Does the noise come from the lower right side of the engine (clutch cover) & sound like a chain sliding on metal? I just adjusted the valves on my 400 & now I have that noise. From what I read on TT it is most likely the counterbalancer gear working itself loose. I didn't notice the noise before the valve adjustment but I can't think of any reason why adjusting the valves would have caused or accelerated the CB gear from coming loose.

I don't think this could be it. It sounds like tac, tac,tac,tac at the same time as the revolutions of the engine. That is what makes me beleive it could be the valve clearance after I changed the cam timing. I think I will go to the dealer and ask them to hear it, and probably ask for a price quote. What kind of job is it to adjust and measure precisely and fix the valve clearance, if it is easy I will do it myself since I have been there when I changed the timing.
Thank you for any other advise!

I think I installed the cam chain tensioner, but I don't recall a 'release'. I wound the spring with a screw driver, installed the thing in the 'up' position and could see the chain tighten up as the tensioner released.
Did I miss something?

I've always wondered about rotating the cam one tooth and why it did not throw off the valve clearance measurments. I have never researched it but are the YZ and WR clearance measurements different? And if so, shouldn't we be using the YZ measurements. If that is the case (which it seems to not be) would the make more engine noise.
I've really never worried about it as the bike runs and I'm not one for tearing into engines. The less I have to the better.
