Amigos! I replalced one of my belt tensioner pulleys recently, because it was dying. The other three were ok feeling, and haven't caused a problem yet. I was curious after my ride today, and I hit the bearings with an IR thermometer. The new one was 120 f while the old ones were 199 f. I suspect whatever lube they have left in them is old and degraded. Theyll feel ok, but after 10 years of service i think I've gotten my money's worth. I found these in another thread, but I'm not 100% that they will fit my 08 s2r 1000.
The parts

The other thread

The price seems very good, and I would sleep/ride more peacefully with a new set of bearings.
Those look correct, but no FHE.
I like the IR thermometer check, that's interesting.
Thanks Speeddog,
Looking through some parts fiche's, I am only seeing 2 part numbers for the adjustable tensioner:
451.2.017.1A This one (from the pics in the fiche) has the 2 replaceable bearings with the circlip
451.2.020.1A This one (from the pics in the fiche) has the 1 piece construction
It looks like the S2R 1000 switched from 451.2.017.1A to 451.2.020.1A with the 2007 model. Are these the only 2 configurations in the 06 - 08 s2r (or DS1000) range?, If so, I think I'll take a gamble and be the guinea pig for these parts.

(Oddly the fiche's for '07/'08 call for 451.2.020.1A but show the circlip configureation in the picture. Im guessing they updated the part number, but not the diagram.)

(The '09/'10 SC 1000 shows the 1 piece construction with the same 451.2.020.1A part number. I'm guessing they finally decided to update the diagram!)
Diagrams are not super trustworthy.
I've only seen those two varieties of tensioner on post-Pantah engines.
I don't recall ever seen the 2-bearing style on a DS motor.
