2015 Evo 300 Air Box Cover Gap

Featured Replies

Hey all, Just bought my first trials bike. 2015 Evo 300 2T and Im beyond obsessed with trials. Now to the point. Day one, my friend looped the bike out and cracked the tail peice. Not sure how it is exactly supposed to sit but im guessing with the little flap tucked around the airbox. With it that way the air box cover does not seat all the way. The bolt is all the way down but there is still a gap. Any suggestions? Anyone have any photos of how it should look? Thanks

...and what have we learned? With the cover off there is a black plastic piece that holds the air filter in that has a screw in the front and a hole in the back for the cover screw. Both of these thread into brass inserts in the airbox. It's possible the rear insert got pulled out but unlikely.

Then take the cover off and shoot a picture under so we can have some idea of your problem. My guess is it will be pretty obvious. Yes the flap on the fender sits under the rear edge of the airbox.

I never learn...haha. The rear brass insert is raised out about 1mm. In my eyes, no enough to justify the gap shown in the first picture. Thanks for the input on the rear fender position. I will post up a picture later tonight with the air box cover off.
