I get that logic. It was the same with my old TW, which laid on it side. In a field. For 10 years. Ugh.
I actually got it to run and rode it for a season before tearing it all apart.

So I had a few hours to do some more tinkering on the Scrambler. The swingarm pivot bolt is the only place I've found grease that was still recognizable so far. That one came out pretty easy. I got the front triple trees off, and like everybody else who does that job I dropped the steering bearings all over my garage floor.
 Found them all (I hope) and got everything bagged and tagged. The races looked really bad at first glance, but it turned out to just be old petrified grease and dirt. I cleaned them up with a brass wheel on my drill and they look great. I had thought about replacing them with a set of taper bearings, but I think I'll just stick with these for the time being. As I mentioned, I remove the swingarm to start breaking down the rest of the frame and getting it ready to spend some time addressing the rust. This is where the bad news keeps on coming. http://www.chinariders.net/attachmen...1&d=1540812958 I'm going to need a new rear hoop.  I realize that of all the things I'm finding (or not finding, as the "it's all there" post was written) needing a new rear rim isn't the end of the world. It's just a little irritating to me personally that I didn't notice it when I went on my mini shopping spree and ordered a boatload of parts. Oh well, It'll all have to get done sooner or later. As for the next steps, I'm going to be tearing into the carburetors (which actually don't look like they were out in a field for 25 years), and finishing up the frame strip down. I'm also going to be calling a local welding and machine shop to see about getting the upper triple clamp welded back together and the brake cable boss on the front brake hub repaired. And so the adventure continues!

A few more stray hours in the garage today. I managed to get the rear brakes all broken down, with an emphasis on the broken... Same thing on the rears as up front. The friction material was completely separated from the shoes, and the pivots were all seized up. I actually wound up drilling the shoes next to, and parallel the pivot pins, then hammered a flat blade screwdriver in the holes to break the shoes away from the pivots. I managed to do surprisingly little damage to the pivot pins, and I figure that the little bit the drill bit did catch the pins will just hold that much more grease when it all goes back together. The next thing to happen will be to finish stripping the frame down, then I'll start working the rusty bits with a wire wheel and some etching primer. I think I'm going to paint the frame gloss black (yeah, real original and daring, I know), along with the wheel spokes and cylinder section of the engine. I'm going to leave the wheel hubs polished aluminum, and the rims will be polished chrome. I haven't decided what color I want to paint the side covers and tank yet. I'm kind of leaning towards either a sunburst yellow, or British racing green. That's still a long way off yet. The next thing I'm going to get is a sandblasting cabinet from Harbor Freight. That will be a huge help in getting all these parts prepped and back together. But I can't get that until we get into the new house. I have a meeting with the builder on Thursday, and the timeline should lay out for us to move in around the middle of June. Fun times!

As usual, any time spent working on a 40 year old bike will have some good news, and some bad news. First, the good news: The frame is now 100% stripped down and cleaned up. The weather out here in Phoenix is getting a bit chilly, but still nice enough for working out in the garage, and more importantly, still nice enough to shoot some paint. I got the rear swingarm cleaned and painted last week, along with a few other odds and ends. The frame will get painted this weekend.
http://www.chinariders.net/attachmen...1&d=1544098701 Now the bad news: The rear brake pedal has a pivot rod that connects the pedal to the frame, and also serves as the pivot for the centerstand. As you can imagine, the bike being left outside exposed to the elements for 25 years didn't do it any favors. The rod was completely seized to the brake pedal, and I had to use the trusty angle grinder and cutoff wheel to get it out. http://www.chinariders.net/attachmen...1&d=1544098882 http://www.chinariders.net/attachmen...1&d=1544098882 http://www.chinariders.net/attachmen...1&d=1544098882 This leaves me with two problems now. 1) The rod is still stuck inside the brake pedal, and needs to be removed so I can fit a new rod, and 2) I have to find a new rod that is in usable shape, or have a machine shop whip one up for me. Surprisingly, there doesn't seem to be many machine shops out here in Phoenix. They mostly revolve around heavy industrial or production industries, and as a result a guy walking in the front door with a unique job isn't something they really jump on. Once I get the frame painted up and ready to go, I'll be able to start on the reassembly phase. I'm going to order the wiring harness and a few other odds and sods this weekend. I'm going to have to get some time set aside to dig into the engine, as well. That's going to require a complete teardown and overhaul. I also need to get the massive dent banged out of the exhaust system. It's a process, no doubt about it.

What is unique about the rod? Does it step up or down? Can it just be a piece of DOM tubing? I searched for it on BB, but only found a 350, not a 450. Tell me if the diagram matches what you have.

It's about 9 degrees F out here today with 20+ mph winds... what is "a bit chilly" in the South?

Item 13 on the parts breakdown. It steps in two places to capture grease.

Weld, I sent you a PM about the parts. Thanks!

Just to update everyone that I have nothing to update about, I took this week off because I was going to get some work done on the Scrambler. It didn't work out. The Bambino was sick on Christmas Day, and didn't want to do anything but cuddle on the couch all day. If you put him down for any reason at all, he would just stand there and cry and scream with his arms up. We think it was a combination of something he ate, and his molars coming in. He's got eight teeth in there now, so I can imagine things are getting a bit crowded for him, and causing him a bit of pain. I also went into the field on Thursday to help out one of our cooler account managers. He managed to take a piece of business away from a competitor, and wanted to get me in there pronto to install the equipment. Long story short, there was still a ton of the old chemical left over (because that's the way this particular competitor operates, they undercut the price by a huge margin, but then order a couple thousand dollars worth of chemical to sit on the customer site), and I won't be doing the equipment install until the middle of January at the earliest. Back to the Scrambler, maybe. I was out in the garage a few times, and came to the realization that I don't have the stuff I need to get it back together as a roller, and so all I can really do is finish cleaning and painting the frame. Great! I'll do that!... But wait. If I paint the frame now, it's likely going to get pretty scratched up between now and the move into the new house, and even more likely during the move to the new house... On top of that, I don't have the parts needed to overhaul the new forks I picked up, or get the brake hubs cleaned up enough to go back together. I also don't have brakes for either end, or wheel bearings, or a new rear rim. ::Sigh:: I guess this project is going to go on the back burner until we get into the new house and I get a couple workbenches built so I can lay out some of the parts, and maybe tear into the engine. I also need to pick up a sandblasting cabinet and an air compressor to run it. A parts washer is likely also in my future... So there's my no update update. Thanks for coming along for the ride.
