495 miles on the clock. picked up oil and filter on the way home. fired the bike up rode it around for about 15 minutes to get it warmed up. got home took it apart dropped the oil and filter, put a little oil in the filter, filled it up to spec. fired it up and no oil pressure after about 10 seconds and was starting to make a little noise so I shut it down. waited a few minutes and did it again, still no oil pressure. called the dealer and they gave me some crap about not letting them do it and then started asking questions. told them the same thing as above. told me to crank it up wile on the phone and to look at the oil level glass wile it was running. I did and he said it should drop when it started. it didn't then he told me to rev it just a bit, I revved it to about 2000 rpm and it started to make a lot of clunking noise and still no oil pressure. anyone else had this problem?
