Has the sound changed on yours since you first got it? Or is it the same as it's always been?

he advised me annual change, so i believe after two years I should replace it
(the book also states for regular chain check for tight spots...) and your bike has quite a lot of miles, hope you change oil regularly
If you ride a lot of street, I would advise you to suit the gearing to the road (15 front, 46-48 rear) to avoid stressing the engine with unnecessary constant high RPM's
taking out the chain tensioner is no big deal, but if you have no experience in such repair, i would advise you, to take it to the mech and let his ear decide the cause
chain is not expensive, dont know for the tensioner, and theres not much work to replace those two
still i believe theres nothing wrong with the bike (yamaha engine is quite noisy, but so are al modern 4T's), just reflecting noise from the surfaces but you can never be sure, untill you see/hear the problem

However, I think 5 valve is right, you probably want to check it out, or have the shop check the timing chain and tensioner. You know, the technology in these bikes isn't really engineered to put long sustained, higher RPM mileage on these powerplants. It seems to me that a TTR engine would be much better suited for that kind of use. I know many of you guys Dual Sport the WR's but if you think about it they are made for 50 or 100 mile rides, and then get a bunch of maintenance. Read the manual and see what the recommended valve clearance check is. I think it's "Every 3 races", which equates to how many days going to work? Probably not many.
