I zip-tied the mesh in multiple spots, then used this stuff: http://www.createforless.com/Loctite...utm_medium=cse
Probably not the best stuff, but held well without having to surface the plastic. ~I usually leave the zip ties on for a week
Here are some pics of the CRF230L fender I vented. Even though I don't have the cooler there anymore, I wanted to see if it made a difference in cooling by possibly getting more air to the head. Didn't notice any change in temps.
(You'll see the adhesive in the last picture)
