I've been quite busy with my engine recently. where to start!
I got the frame back from the welder a couple days ago, and since then I've managed to clean up the welds on the neck a bit. I only did this part because it'll show between the top of the seat and the tank, and I want it to look nice. I threw some primer on it to keep it from rusting while I get other stuff sorted out.
(P.S. I'm almost afraid to ask but: are the TIG welds in the first picture quality welds? I took it to a pro shop, the guy has a jig and 30 years under his belt, but they don't resemble the TIG welds I've seen online.) I used a wire fed to do the cosmetic welding. The TIG bits look like they have good penetration and are a nice concave shape, but I really don't know a whole lot about how TIG is supposed to look, so any comments on this are welcome.
Next, The carbs I bought showed up. They were in really good shape, but I gave a bit of TLC on some parts, mostly just putting silicone spray on o-rings to keep them fresh while the carb sits in a box waiting to be installed.
I also polished up some more ally parts. Here's some pictures of one in particular that had been spray painted with gray primer for some reason. As you can see the ally beneath the paint was in perfectly good shape.
Now on to the engine stuff!
I soda blasted the ally bits on the cylinders and took them to a local guru who helped me hone them out. Only ended up costing the DW-40 we used for cutting fluid. Really pleased with how they came out! I also massaged in a good amount of oil after honing to keep the cylinder walls from flash rusting while they sit in my basement waiting to be installed.
lastly, I took apart the heads with the 16 dollar valve spring compressor setup I put together. It worked well enough to get them apart, but for the reassembly I'll be borrowing a legit valve spring compressor so as not to foul up the faces on the valves. I was able to soda blast (baking soda) a ton of gunk off the heads and valve seats. I used a super low PSI when I did the steel parts of the head so as not to risk messing up the valve seats or valves. Also got the hardware cleaned up and bagged to make reassembly a breeze. Tomorrow I'm going back to the guru to lap the valves and seats so they'll produce the best compression they can. After that it'll be final assembly and... you guessed it... the head will sit in my basement until it's ready to be put on the engine.
For those who are curious the reason so many parts are waiting in my basement is because the bottom end is waiting on a crank I shipped out. After that comes back everything is ready to go, and I'm hoping to have the engine back together after a couple days. For any interested in following this build I post regular updates to an instagram account for this project called muckroute.
