Once upon a time I made a thread about using curved washers on the stock tensioner, and also one about using a skate wheel.

I also have run one bike with the stock tensioner without a bearing in it ( red tag kit) for a long time, no problems. I do run the chain a bit loose, always pull the clutch when I release the throttle, and make sure it is perfectly in line.
