1. Place the bike on a stand or lift.
2. Remove the three allen bolts holding the instrument panel to the tank.
3. While leaving the two wire harnesses connected, hang the instrument panel over the handlebars 
    making sure to use a towel to protect from scratching.
4. Turn the fuel valve off.  Disconnect the fuel hose aft of the valve while holding a rag in one had to 
    prevent residual fuel from dripping on the bike.
5. At the rear of the tank, disconnect the small green electrical connector.
6. Disconnect the air breather tube at the front of the tank.
7. Remove the long through bolt at the rear of the tank and set aside.
8. Using both hands slowly pull tank towards the rear of the bike to dislodging from the 
    rubber forward mounts.
9. Set tank out of the way.
 

Removing the Timing Left side Cover

1. Using a phillips screw driver, remove the two screws holding the kick stand kill switch and let hang.
2. Using an allen driver, remove the six bolts holding the gray (mine is chrome now <G>) cover. 
    (note that two of the bolts are two different lengths.  Make sure you remember where 
     they came from.)
3. Remove the two black plastic plugs with a large slotted screwdriver.  Be careful not to lose 
    the "O" rings.  Set aside. You will come back to this area of the bike when you're ready to 
    adjust the valves for clearance to close up.
 

Removing the Valve Covers, Valve Cover Extensions, 
and Loosening the Rocker Arm Bases on Both Cylinders

1. Disconnect the two black rubber hoses going to the rear valve cover. 
    (#1 cylinder by the way).  Stow out of the way. 
2. Disconnect the four spark plug wires and stow them out of the way. 
3. Loosen, (do not remove) one spark plug in each cylinder. 
    (Very lose, but not out. This will allow you to turn the engine over when the time comes.)
4. Remove all 12 hex bolt holding the chrome valve cover on.  (Both cylinders.) 
    Don't worry about that there are several different lengths.   In Tidy’s maintenance hints, 
                                          
    they have a color picture telling you exactly where they go back.
5. Now carefully slide out the chrome covers from both the front (#2) and the rear (#1cylinder) 
    You must lift up a little to get them out.
6. There are two chrome pins (keying devices if you will) that either are stuck to the covers 
    you've taken off, or they are still in the next chrome piece (valve cover spacer). 
    Find them, remove them and set aside.  (This is why you left the spark plugs just lose and 
    not out.  Can you imagine if you dropped them in the cylinder holes!)
7. Next, remove the metal like cover gasket from each cylinder making sure not to bend, 
    staple or mutilate.  These will be reused.  Set aside.
8. Next, remove the 6 bolts holding the valve cover spacer on.  Again, under them are two 
    more of these chrome key way pins and gaskets.  Do as you did in the previous steps. 
    Keep the bolts, pins, and gaskets segregated for piece of mine.
9. Now comes the fun!  Loosen the bolts holding the rocker arm bases for both cylinders. 
    It is not necessary to take the bolts out.  Just leave them loose in the holes. 
10. Locate the two push rods for each cylinder exposed at the r/h end of the valve assy and 
      lay a rag between the rods.  This way you will know which valve arm assembly they return to
      when it's put back together.  (All of this will save you the time of taking the entire 
      push rod assembly apart, the sleeves, and the lifters.)
11. Now, very slowly lift up on the push rod end of the rocker arm base until the push rods 
      come out from under the rocker arms.  This will free up the lifters down below for replacing
      the cams without taking the push rod covers, push rods, and lifters out.  (Worked for me!)
 

Removing Cam Cover and Cams and Installing Replacements!

1.  Remove the two hex bolts holding the decompression cover on. (Have chromed if you like.) 
2.  Remove the decompression solenoid and let hang.
3.  Remove the hex head bolts holding the cam sprocket cover on.  Place aside. 
     (Will require a new gasket upon re-assembly)
4.  Inside you will see the smaller Drive Gear, which is on the crankshaft), the larger 
     Driven Gear, (which is on the rear cylinder cam), a round disc plate with two allen screws, 
     (which hold the front cam in place), and two rod like devices sticking out the end of the two 
     cams.  Remove the rods and place aside.  They are different lengths, so just remember
     the long one goes in the rear cylinder cam, and the short one in the front cylinder cam. 
     (I’ll remind you later too)
5.  Look for the indent marks (small dimple) on both gears.  If they are not pointing at each 
     other (aligned opposite each other) you will have to turn the engine until they are. 
     THIS IS CRITICAL TO PUTTING THE BIKE BACK TOGETHER PROPERLY
6.  Place a small rag down at the bottom of the cam cover opening where you see the holes that 
     lead back to the crankcase. 
7.  Now that the Drive Gear and the Driven Gear are exposed “we” will be removing both. 
     The Drive Gear (smaller one) is held on the crank with a hex bolt.  In order to remove it, 
     place a copper washer, or some other soft material wedged in the gears between this gear
     and the Driven Gear so it will not turn as you loosen it.  Place the material in between the 
     teeth on the right hand side as the gear will want to turn counter clockwise to be removed. 
     After you remove this bolt and washer set aside.  DON'T REMOVE THE GEAR YET!
8.  Next, do the same with the nut that holds the Driven Gear on the rear camshaft. 
     This time place the copper washer in the gears on the left side.  Loosen the nut and 
     remove along with the washer and set aside.  (MAKE SURE THE COPPER WASHERS 
     OR THE SOFT MATERIAL YOU USED HAS BEEN REMOVED.)
9.  Slide both the Drive Gear and the Driven gear off their respective shafts. 
     (A slight nudging with a screw driver from behind works fine) They both have straight 
     keys that will come off at the same time.  Make very sure not to lose them or allow to 
     them to get down under your rag that's blocking the oil holes to the crank case. 
     Set gears aside with straight keys.
10. Loosen the two hex bolts that are in the round plate at the end of the front cylinder cam 
      (camshaft end cover bolts) Remove the bolts and the plate and set aside. 
      (Make sure when we get to reinstalling this plate you use blue loctite.)
11. Last item to remove before we remove the camshaft cover is the oil deliver tube. 
      At the 11 o'clock position from where you removed the round front cam cover is one
      more hex bolt that holds the oil deliver tube.  Remove it and slide out the oil deliver tube. 
      Note that there is an O ring at the far end.  Make sure when you reinstall it's in place.
12. Loosen and remove the last six (6) hex bolts holding the camshaft cover in place. 
      Set the hardware aside.
13. While holding in on the two camshaft exposed ends (your trying to keep them from 
      coming out with the cam cover), carefully pull out (resistance of the cam cover gasket) 
      on the cam cover.  It will break lose.  You are trying to make sure the cams stay in under 
      the lifters so the lifters don't fall down out of the push rod assemblies. 
      (The book has you do this completely different, but my way is a whole lot shorter and 
      as far as I can tell had no ill effect.)  Assembly too!

New Cam Installation

1. Take the new cams and lube them up with cam grease (molybdenum). 
     I bought two very small tubes of this stuff at the local automotive store. 
     (One tube is ten times too much <G>)  Lube not only the lobes, but the cam journals.
2.  Rear cam replacement first:  While holding the old cam in place, slide a screw driver 
     under the two lifters that ride on this cam and hold them back up inside the push rod 
     assembly (you only need to make enough room to slide out this cam and reinsert the new one.)
     Slowly pull out the old cam and slide in the new one.  Gently push it into the journal house 
     at the far end.  Let the two lifters come back down and ride on the new cam. 
     Check and you will see that they are sitting on the lobes. 
3.  Repeat step 2 for the front cam replacement.
4.  Take the cam lube and apply the grease to the holes in the cam cover. 
     Don't get carried away and plug up the slots and hole where oil is suppose to flow to
     the journals.  Just light lube here folks.
5.  Take the new gasket for the camshaft cover and spray with gasket seal on both sides. 
     This not only insures no leaks, but helps hold the gasket in place when you reassemble. 
     (By the way, there are key way pins just like the ones on the valve covers so the covers 
     go on nice a straight.)
6.  Place the new gasket on the engine block.  Make sure holes all line up.
7.  Carefully take the cam cover and install over the two cam shaft journals and push the 
     cover up securely to the gasket.  Re install the 5 hex head bolts.  Re-torque to proper value. 
     ( 5.1 ft. lbs.)
8.  Using some light grease re-lube the O ring on the oil deliver tube and reinsert into the
     cam cover.  Install the bolt that held it in place. Torque to 5.1 ft. lbs.
9.  Install the front cam round cover by installing the two hex bolts.  Use some blue loctite to 
     secure these screws and torque to 7.2 ft. lbs.
10. Install the Cam Drive gear over the crank end.  Place the straight key in the slot and 
      align the key way.  Replace the washer and bolt. (we'll retorque shortly.)
11. The tricky part.  You will see that the Driven Gear has two gears that are not quite aligned. 
      Using an awl, or a round bladed screw driver in one of the holes in the gear assembly, 
      align the gears so they will both be on the same cog as you install the Driven Gear on 
      the shaft of the rear camshaft and meshing with the Drive Gear.  (The book in chapter 5 
      explains this well.) 
12. Install the straight key and install the washer and hex nut.
13. Reversing the procedure that allowed you to break the nut and bolt lose when removing, 
      use the copper washer or soft material and retorque them.  The nut is torqued to 37 ft. lbs. 
      And the bolt is torqued to 22 ft. lbs.
14. Re install the two decompression pins.  The short one goes in the front camshaft end 
      (through the round end plate), and the long one in the rear camshaft end.
15. Carefully remove the rag you had covering the holes in the bottom. 
      Make sure no foreign (or domestic) material  drops out when the rag is removed.
