Wasn't sure on if it was you lot or if you'd left as we got there pretty late due to the snow (or rather, the pinlock helmet i bought from mmc the day before being wank and steaming up worse than than the windows in a thai brothel.) I'll pop over next time haha. Thought i recognised @antzx6r tenere as we were leaving.
Pete, re the pinlock. Try adjusting the screw head pins. On mine they're like a cam and can adjust the pressure between pinlock visor and proper visor. Worked for me.
Took it back seeing as i was there anyway, they set it up again and it was just as bad on the way back! I'll see if that helps when i get home, cheers Paul.
Just one other thing. If you fit the pinlock in nice warm moist air, when you go outside into the cold the moist air inside the pinlock will condense. In short,fit it outside.
If you look carefully you can see the line where the bead compresses. It should be visible all the way around. If not have a play seeing if the pinlock needs moving up or down or if it needs more or less pressure using the adjustable posts.
