Just put new tires on so while I had the rear tire off I lubed the spline with Moly. Putting it back together the specs call to torque the bolts to 17.5 ft/lbs. I do not have a torque wrence that goes that low. How important is this torque spec? Currently I just tightened them by feel, little more that snug. BTW when I took the final drive off the spline was greased well. I was very happy to see this as I just bought the bike this winter. I did not know about the spline troubles until after I bought the bike and found this forum.
