I purchased one of these MotaReva kits it works very well and any errors made was with the operator, it took a little practice to get it right but once mastered I had a consistent result every time small price to pay for piece of mind I say

Subject: Re: [DucatiST] Re: ExactFit Timing belts
Ducati Specs as per 2009 service bulletin:
New Belts 110hz +/- 5hz
Used Belts 100-90hz +/- 5hz
This is for BOTH horiz and vert cylinders.
Anything else, is whatever you trust to perform on your machine. MotoReva has a unit to measure belt tension by frequency. LT Snyder sells them on his website. I personally use it on all of my personal bikes when I work at home. Belt tension is not just for belt life, it also makes sure cam timing is correct when the bike is hot. When the engine heats up the belts get tighter, as the head and cylinder grow in length, so cold belt tension is critical to proper engine performance.
My suggestion is we buy one and ship it around with the shim kits.
YMMV

I'd like your opinion on the adjustment of the timing belts using the allen wrench method. Here's what I've found:
I've adjusted the belts so they are about as tight as I can get them by pushing on the tensioning roller by hand and then tightening the securing screws. My bike is an ST2 so I'm using the suggested 4mm allen wrench for both belts. I can get the 4mm allen wrench to pass between the belt and the non-adjusting roller, the fit is tight and there's alot of resistance to passing it through, so it seems about right. However, I can also pass a 5mm allen through although it's tough to get it through, but I can with one hand. I can also get a 6mm allen through if I use both hands with alot of strain. As a double check, I can also twist the belt about 45 degrees. Does this sound like the proper adjustment?
Thanks

Ive had exactfit the belts on for two years now and they seem fine although I have only covered 6000kms. I have always used the 5mm method. tried the mic/Hz method and didn't like the inconsistency of my readings so ditched that method for what I knew worked.
FWIW After 5000kms on new OEM belts I couldn't believe how much they had loosened up. Sounds like a similar amount to what you have found with the exactfit.
