hello all, i purchased an r6 99" a few months ago now, and i think its time for service. the last owner couldnt remember when he last serviced it, and sometimes wehn i ride i can hear backfire :/ bike has done about 62,000kms now. anyway question is 1. what type of oil should i use for the bike? 2. do i top it up or flush the oil out? - if i flush, how much oil needs to be put in? 3. brake fluid is dot4 ? (correct me if im wrong) 4. what spark plugs to use (model) 5. what oil filter should i use? 6. air filter - do i dab new oil on it (moist it) or leave it dry? thanks for any help. would apperciate if you dont give me any links to look up, im on a work computer and a few sites have been blocked off.
