New cam chain tensioner, still clatters
Posted: Wed Nov 25, 2009 3:50 pm
I did the swap, from what I read I've got the 2nd upgrade version with parts ending in
656 922 and 688 629, and don't have the little short internal dark colored piston or whatever
it was that is pictured in the "original upgrade".
I even took it apart and checked to make sure.
Trouble is, it didn't quiet the clatter down very much.
And, yes, the rockers and valve lash are set to the closer end of the tolerance range,
but I think about .003 above the tight end if I remember right. If that number is wrong,
at least it's closer to the tight end of the range than the loose end, but not at the
minimum clearance.
It clatters all the time at idle and just above, sound is like some very loose lifters.
Clatter goes away about 2k rpm. I'm half deaf and it still sounds alarmingly loud to me.
Haven't checked with my stethescope, but sounds a little louder on the left side than the right.
Warm or cold, doesn't matter. Engine oil weight doesn't matter.
Any ideas? People regularly post that they did the tensioner swap and the engine
is then virtually clatter free. Has me worried. Going to cut my filter apart and see
if I have any flakes. And see if I can pinpoint the clatter with my stethescope.
Got the bike July of 08 with 25k miles, it's an 04 model.
I don't remember it clattering that much before I set the rockers and valves,
other than during startup before I did the tensioner swap.
They were within tolerance but were uneven and more toward the loose end.
Thanks!
