Valves on my bike are off

You will have to buy some tappet shims from the dealer to do it, and you will need some tools:
Adjusting the valves is time consuming and sometimes frustrating because the service manual does a poor job of explaining the necessary steps (some omissions and editorial shortcomings in the manual). Set aside several hours because it involves removing the seat, tank, front body work, some items under the tank, spark plugs, valve cover, and signal generator cover. You must also adjust the valves when the engine is stone cold (at least 12 hrs. not run). There are some tricks to adjusting forked rockers and some omissions in the techniques in the shop manual. I highly recommend buying the $9 U.S. tool #09917-14920 valve adjuster driver. It's a small nut driver looking thing that mates with the tiny square head of the screw adjusters. It's extremely useful in holding the screw while you tighten the lock nut. If you don't have it, you'll have a hard time maintaining the proper lash as you tighten. You can also purchase these tools at good performance shops.
• Remove the seat
• Removing the tank is covered elsewhere on this page. Click on the "Back" arrow in your browser's tool bar to get back here.
• Remove the fairing by removing the four windscreen fasteners and lifting off the screen. Remove the four screws that secure the black inner panel and remove the panel. (Now may be a good time to cover all points of contact between the rest of the fairing/screen assembly and this cover with thin foam tape -- it will eliminate that buzzing we all have at 2k rpm.) Disconnect the front turn signals' harness connections inside the fairing. Remove the turn signals by removing the securing nut inside the fairing and pulling the signals out carefully. Remove the five fasteners on one side of the fairing (Three near the headlight, one that was behind the black panel and one at the lower rear corner of the fairing). Remove that side of the fairing and repeat for the other side.
• Remove the spark plugs with the wrench provided in the tool kit. Place clean shop rags in the spark plug tunnels to guard against dropping anything into the combustion chambers.
• Remove some items under the tank (not covered in the manual). Remove the braces on the frame that locate the left and right side fairing pieces. Remove the ignition coils (note the position, routing and connections of the wires). Disconnect breather hose from valve cover breather. Remove valve cover breather by removing its four bolts. The manual specifically states that this last step is unnecessary, but you'll bugger-up the valve cover and may not be able to get it out without removing the breather.
• Remove the valve cover by removing the 14 bolts holding it in place. Don't lose the small metal gaskets under each of these bolts. Don't forget the two near the timing chain bulge and the four (union bolts) near the spark plug towers. Pull it carefully out the right side of the bike. Look carefully under the cover as you guide the plug towers over the timing chain; you can easily lose one of the small gaskets at the bases of these towers. Remove and clean the valve cover gasket (strip off any silicone sealer) and the mating surfaces on the head and valve cover. You can reuse the head cover gasket as long as it's pliable.
• Remove the signal generator cover by removing the five bolts holding it in place. If you're careful in peeling the gasket off, you'll be able to reuse it (once) with a coating of Suzuki Bond gasket sealer.
• Note the two notches on the right ends of the cam shafts. These will be parallel with the head surface when the crank is rotated to the two positions where you adjust valves.
• Rotate the crank forward (clockwise) with a breaker bar or large wrench (19mm) on the signal generator nut (right end of crank under just-removed cover) until these marks on the cams line up with the head surface (horizontal) on the outside of each cam (the marks will be "pointing" away from each other).
