I don't believe what we are discussing is illegal. What is the "bike" so far as the government is concerned? The headstock, it is the only part with a VIN and is a significant and critical part of the frame rather than just a small piece with a stamping. You have two bare frames, one with a clear title in your name but is damaged (bent, rust, etc.), another which is in good usable condition, not reported as stolen, and you purchased with documentation such as a bill of sale. This is sufficient in many states to title or register the bike with feasible and minimal hoops to jump through for government to recognize you own it and allow you to use it on public roads... But not in the oppressive police state you happen to reside in. In that case you can use the parts from the parts motorcycle (parts frame) to repair the motorcycle (frame, headstock) which the government will allow you to use. At which point you can finish restoring the bike. This is fundamentally different than taking a complete ride-able and restored bike with unknown history, no proof of or history, ownership, or reported as stolen, and changing the headstock to one from a bare frame you own with clear title in your name.

The Cibie headlight, Philips bulb, and relays are... Awesome. Bright light, wide pattern, clean cutoff to not blind others on the roads, just amazing. I put the K1 with upgraded headlight next to the K5 with stock headlight and compared one to the other and there simply is no comparison. The stock headlight is like holding a candle in a storm, a tiny poorly focused splotch of dim yellow light. The upgraded headlight makes it almost like daylight in front of you. No idea how I rode all these years with stock lighting.

I've been told the turn signals are a little hard to see on a bright sunny day. I'll be upgrading those to whatever the brightest LED I can find are and adding diodes for the indicator. I had trouble finding a flasher that works with LEDs for my truck, so expect a little trial and error to find a compact one that works for the bike. I find the neutral light and turn signal indicator a bit hard to see in bright sunlight. I recall I used incandescent bulbs for those. I may try LED in those. I did not use LED for any of the indicator lights as I didn't wnat them to be obnoxiously bright at night and become distracting or harm vision. With that in mind it would probably be prudent to use one at least for the low oil pressure indicator...

Also changed the Motion Pro clutch cable for a Honda cable. This seems to have slightly reduced the clutch effort, which my wrist greatly appreciates with the heavier clutch springs.

Did you build the relay for the new headlight bulb you installed or for something else? I'm looking at upgrading my sealed beam and checking out options. Thanks!

Thought I would update on my frame. All I had in mind with restoring my frame was fixing the damage the PO had done to it. This involved fixing the seat frame and the right side down tube. It would have seemed easier to replace than fix but I took it to a specialty welding shop and they did an amazing job of restoring the frame. After powerdercoat the frame is good as new. No frankenbiking!
Why do the pics post upside down and then show corretly when you zoom on them?

Wow! That's excellent mate, looks like money well spent. I hope mine comes up as good! Cheers, Terry.

Great job of saving that frame. You should be proud of that.
What the hell was PO thinking with that RH downtube & seat area??

Apparently inseamed challenged I am betting and he modded the frame to drop the seating a couple inches with a drivers seat and pillon seat would be my guess.

Would have been much better if he had learned to weld first!
