They're fine if you have additional venting, beyond stock. The hood gets so piled up with pow that those vents become pretty useless on deep and slow days with or without frogskins. If you're gonna melt, it won't be just the frogskins that cause it on those days. You get way more air from the lower front openings than through the hood, anyways. Frogskins help keep water and debris from coming though the top. My experience with and without them.
If you block the lower front holes, add frogskins, and don't add additional venting, you are turning your motor into a rotisserie. Don't block the belly. Add more vents or a blowhole. Frogskins will be okay.
We seemed to be struggling with poppin belts up there .......some of our canadian friends up there discussed as g-man stated........they believed that ultra fine powder gets in and causes the belts to slip and heat up on a very small scale but consistently doing this obviously not good. We all vent our sleds a bit also with some aftermarkets goodies but after frogskinnin up those holes we definately saw a reduction of scattered belts that always will explode midstream up a fricken wall of snow and carnage of course! I uippose ultimately its all a bout fitting yer sled to your style. Comments please.
