That's about right, but be aware that you are better off having it a touch on the loose side than too tight. There are endless topics about factory spec's being too tight.......that's how I run mine anyways.

3.0 - 4.5 mm is just too tight. I had severe whining at 5 mm. At 10 mm it is doing just fine. A number of owners have reported front pulley bearing damaged by running at less that 5 mm. Others have had swing arm or rear wheel bearings damaged running that tight.

+1... OEM spec is well documented as too tight. It cost my bike two belts and a set of pulleys before it had 23k km's on the clock. I run the new (third) belt at 10mm / 10lb's, and have had no further problems.
