Mine did exactly the same. 2003 model with only 7k on the clock.
Im sure it didnt when i bought it but sounded like this after I stripped the top end but i hear the engine is a chittery old thing anyway.. As it comes from the top right, it maybe the Rev counter drive which is built onto the camshaft.
Iv just done my clearances again as they seem to have already closed up in only 3 weeks, I set them to 0.1 Intake and 1.5 Ex which has removed the tappet noise.
I also removed my MIG exhaust can and went back to the original. I didnt rejet so i think this was leading the bike to be running to lean and causing engine noise.
Illl be selling it and getting a full load legal Lazer Exhaust.
BTW, pushing out your camchain pin is not good fullstop..you will wear the guides out and stretch the chain !! If you think its the tensioner then change the spring for a proper Yam one. The spring tension is critical and obviously wears !
