I have the top end and jug off the bike, is there anything I should do with the crank as far as maintanence is concerned. I've heard of the crank bearings drying out, is there something I can do to remedy this? The bike won't be back together for probably a couple of weeks. The last thing I want to do is redo the topend and have the bearings go. The bike is stored outside, I could however bring it inside if that would help...
