Your belt usually stretches in the first 20 or so miles. You can then adjust to proper belt deflection. If clutches are properly aligned it should be good for 1000's of miles. However I check mine frequently as I am a bit of a tinkerer. There are simple instructions in your operators manual on how to perform the task. If you are not comfortable with doing it yourself your dealer can do it in less than 5 minutes.Just wondering, how often do you check your belt deflection? Do you do it yourself or do you take it to the dealer for inspection and possible adjustment each and every time?
