could it be the cam chain tensioner by any chance? Even though you said on the left side, I think the cam chain tensioner is on the right side, have it checked and proceed!Noticed a loud ticking noise after doing an oil change on a 2013 Daytona 675. Could have been there before and I didnt notice but seems to be new. Sound is louded on the front left corner of the engine. What could it be?
