    Query Approved

    Just ride normally and try not to rev the engine too much. Stick to 3-4k RPM till you complete at least 500km after the O/H and you should be good to go.
    Advice is a form of nostalgia.
    Dispensing it is a way of fishing the past from the disposal, wiping it off, painting over the ugly parts and recycling it for more than it's worth.

      Engine overhaul care



      Valve Timing
      Valves carry out critical tasks during these four strokes: they open the intake valves, letting a fresh gas/air charge into the combustion chamber, and then close; they also open the exhaust port, releasing the spent exhaust gasses, before closing and resealing the combustion chamber. And they do each of these things at precisely the right time, but only if the valves are adjusted correctly.

      The Connection
      Pistons and the timing of the valves opening and closing is connected; the two move in concert. The piston is connected to the connecting rod, which is connected to the crankshaft, which connects to the camshaft by way of the timing chain. The contour or lobes of the camshaft mechanically time the opening and closing of the valves with great precision.

      Valve Lash and Adjustment
      Valve lash is measure with a thin, flat feeler gauge. Each engine has specifications for its maximum range of valve lash. The engine must by turned to a precise position in its cycle, then the feeler is inserted between the valve and the lifter. If the lash or gap is within factory specs (or the specs designated by any aftermarket performance modifications), no adjustment is necessary. Otherwise, the valve needs to be adjusted, bringing the lash into factory-specified range, which is critical for the engine's timing, performance and preservation.

        Installing The New Chain
        7
        Drop the new chain through the cylinder head. Wrap it around the upper timing cog, and loosen the timing chain tensioner.

        8
        Wrap the chain around the lower timing cog. Replace the valve timing rod and be sure all bolts are tight.

        9
        Tighten the timing chain tensioner until there is no apparent slack in the timing chain. Do not over-tighten the tensioner or your motorcycle will run poorly.

        10
        Replace the side cover and valve cover.

        11
        Replace any parts taken off of the bike to perform the chain swap, start the bike and listen to the silence of a new timing chain.

          Clutch Plate
          Remove the clutch pressure plate bolts counterclockwise in a crisscross pattern using a socket and ratchet. The bolts are pre-loaded by the clutch springs behind the plate; fully removing the bolts one at a time is not advisable. Remove the pressure plate bolts and set them aside. Pull the circular lifter off the end of the operating rod in the center of the clutch components. Set the lifter aside.

          4
          Pull the factory pressure plate off and discard it. Pull the factory clutch springs off the spring posts inside the clutch housing by hand and discard them. Pull the lifter rod out of the center of the clutch housing by hand and set it aside.

          5
          Pull the individual factory clutch plates and metal discs out of the clutch housing by hand. Discard them. Remove the lifter rod spring from the circular metal cup at the back of the clutch housing by hand and discard it.

          Installation
          6
          Clean the clutch housing thoroughly using a rag with a modest amount of transmission oil. Turn the rag frequently to pick up and remove all clutch plate debris and dirt. Inspect the housing and make sure it is free of debris or dirt. Clean it again, if necessary.

          7
          Push the new lifter spring into the circular metal cup in the center of the clutch housing. Coat the saved lifter rod with lithium grease. Push the lifter rod into the center of the lifter spring and fully into the circular metal cup.

          8
          Coat each side of the new clutch plates with transmission oil. Install a new metal clutch disc against the back of the clutch housing by hand. Install a new clutch plate against the metal disc by hand. Install the remaining clutch discs and clutch plates alternately by hand until all are in place in the clutch housing.

          9
          Push the individual racing clutch springs onto the spring posts at the back of the clutch housing. Put the saved lifter on the end of the lifting rod. Position the new racing pressure plate against the clutch springs and align the boltholes in the new plate with the openings in each clutch spring.

          Insert the saved clutch plate bolts into the pressure plate holes and thread them clockwise by hand. Tighten the bolts in a crisscross pattern using a torque wrench. Typical torque is approximately 7 ft. lbs. for each bolt.

          10
          Align the bolt holes in the saved clutch cover with the holes on the face of the clutch housing. Thread the saved cover bolts clockwise into the holes by hand. Tighten the clutch cover bolts clockwise with the socket and ratchet.

          Reattach the rear brake pedal, if you removed it. Thread the saved drain plug clockwise into the bottom of the crankcase and tighten it clockwise with the socket and ratchet. Fill the engine crankcase with fresh oil.

            though you have some valid points there, I feel these to be OT.
