Hi All, I have adjusted my own belt and am happy with the result. I used this - to achieve 'somewhat accurate' measurements. This particular digital caliper can be purchased at Harbor Freight for $20 +/- and this - which I purchased from 'Motion Pro' for $28 +/- again to apply the proper pressure to the belt prior to taking a deflection measurement.
I then followed the directions in the manual (for the most part). 1) I applied the pressure to the belt with the above tool 2) I then checked belt deflection making marks on a carpenter's square with it standing vertical next to the belt. 3) I checked the distance (in milimeters) between the marks I make on the carpenter's square using my digital caliper 4) I then made my adjustments on the axle adjuster nuts. 5) I then rechecked my belt deflection. 6) I then used the digital caliper as a measurement tool to square up the axle (rather than using the factory marks on the swingarm) 7) I rechecked and adjusted the deflection and readjusted the axle for 'square'. 8) Chirp Gone! 9) Don't forget to retighten the axle nut! My 'Owners Manual' says the belt deflection should be 12mm. I purchased a 'Service Manual' and it says the deflection should be 20mm. I went to my Dealer's showroom and checked the 3 Visions they had on the floor (which may not have been serviced-out yet) and their belts seemed to be all of a consistent tension and 'loose' in my humble opinion so I'm not sure what the story is there. My belt is a skosh tighter than the recommended 20mm as it is at 19.57mm after I squared my axle the last time. I have only put 40 miles +/- on my bike since I adjusted the belt so the chirp could return, however it is nice and quiet currently. It is running on the right (outboard) side of the rear pulley...I'm not sure if that is good or bad. I do know QUIET is a good thing! I would be interested in the approach others have used to adjust their belts...How did you adjust yours? |
