Just make sure your chain has enough slack when the suspension is as loaded down as you ever run it. Setting up your rear shock preloads correctly, is my first step to prevent the chain from intermittently hitting the tension limit and of course riding comfort/handling. I believe all the specs for this is covered in the Big Blue Shop Manual. Set up your shocks under load first, I go by 25-30% collapse of the shock s travel/stroke while under load (fine tune with the provided spanner while riding if necessary) then do the final chain alignment/tension per spec. Anyway, that's how I do it. If you have installed a new rear sprocket and chain, visually check for even wear on the chain/sprocket contact area after a hundred or so miles, any misalignment will show in the wear pattern on the sprocket, adjust as necessary. I suggest you make minute adjustments to alleviate the problem here, if it's indeed an issue. One more thing, the Laser sprocket to sprocket alignment tool I bought, is one of the best motorcycle tools, I have ever invested in.
