Looks great! In a few more years, no one will know what chrome is. So many shops have closed.

Pretty cool. Always great to try to make similar parts to keep them looking like they did. I did not know what the earlier ones looked like.

Thank you for letting me know that.
I wish I were neighbors with Wayne. A lot to be learned.

Good evening Ron,
I am with Rick on that gear. Unless you have a way to make and weld a new flange on the gear, that one no longer will stay centered and will probably damage any repair you make to the threads on that expensive hard to find a replacement for flywheel.
That gear centers up using three holes in the flange to fit the three studs on the flywheel.
Hopefully thread inserts will fit, otherwise custom made ones might be needed.
Good luck.

Thank you, the tapers were difficult because I do not have a way to measure exact so I glide the cutting tool along a good side until it matches. I recorded the angle of the tool post, but found I wrote down the wrong number when I got to the flywheel and had to do the angle check over and some slight adjusting with the lapping.
I think the angle is near 5 degrees.
I am glad there was some keyway left for the breaker cam to use as a guide to line up.
Now I am just jealous of Ricks set up. I have always wanted a mill, but have not bought one because I can use the one at work.
Thank you,

I inherited this lathe and all tooling from my Grand dad. He taught me to machine.
I have a small drill press and bandsaw and a 6" lathe I bought.
love to machine.

I made a new headlight coil and ran it. It only barely lights the 21 cp bulb. It is 10 volt at 1.35 amps.
The amperage is low so I am wondering if my magnets are weak even though I have good ignition spark. Probably not going to mess with it anymore unless I get the flywheel charged.
New coil is:18 gauge wire at 297 turns using approximately 88 feet and .56 ohms. I made it longer also. The core is 1.00" and finished out at 1.85 x 1.85 x 1.05 long. This size is almost too big and close to rotating magnets.
Old coil is: 22 gauge wire at 310 turns using approximately 81.5 feet and 1.3 ohms and core is about 7/8" and finished out at 1.43 x 1.35.
When I installed it I was wishing I had shimmed the wide side where the bent tab goes about .015 more. It was hard to push on.
Attached are pictures of the fixture to wind it and you can see the shims I had to add because the core is a little bigger than half inch and is wider in one direction. The carboard core in the picture is from the original, I forgot to take pictures of mine.

Good evening,
The bike is running again. A welder welded both parts for me with MIG, but I had to redo the flywheel with stick because he was not able to see in there. I machined and lapped them. I was planning to spend hours hand filing the flywheel keyway, but realized I had a hacksaw with a deep enough throat and could stack four blades. When I was setting up in the vise, I realized I could use a piece of plywood that needed behind the flywheel as a guide if I cut a slot in it. Took 10 minutes and made a very nice keyway I had to file about .005" wider to fit the key. I made an aluminum key for it.
In the process of putting it back together I found what happened. I forgot to put the washer behind the gear nut and the gear had heavy rust damage to the unused threads and made me think I was tightening it.
I almost did the same thing on the repaired parts, but this time I was checking fit up and making sure there is enough thread because it ends right at the flywheel and now my flywheel is a little further on the taper from the repair clean up and lapping.
I ran it for a while and checked and seems to have stayed tight. Also used blue thread locker on the nut.
Thank you,

« on: October 28, 2023, 03:33:41 PM »
I turned the bearing around so the thrust would be in the correct direction and have about .015" end play now.
My inner bearing is Koyo 6205 and no spacer. I did see a note in the manual that eventually they did not need it.

Good morning,
It is a Timken R1304. Do you know a number of one that would normally be in there? I can compare them. May be better when installed the correct way.
I wonder if it is why the parts book shows three different bearing numbers?
I did not measure the endplay. Probably 1/8".
I agree about not pounding them out. I drove it out because I checked it and moved with light force. Otherwise, I use a couple of propane torches because I dont have a grill.
Please let me know.
Thank you,

Engine & Transmission / model M right side bearing inner race direction
« on: October 27, 2023, 05:03:14 PM »
Good evening,
I noticed a lot of end play on my crank shaft when fitting up parts and I think the right side bearing inner race was installed on the wrong side. The inner race was facing the inside of the engine and I was able to drive the bearing out, but I am thinking the inner race should be facing the flywheel.
I cant tell from parts books, does anyone know. Refer to attached image of bearing.
Please let me know.
