Did you try this one? http://www.ukmonster.co.uk/monster/s...ad.php?t=56189

If there's nothing suitable, there's always the tried and tested allen key method.

For what it's worth, I fitted my belts using that method before taking it to Moto Rapido to check the valves. Because the valves needed adjustment, the belts had to come off again anyway and Moto Rapido refitted them, tensioned to 140 Hz. Out if interest, I checked the tension with allen keys and found that a 4mm key was a tight fit on both belts as against the 6mm and 5mm recommended by the allen key method. (The Evo workshop manual gives the same tension for both cylinders).

It seems to me that an exact tension is not that vital since the operating window is pretty wide - 140 Hz when new, 100 Hz for used and no adjustment needed until a used belt drops below 70 Hz.
