?
Also is it worth using anything between the grub screw and the mudguard to spread the pressure so as not to deform the mudguard?
Cheers for any help.
