Hello all, has anyone out there had any issues with keeping your chain slack adjustment? I mean, I will adjust the slack and after a very short time the chain seems to have lost the tension. I always torque the two tension bolts to what the book says, 48ft/lbs. I have never exceeded that torque tension, wonder if a few more pounds of pressure would do the trick? I think the other system with the pinch bolts is more reliable. Your thoughts...
