So i have just been cleaning my 300's airfilter only to find just like the original filter it has what looks to be wear marks on it from rubbing against the rear wheel side of the airbox. The filter is stuffed so with 2 filters buggered i start looking why? And it seems the bottom of the airboot is peeling away from the airbox by about 10mm so im thinking this is why it is rubbing on the rear of the box? It also looks like inside the boot is delaminating! I think i have a faulty boot Anyone else had this? Not real happy when its my first day of 2 weeks off and wont be able to ride for the whole time aghhh.
