You need an outerwear pull start and air filter cover for sure.
There are also vent holes in the back of the engine that suck in a lot of poop. I have a mod you can do that will take care of this but it involves removing the engine.
Use a good silicon and glue some fiberglass screen over the holes.
After that, cut the extra air filter cover that came with the Baja and Zip-tie it on. Nothing gets through and it still cools just fine.
