Putting a cam sensor on a single cylinder 4 stroke is unnecessary. It's extremely common to have a spark on BOTH upstrokes of the piston...one lights the mixture on the compression stroke, and the other just sparks on the exhaust stroke....the common description for this is "throw-away-spark".....so don't bother to look for a CMP on this engine

One thing I WOULD like to understand is how the second exhaust gas oxygen sensor is used on this engine....RamZ describes it in Honda literature....but I still don't understand the "whys".....and it better be a good explanation...oxygen sensors are not inexpensive....their value is in $$ not cents.
