#1:  Two riding questions. Helmet. Water Drops. (SOLVED) Author: 1986 XV700 Post Posted: Sun Jul 04, 2010 8:16 pm

These may sound silly or pointless but I've become curious lately.

(1) I've noticed that when I get behind at least two cars or pickups I begin to feel droplets of water hitting my skin at highway speed. At first I thought that someone was using their windshield wipers an washer fluid but I could never see any wipers moving. Next I began to worry that someone ahead of me was either dipping or chewing tobacco and I was receiving what they were spitting out. More recently I've decided that it must be water vapor from their exhaust. Any ideas or has anyone else noticed this?

(2)Can air pressure or or some other phenomena cause a riders head to shrink or helmet to enlarge at 55 MPH or higher? Almost every time I go for a ride that is longer than 10 miles my helmet get loose and continues to get looser until it feels like its about to slip over the back of my head if I let it go on. I can pull over and tighten the helmet and I'm good to go until I end my trip. I don't think that the strap on the helmet is getting loose because after I tighten the helmet the problem is gone.

A/C that makes the most sense. Now I feel real stupid?

Helmet foam. Sounds logical I guess I was focusing more on the hard Styrofoam and not thinking softer liner. willynilly

I agree with Mark about the water and if your helmet is not old, it is probably too large to start.
If you have 1/2 helmet, they kinda just sit on the top of yer head so I'm not sure about fittment.
If you have a full or 3/4, a properly fitted helmet should not slide when you try to rotate it holding your head still. Many people think a properly fitted helmet is too tight when new.

I think the real issue is that its a half helmet and like Mark said the foam probably gives. It fits snug and I found that if I wiggle the helmet while pulling it down then cinch the strap tight I've got a 75% chance of not having any problems. I assumed this might be a common issue with half helmets because they're more of an airfoil than the others. My full helmet gives me no problems.

my helmet does that sometimes(Skorpion EXO-200). it's snug when I first put it on and if it's real windy (gusty) by the time I get where I'm going it's kind of loose.
reckoned it's like "memory foam". confused

Water spray behind most vehicles is probably A/C condensation as everyone mentioned. And behind many larger trucks, there is also the water spray regularly kicked out of the brake system's air tanks to keep excessive water purged.

Unfortunatly, there is another possibility other than A/C drainage and air-tank purging if you're behind an 18-wheeler. Two close friends are long-haul truckers who will tell you the majority of such have been "rigged" by the truckers to keep from having to make so many restroom pit-stops. Simple device consisting of a large funnel stuck into the end of length of 3/4" ID tubing with the open end stuck through a hole drilled in the floor of the cab. Funnel end is easily moved around akin to an old ship's voice communication tube while the other end sorta works like the A/C drainage line Rolling Eyes

Scooter windshields and helmet faceshields aren't just for rocks and bugs eek

Dang it EB, now I'm thinking about all the times I've felt the moisture on my lips. I've never licked them though, now I guess I never will again. You have given me a good reason to kiss the wife when I get home.

Got a bubble for my half helmet and it solved a bunch of problems, not the least of which was the five-pound grasshopper that smacked me right in the face the other day. That would have been ugly had I not been wearing the bubble. It solved the problem of the helmet wandering around, too. I wasn't very sold on it to begin with, but it's grown on me.

Thanks, for the tip.

Got caught in the rain this evening. Had to ride with my left hand shielding my face from the rain drops. I swear there was small hailstones in it, it felt like needles being driven into my face.

Think its time to call this one solved.

I do appreciate all the thoughts tips and useful info.

On any given day, my helmet grows or shrinks in inverse proportion to my ego.

I am a frequent 'bacco chewer so I can't tell if it's coming from ahead of me or if it's my own swill..
