Hey guys. I posted over on SVR a couple of days ago, but haven't received any input yet. Perhaps one of the gurus here can help.
2005 SV650 with 32,500ish miles.
I've noticed an intermittent clatter coming from the motor at 2500rpm. It seems to happen more when the bike is hot, but not every time. I do have it isolated to the motor, as opposed to the drivetrain, by pulling the clutch lever and revving to 2500 while stopped (I can cause clatter that way sometimes), and by pulling the clutch and letting the rpms change while coasting (clatter stops). It does not clatter at idle, nor does it clatter over 3000 rpm (or maybe I can't hear it any more).
I notice it most when coasting/decelerating through 2500 rpm slowly, it's not like I lug it around at 2500 rpm all the time.
My oil level is acceptable, with just 2600 miles since the last change. I am planning to change in 400 more miles, as usual.
I suspect a lazy timing chain tensioner. Just looking for confirmation/consensus from the community.
I took a peek in my service manual, but I can't tell if the tensioners are oil pressurized or if they're only on spring tension. Thanks in advance.
