As you've got the 800 motor, Darren's pins are the ones for your model; the larger pins are for the S2R 1000 and later models.

In case you're wondering where the pins go, they are shown in this service manual extract.



As has been mentioned previously, the pins aren't essential - if you do without them, just make sure you mark up the cam pulleys clearly and rotate the vertical cylinder to TDC power when checking that belt's tension.



Utopia, you're correct in assuming that the belt frequency should be checked at specific points. Those "plucking points" are also shown on this page.

Thanks, I'm glad to have confused things by clarifying the error! If you want to use drills or knitting needles or whatever you have to hand that's fine if it works for you. What if you want to pull the head off and keep the cams locked? For a couple of quid those factory style tools are suprisingly for a change pretty good value imho. You can make do, but the proper tools make the job much easier and have more uses than just a belt change.
