First, let me apologize for pushing back this subject. I know it has been beaten to death, so much indeed I've been quite confused by the 345 posts about what's where and the 173 ways of getting rid of these 'unnecessary' stuff !!! I'm the very happy owner of a new European KTM950 (850 km so far). I've just received the Sommer Airbox, which I plan to ask my dealer to put on the bike at the 1,000 km service. It's running PERFECTLY, so I want to keep cobbling to a minimum! Is there anything like EPC I should get rid of on this 2004 Euro bike ? And what's the easiest way ? (I've switched to the KTM aluminium silencers already, so I know I can get rid of the SAS, but do not really see the point).
