Those side shots are kind of loud. This was the only way we could communicate with the bike running.

It's OK Chris, I did mention that they just happen to be my size anyway.

Since these parts came from other builds that ended up getting changed, it has wide fin 1250 jugs from Sbdo George's first or second Hammer build (500 miles on them). The flat top pistons came from a first 1250 build on Corona George's bike that ended up being redone due to slight valve contact (barely noticeable valve impressions) (2000 miles). Corona George came over after work one day a couple of weeks ago bringing his mic's from work. The jugs and pistons were all within .0004, so I swapped pistons and their rings into the wide fin jugs, aligned the ring grooves and assembled them for the build. The other jugs and the 30 degree domed pistons got set aside possibly for the Pig some day.

I also had a set of 1200 heads that Corona George had picked up on line, and he decided against using them and sold them to me for what he paid (sweet deal, thanks George). I pulled valves, ported the heads (they were really sloppy from the factory, with the rear head being twice as bad as the front). Then I lapped the valves and installed with new seals, and set those aside for the build.

I picked up a lot of parts after David (ocgreenmachine) wrecked his fresh build (like 350 miles)? Those include Pingle, 560 cams, bronze pinion, HSR-42, some other parts too, that will eventually go on the Pig (the blue Roadster). This bike is the Mule.

Then I started piling up everything we would need for the build, and when I got to the carb, (last item), I decided I better make sure there wasn't any gas left in it, and then I found it! The throttle didn't want to move at all. I thought it was frozen shut, but then I realized, no, it was frozen open. So I spent a while taking it apart one piece at a time looking for the bind. Wasn't the shaft as I feared, so I kept removing parts. Then I pulled the slide out and it was difficult to pull out, and as it came out the brass ring dropped to the mat on my bench along with the rubber spring washer that is supposed to press both sides of the slide against the faces in the carb body. That washer was expanded to where it was not in it's own groove, but it was between that brass ring and it's own recess. That was the bind.

So that washer was huge compared to it's original size. I can only assume carb cleaner got to it previously. I cut a piece out of it, and super glued it together for now to make is smaller, and I ordered a new washer, assembled it, and it works fine now.

Then as I was texting this to our little group, I realized that the carb didn't twist itself wide open inside the box on a shelf in my shop and get stuck there. It had to have been stuck when it came off the bike or before it went into that box, and if David had played with it, there is no way he would not have felt it hanging up like that (it was hard to move at all). So, BAM, that's what took him down. I said this to David, and as I am sure he will tell you, he thought, that sure explains a lot. He was entering a turn on the freeway and then he was plowing dirt and tumbling. He didn't know why at the time.

That was the interesting part of the story, the rest is boring stuff. It took us 9.5 hours on Saturday, and another 4 hours on Sunday 13.5 hours total. Everything is broken in already, except for the rings seating to these different jugs (I figure that will be minor). This weekend coming I will change the oil, I left the old oil in for now, it is clean and its only going to be there long enough to flush anything that needs flushing into the filter.

Sbdo George, Richard, and I worked together until Chris got there at around 4. Good timing because us old guys were getting wore out. Chris was all, we got all night, lets get this done! My mind was like OK , but my tired ass was like O crap K . So Chris kept us all up past our bed time (bad influence, but damn good friend to come all the way out there and work so hard on this.) Sunday, George, Richard and I finished it up slow and careful.

The end result is a real kick in the ass. Especially with the 883 gearing, the front is feeling very light when I get on it hard. It feels really good on the freeway (a lot like the Pig does in the way it accelerates in between traffic because I can't just go WOT through there, very responsive).

Maybe this is a scrappy mule now, since it's built from scrap parts.

Thank you guys. What did Richard say? It takes a village to build a barn? This is a damn nice barn, thanks again everyone.

Oh, check out the breather vent in the picture. That was a blooper. Turns out the Mikuni has the adjusting screw under that down tube. So I had to move it to the other side today to check idle adjustment. So far that is the only thing that needed attention.
