....that by cracking the visor, I lose the sealing effect at the top of the visor where it contacts the upper edge of the eye opening, causing a bit of wind noise.........
My Missus & I run Shoei GT-Air's with Pinlocks, & for somewhat similar reasons, we both tend to ride with the visor cracked open on its first detent with similar issues, plus the fact that whenever we are riding in the rain (which we do fairly often when it's raining here!! It's pretty much either drought or flooding rain where we are!) sometimes we get drips down the gap betwen the helmet & top of the visor & onto inside top of the visor, from where they run down across your field of view, & occasionally those drips end up between the visor's inside and the Pinlock screen! The effect is sorta like what you get from sneezing inside a sealed helmet! And I can tell you that
THAT is bloody annoying, but
veeeerrrrry slightly less annoying than fully closing the visor & ending up with our heads encased inside a steam bath!! :shocked:
Anyhoo, you've probably got the gist of the problem.... it hasn't been exactly 'cheap', but I've tried trimming the visor just a tiny bit shorter - that failed due to too much wind noise & rain ingress; then I had a go with adding a small strip of black tape across the inside top of the visor along the lines of the 'sun-shield' that many use, affixed so that it seals the top edge of the pinlock
and provides a sun visor, & that sorta works, but it still leaves enough of a gap for some rain drips to end up on the inside of the visor/Pinlock screen! Sooo, my latest attempt has been to fix a small strip of high density foam (actually it's thin door seal draught excluder stuff) along that top inside edge of the visor.
So far (it's only been a month or so, but it IS our winter!) it's been working FANTASTICALLY!! The foam is barely 1/8th of an inch thick, runs right across the top inside edge of the eye gap in the helmet, & it lets the visor be 'fully closed' rather than leaving it cracked in the first detent position, but the thickness of the foam is just enough to hold the bottom of the visor open sufficiently far enough off 'fully sealed' that it lets sufficient air circulate & fully stop the 'steam bath' effect - and better yet, there's almost NO extra wind noise!! AND we get NO fog, NO extra wind noise & NO drips or runnels of water making their way into the gap between the helmet & the top of the visor!!
Still in the testing phase, but so far, the outlook is good - without any extra wind noise or rain making its way inside! :thumbup:
