Yesterday I went on a 500 mile trip with the R3. Boy, does my ass hurt , I need to start looking into a different seat with a backrest on it. Anyway, while I was out and about I noticed that oil spray was covering my left exhaust heat shield . Upon further inspection the oil appears to be originating from somewhere under or behind the oil tank. I don't think it is coming from the cylinder head but maybe from the oil tank where it connects to the engine case. Anyone else have this problem and if so how hard is it to remove the oil tank and replace the o-rings? I don't plan on taking it back to the dealer unless it is something major and even then I'm not sure I would. I don't like letting anyone else touching her as it always seems they cause more damage than they fix. Any advice would be appreciated.
