Forgive the noob (to KTM) question. I've recently bought a slightly used 2012 ADV (standard). I've already added the Weld86 skid plate and CJDesigns side stand relocation bracket, based on advice I've read on the forum. Now I'm thinking about adding Wings exhaust, and maybe SAS blanking plates, canisterectomy, etc. How much can I do before I invalidate the warranty? Given that there is a lot of warranty left on my bike, should these mods wait?
