Good evening,
Will someone please measure the wire diameter to make retaining ring for round taillight?  I made one and used too small of diameter and lens can still shake out so I thought I would ask before I make another one.
Thank you,
Scooter

Good evening,
Has anyone repaired the Phelon flywheel hub keyway? Or crankshaft?

I earned the fool of the year award because I only tightened my Phelon flywheel about half way to measure headlight coil amperage and about a minute later found that is not enough to keep from ruining the keyway on the flywheel and crank. I did not tighten it all the way because I knew I was going to be taking it back off.

I am disappointed it did not shear the key, but instead rolled it.  The key looks good. Maybe an aluminum key would have sheared. The crank and flywheel are very soft compared to other things I have worked on. 

I have not ever repaired keyways, I have always been able to easily make and replace the metal part that is damaged or buy a new one.  Not sure if mig welding or brazing the crank would be best and then cut a new keyway.  I know the shaft could be replaced, but would probably attempt to fill it in and cut a new keyway.

The flywheel really concerns be because trying to replace the hub and get it trued back up looks like a problem, but cant be used like it is.
Please let me know.
Thank you,
Scooter

Good evening,
Attached are images of the K model I (and also you for helping) have been working on.  This is where I wound up with what I have and figure it is time to move it to the restoration section.
I planning to paint it this year if time permits. I typically fix bikes up nice enough to where I am reluctant to ride them anymore, but I plan to ride this.

I prefer it be more correct, but for now, this is what I have.  The tail light, seat pan, kicker, flywheel cover and rocker pedal are wrong.
I could easily make a correct rocker, but left this one that is Late L ratchet with the K and early L detent cup welded to it as part of the history of this bike because I believe a owner did it years ago to solve a problem.

The flywheel cover came with the pile and appears to went to a model that did not have a hole so no kicker.  Since someone already put a hole in it, I used it and made a pinion cover for it.

The seat pan is 40's Harley and a little big.  I may cut it down, but if I leave it original size and stitch a cover for it, at least I can still put it on a Harley if I get a Simplex seat.

Thank you,
Scooter

Good morning,
I am wondering if anyone has a picture of motor pulley belt shield 1893? The parts book says it is used on all clutch models and I need to make one.
Currently I just have a spacer tube there for the stator plate.  What I do have for the belt is a guide that mounts to the carburetor and I think that is for the automatics which my auto does not have, so I can put it there.
Please let me know.
Thank you,

Good evening,
My K model has .017" wear in the middle of the cylinder and I am wondering if anyone knows who can bore that and have the oversized piston to fit it?  Maybe Wayne?  Has anyone had one bored out?  Any idea of cost?

I normally do my own resizing, but my machine will not do this since it does not have a through hole cylinder.

Please let me know.
Thank you,
Scooter

Good evening,
I have a Wico magneto that will not produce spark when the kick starter is used or the flywheel is spun by hand with the spark plugs out.  I have tested with plugs, with one wire grounded.  The wires are copper core and I have also tested it with short wires.
It has a nice spark when turned with a drill and will start and run.

It has a new (aftermarket) coil I tested at 1.3 ohm primary and about 9,000 ohm secondary.  It has new points gapped at .018 and I tried other settings.  It has a new (aftermarket) condenser I tested at .2 micro farad and I tried others with no difference. 

The flywheel seems to have enough magnetism, but I do not have another running Simplex that has Wico to compare.  The air gap between the laminates and flywheel is about .010, so that should be close enough.

Has anyone else experienced this? Or have any ideas?
Please let me know.
Thank you,
Scooter

Good morning,
I have gotten back to my K model project and have attempted to start the engine.  It will try to idle but is spitting a lot of fuel out of the carburetor.  It will not speed up. When I had the engine apart, I knew the rotary valve and engine case has a lot of damage and I think that is keeping it from running.
I am wondering what others have tried to repair these items?  I am looking for ideas before I try either making an oversized rotary valve and machining the case to fit, or sleeving the case to fit a smaller rotary valve.  Possibly smearing JB weld on the surfaces to fill in voids and refinishing to original size.

Please let me know of things that have been tried.
Thank you,
Scooter

Good evening,
Will someone please give me the correct spring dimensions for the later shifter bikes (K model) that go on each side of the pulley assembly and connect in the frame tubes behind the engine?  The ones I tried just fall a little short of having enough tension.

Mine are: .535 OD X .079" wire and have 10" free length hook end to hook end and the coil part is 7 1/2".  Refer to attached image.
Thank you,
