Yeah it looks like I'll have to.. Front is 73-74 shovel and rear 65 pan plus extra lights..

 

 

That wiring box for the front is the later style used on Shovel models. There were two versions. Always liked them. The circuit board is a simple plug-n-play and there is a lot of extra spaces that are not used, so if one takes a dump you can basically switch the wire/s around

 

Got done rebuilding the instrument panel. One thing I noticed was all the outsides of the bulb sockets were connected to power. The gap between the socket and base is pretty close. The 65 wiring seems to power the outside of the socket and use the center pin for the oil pressure, neutral and generator light. I'm going to rewire it so power goes into the center conductor and the others connections are on the socket. That way I only need 1 wire for neutral as I can ground the other side of the switch. The oil pressure switch doesn't change and armature is connected to the outside. That way if any of the bulb sockets get shorted to ground the light simply turns on.. The other way, the wire grounds out the the power wire.

Some of the socket bodies were loose. I dumped a bunch of green Loctite on the fiber insulators and let it work in then let it set up. They are all tight now.

 

The cylinder was worse than I expected. It's like someone bored the cylinder to size then didn't know they had to hone it.. I'm thinking if the pistons look good, maybe hone out the tooling parks and coat the pistons.. The cylinders are likely pretty straight.

 

This guy liked lithium grease.. Bike seems to have low miles on the rebuild but everything is black inside..

 

Pistons are 0.020 over..

 

Good luck with the honing of the cylinders. Nice that the cylinders are only .020 over, lots of metal to work with. Those marks look fairly deep, hope it goes well.

Yeah, It'll probably need to go 30 over to clean up.. One thing is that there seems to be a bunch inexpensive of NOS piston sets on ebay..

 

It's been cold and rainy here so I didn't do much work. Once the motor has been pulled, I've got other stuff to work on anyway.

I measured the bore without pulling the cylinder. It miks out at 3.464. If may calcs are correct a 20 over cylinder should be 3.4575 so it looks like I've only got about 0.0035 to do a fresh 0.030 bore at 3.4675.. Hopefully the bore is straight and perpendicular to the cylinder base.
