Questioni have a 1968 CL77 that i am trying to get running i have made great progress at getting things running after i aquired this bike that has not run for about 15 years or so. Any way i was cleaning the points and parts behind them. I removed them from there backing plate. In my over site I did not mark where they were set to before removal. I took of the stator cover and can easily read the makings on it for the settings, butthe problem is that i don't know what the mean or how to properly set the timing. I appericate any help you can provide.
Thank You
Adam
AnswerAdam, I copied this from the honda305.com site under the FAQ section. It was written by Ed Moore, a noted restorer in Texas.
Tools Required:
.014 feeler gauge (to set right side points)
Spark plug wrench
Large vise grip pliers (to put on the bolt head at the rotor so engine crank will be able to be moved back and forth) The crank will go "OVER CENTER" if you use wrenches!!!!!!!!
Phillips screwdriver (plate and cover screws)
Flat head screwdriver (points screws)
12 volt light with one foot long wires and alligator clips on the end (to see exactly when the points open) NOT A TIMING LIGHT!!!!!!!
NOW!!!!!!!!!!!!
Remove point and rotor covers.
Clean both sets of points. MAKE SURE THEY ARE CLEAN!!!!!!!!!!!!
Install new spark plugs.
Turn carb slide adjuster screws out enough for the slides to bottom out on the carb.
Adjust air screws to 1 1/8 open from bottom. Will readjust when engine is hot!!!!!
CB72/77 - Remove the air intake tubes and put middle finger in left carb and thumb in the right carb.
CL72/77 - Remove the tool can and put middle finger in left carb and thumb in the right carb.
Move throttle handle and if both slides don't move at "exactly the same time" adjust the screws on the top of the carbs so they do. Be sure to have at least 1/8 inch slack in the throttle handle.
Set "R" points to .014" when the points rubbing block is on the highest location of the points cam. Tighten the screws. (you are through with them!
Put alligator clips on the "R" points and engine case. Put bulb behind the left carb. BRIGHT YOU KNOW!
Turn key to "ON".
Turn crank with Vise Grips so "F" is in line with pointer at rotor area. (The mark on point cam should be down. If it is up. Crank engine 360 degrees.)
Loosen points plate.
Hold crank somehow at "F" to marker and adjust PLATE so light JUST comes on at "F".
Tighten plate. Check opening now by moving pliers forward then back. If light comes on other than at "F". Adjust plate until it does when the plate is tightened. May require a couple of adjustments. You are through with the plate.
Move alligator clip to "L" points.
Move crank 180 degrees.
Loosen "L" points and adjust until light just comes on at "LF".
Tighten and check by moving crank back and forth. Readjust if needed.
When both points are adjusted:
Turn off key switch.
Remove tools and turn slide screws in a couple of turns.
Choke lever to 3/4 closed.
Turn gas lever on. WAIT!
Engine in "NEUTRAL"
Key "ON".
CL72/77 - Kick start the motor.
Engine will fire and run somewhat.
Run until you can OPEN the choke all the way.
Adjust slide screws to even cylinder speeds.
When engine is hot adjust slide screws so engine idles at around 800 RPM.
Adjust air screws. 1 1/4 turn max here. Usually open a small amount to smooth idle. Never more than 1 1/2 turns open from bottom total. May need to open slide screws after this to lower RPM.
Install the air tubes and go ride.
Final note:
If the points are new. You will find they WEAR IN to the point cam and will need to be adjusted a couple of times until they are WORN IN.
Seems like a lot but not really because it works.
