1000DS, Belt offset from roller, question.

[colin748916]

I have just changed the toothed belts on my 2006 S2R1000 and when rotating the belts keep wandering outwards and finally line up with their outer edges 1-2mm off the edges of the cam rollers. This can't be ok, can it? The drive rollers are correctly mounted but not yet fully torqued, what can be wrong?

Try torquing the pulley nuts down all the way, see if that does it.

And- how did you set tension?

how did you set tension?

Both belts are still a bit slack as I copied the tension of the old belts by meassure. One was very tight, the other fit the 5mm Allen. I plan to trailer the short way to my dealer and have them set the correct tension. But first I would like to see the belts track correctly, I will set the tension to the specified 140Hz and see if that helps.

That spec might be high.  There are un-official opinions that belts that tight also cause pulley bearing failures.  Check with your dealer and see what they use.
