      Just put a new chain on my 95 Trotona. Replaced the original chain
      with a DID 530ZVM, 110 link, (http://www.didchain.com/) this is the
      chain that DID calls the Superbike chain, its the one they recommend
      for all 1200's. Cost $100 from Kiernan Racing Supplies
      (http://www.braincell.com/kiernan/). When I had the bike dynoed last
      fall the mechanic that operated the dyno looked at the graph of the
      power output and said it was time for a new chain. He pointed out
      that the line that graphed out was not smooth, it was the correct
      shape showing plenty of power but was full of little spikes and dips.
      The chain that came off was shot, stiff in many places. yes it was
      cleaned regularly with kerosene and kept lubricated with Chain Wax.
      Even though it was regularly cleaned it was caked with road grit and
      dried Chain Wax. Anyone have any experience with other chain lubes?
      NO WD40 WARS. I did not put on new sprockets but will do so next
      time. The rear sprocket was just beginning to show some wear. Can't
      see the front sprocket without removing the sprocket cover and that
      requires a new gasket, probably some seals and draining the engine
      oil, a poor design.

      Tools needed to do the job;
      DID KM 500 chain tool, pushes out old rivet, presses the side plate
      on and rivets (mushrooms over the pin ends) the new master link.
      27mm box end wrench to hold the chain tool
      19mm box end wrench or a 19mm socket to operate the chain tool
      Took about 30 minutes to do. Sure beats taking off the swing arm and
      putting an endless chain on. The newest edition of the factory shop
      manual dated 6/99 no longer has the warning that an endless chain
      must be used. It has instruction for fitting chains that use a rivet
      type of master kink and the front of the book lists a part number for
      the Triumph chain tool.

      The best part of the replacement is that the very mild vibration (a
      feeling of mechanical roughness - coarseness) at cruising speeds is
      gone. The bike feels smoother.
