Your readings seem high to me , but , I only have what my system produced to compare . And , that is likely not optimum .
If your readings are correct  , the headlight coil is producing about 162 watts and about 58 watts to the tail .

That should be way more than you need . Maybe enough to burn 6 volt bulbs .

I wish I could be more help . My bike is currently waiting to have the motor bearings replaced . I hear a whir on deceleration . I think it's either the crank bearing or the big end rod bearing .
Anyway , I won't be running it for a while , so I can't provide present day output readings .

Yep.  I think that's the way I'm gonna go. 

I guess on the bright side I have an old piston to practice on.   

And thanks for all the measurements.  They're going to save me a lot of trial and error.

You're very welcome . Just helping the cause .
Let us know how it goes and maybe post a few pics .

Good evening Pete,
Thank you for the complement. I do not have the Simplexes in a registry.
Thanks,
Scooter

If you post , or send to kartjockey , the motor and frame numbers , they could be added to our registry .


Pete .

Good evening,
finally after much searching have found enough pictures on here of all the parts to make the parts I needed. Because the slide has a tang on it at an angle I had to make several cardboard tube mock ups to get it right (or close enough).

Now that I have made the parts and assembled one it is embarrassingly simple though complex looking.

I have finally driven this 1956 that I fixed up in 1996 and it runs great.  It is easy to find why people like the automatic since it is easier to drive.  I do still like the challenge of the shifter.

Good you can ride that bike after 27 years .
I'm just guessing that you finally 'retired' enough to finish the project ?

You should post some pics or a video .

Pete .

That turned out real nice .

Pete .

Ha . I'm still jealous .
Some guys have all the great toys .
Nicely done , Tom .

Pete  .

I was planning on being there until about 10 days ago when we closed on a small house in a small western Arkansas town .
Being as we've been on the road for the last 12 years and sold or gave away everything needed for sticks and bricks living , we are now shopping for everything to make this house home . 
Ex : Just bought a new yard tractor to hopefully help keep the 2/3 acre lawn in shape . Delivery was due yesterday , but got delayed , so hopefully very soon .

Anyway , I hope all of you have a great time with excellent weather .  I hope to get to Portland again , someday .

Pete .
