As you can see the entire top of the airbox has been cutout (not by me). The question is weather its safe enought from scrap, dirt and water? I dont mind cleaning it often. Or should I do something about it? It will be rejetted since I have installed a few bits and pieces during the winter.

I guess the DT200 or 230 would fit as well

As said, I just run a pod filter as it means you don't butcher an OEM part.

]]>https://dt125r.co.uk/post/13600https://dt125r.co.uk/post/13600Thu, 22 Feb 2018 20:07:18 GMTPerfectly fine. Sir boxes on these are really restrictive.
