Hi David;
Please join in...
The difference in the cam is lobe duration. To regrind the cam most just take some off the bottom end of the lobe resulting in a too low adjustment for the rocker arms as they use the eccentric at each end of the rocker arm shaft to take up the adjustment needed to open the valve properly at between .003 to .004 gap on the back side of each lobe and the rocker arm. Original cam/rocker/valve assembly didn’t require a lash cap as there was enough meat in the assembly to give long life to the adjustment.
However when you take some of that away, it has to be put back some place.
So, lash caps allow you to do that.
The Honda 600 Sedan’s first sold in Hawaii were 45hp engines, meaning they had a larger carb, longer duration on the cam and the Y exhaust system (using a angle port head) all of which made the difference between the 36hp engine (California spec) and the 45hp engine first sold in Hawaii.
Chassis/Engine numbers from NXXX-XXX-XXXX N600E-1014095 through N600 1018285 N600E 1017730 and some of the numbers in-between were not delivered to Hawaii.
They included chassis numbers going to England and Australia (from the information I have been able to gather).
But it’s the engine numbers that tell how many were actually sold in Hawaii as Honda made their engines specific to country regulations and that would make it about 3635 Honda 600 Sedans sold in Hawaii in 1969.
In January of 1970 all Honda 600’s being built for the USA conformed to California EPA requirements.
That is not to say there weren’t Honda 600’s being modified by dealerships seeing the difference between the two and going to their parts people and ordering the necessary parts to make “Hawaii” engines for their cars.
In the late 80’s all these parts were still available in the parts book and could be ordered.

Hi Don;
You got it. Like I said, they also went to other countries, the 3635 number is the number of engine numbers between the start and end manufacture number date from the parts manual. Included were Japan, England and Australia (from the chassis and engine numbers I have collected from owners) I have not received any numbers for the 45hp Sedan in France, Germany or Belgium. The ones I did from France and Germany were 42hp engines and dated later build dates.
I was dating a young lady in Hawaii in Apr. 1970 who had one. I really didn't know what they were at the time but there were not many around. And she wanted to ride around in my Chevy Nova so there were not any choice memories in the Honda.
