Looking good Craig. What are you running for a 12 volt battery?

[CraigArizona85248]

I run a generic brand AGM battery that cross references with YUASA YTZ-14S.

I'm getting really close to finishing up. Rear fender, rear wheel, sissy bar, primary cover, ignition wiring, top motor mount, headlight, and passenger pegs have all been installed.

Just need to install the gas tank and add fluids and it should be a wrap.

Wrapped it up over the weekend. Added fluids. Need a good day so I can take it for a quick shakedown ride.

One more change today. I have a repop j-slot air cleaner baking plate that I cut up and mounted to a CV40 backing plate. The j-slot air cleaner is what came on a 1949 Panhead and is a lot smaller than the S&S air cleaner I've been running. It doesn't cover up the motor as much.

I like the look of those air breathers.

an antique tag would do it justice

I had an antique plate in Arizona. It was made of solid copper. I'm not sure if Nevada has a antique plate for motorcycles. Even if they do, the DMV here is such a pain in the ass it's not worth the trouble.

After the 23 day tear down, inspection, and reassembly process, I started my old chopper this morning. It was a little stubborn since the temperature was 19F (-8C). It took 6 kicks to light. The flywheels felt like they were stuck in molasses. 60W oil is pretty thick when it's this cold. After it starts I closed the enricher and blip the throttle a couple times. You can see the motor expel unburned fuel and then it settles into a nice clean idle. It was a cold shakedown ride, but so worth it! This cheered me up today 😁

No sound during the portion of the video that I sped up. I didn't think you'd want to watch a 3+ minute long video.

Craig, after you changed to single plug heads did you notice any difference in your kickstarting routine? What was the motivation for changing from dual plug heads.

[CraigArizona85248]

I have 2 sets of dual plugged heads. After 20 years of using them hard, they are pretty much used up. Both sets have small cracks in the return oil gallies that allow oil to just sleep through to the outside of the heads. I decided they just aren't worth sinking more money into them. So I sourced a new set of heads and decided to keep these stock.

I did have to switch up my starting routine a bit. These heads like to have more fuel during startup. That's the biggest difference. A few more twists of the throttle before a couple primer kicks w/ key off.

The big difference is in fuel economy. I used to get 62mpg on the highway tank after tank. With the stock heads, I'm closer to 50mpg.
