Manual Cam Chain Tensioner - any noise?
I had my mechanic do a couple of reliability mods on my 40K miles '10 ST-R: installation of a UKRS oil cooler (planed and augmented with a passive PC CPU cooler too!) and a manual cam chain tensioner.
After taking it back however I noticed a noise coming from the motor, a rhythmic drone "har-har-har-har-har", not very audible but since I know the bike like my own body I immediately noticed it. It's nothing like the well-known rattle, I've known the rattle ever since I got the bike. This is less loud, and it's rhythmic - it follows the RPM of the motor and becomes stronger when I close the throttle, until the RPMs drop and it becomes more silent again.
Not thinking it might be due to the oil cooler (no moving parts) my thoughts are it's because of the manual cct. I looked through 27 pages of the relevant thread, and I found a single guy noticing a noise and asking a question but he never received any answer.
Now - any of you guys with manual CCTs - did you have any such rhythmic noise after this installation? If yes might it be because of over-tightening?
Thanks in advance for any replies.
