Hi Guest,
you might follow this guide (and just cancel the not required steps).
I mean you’ll need the steps:
1.
3. (removing not necessary, loosening the kick stand bolt is enough)
5. - 10.
13.
14.
20. - 24.
Please let me know if there are further questions 
Edit:
I’ve mentioned the following already in the Schlumpf guide but due to it’s importance I’ll repeat here:
Please check the condition of part 338 (magnet spacer)!
If the flange is bent (caused by too much tension on the wheel bolt 379) the part must be replaced.
A damaged magnet spacer may cause belt twisting.
Belt twisted twice
