Have acquired a noticeable tapping sound on the honda cbf125 engine. Makes the loud tapping sound when idle and increases with revs. Im wondering if this could be something to do with the cam chain tensioner (bike is at 33k miles) or if it could be the bearing roller on crankshaft?
I have a haynes manual for the bike and this would be my first attempt ever at looking inside an engine.
Any help would be greatly appreciated and was wondering what are the simple things i should check first before getting the engine out.
Thanks, Phil.
