All was fine until now. The belt has noticeable slack and the tensioner can be turned freely by hand.

Suggestions?

Fixed it.

After I rolled the motor i just put the tensioner back on.

I did not tension the belt by pulling on it as you tighten it up.

.......Must be the old age.......

Might be old age (the belt not mine Ha Ha), but after a spirited run last Sunday, the drive belt is decidedly slack. I can now move the center of the belt (exactly between the two pullies) through a one inch travel, where in the past I could barely get 1/2 inch movement.

Idler pulley looks and feels tight and the front & rear pullies are also tight. The belt seems to have stretched?

Oh! it's an XB12s, 2006 model with 18,600 miles on it (original belt).

Any thoughts?

Rage, there was a problem with some S1s in that the splines on the front sprocket would shear leaving nothing for the countershaft to bite into. The teeth on the drive sprocket that contact the belt would be OK though.

Is this what happened to yours?
