Thinking of drilling a hole in my sheild.. - Motorcycle-Journal Forums

I am thinking of drilling 2 small holes in the sheild on my full face helmet.

Purpose. Well, I want to allow more air in and stop the build up of fog.

Does anyone think this is safe? If not, why?

If it's fogging you're concerned about, why not just use some fogtech?

I'd be concerned about the possibility of whistling or other noise with the small holes in the visor.

..drilling holes might weaken it and you will find it cracked someday.

Try this instead.... I took a small piece of black plastic tubing and split it lengthwise... cut two pieces of that about an inch long...and pushed them onto the bottom edge of the plexi a few inches apart. You cant see em but the shield wont quite fully close...so I get a bit of air in....and that way you can take them off someday if you want a tighter seal.

Hey ! maybe I should make a kit !! LOL

I've gotta agree with Annie here. Any holes you put in the shield or helmet will reduce the strength of that part. It'll be more prone to breakage. Use some anti-fog stuff or get a lid with more ventilation.

What kind of helmet is it, anyway?

I agree with the others. Bad idea.

Mine has a "notch" when you open it about 1/4-1/2 inch so that it will stay there. Open yours slowly; you might have one too.

Thanks for the replies. I am going to get the plastic tubing and put it on the bottom. I never thought of doing that which is why I posted the question.

As for the brand I have, its a HJC.

I agree, don't drill it. Try putting a little bit dish soap on the inside of the shield and buff until clear. It also works for glasses.

HJC's have the notch about a 1/2 inch open. Mine does.

Took the time to close it slow. Found the 1/2 inch open before sealing.

Man, you can't take anything about riding for granted. Except its fun.

Glad you found it. I use my half helmet for summer riding but when it gets colder out I use my full face. I usually leave it at that 1/2 inch opening to defog, then close the shield all the way when moving more than 15mph or so.
