So I started getting into this engine. The engine is completely dry, or at least I have not seen any sort of lubricant in any of the insides. I started late so only go a couple of things off. From what I can see, it looks pretty good so far. The gaskets look dry and have no kind of sealant on them. I'll write more tomorrow early.

IMHO the engine's exterior should be spotless before opening it up to possible contamination

[jgonz]

Schming that's a valid point. There were a couple of things that took place before I got to this point, one of which was running around working on my water well, so my head was in several places at once and I rushed into the disassembly. However, my rationale for doing it like this is that it's a complete breakdown. All of it is coming apart, getting cleaned, bored, sanded, replaced, etc. Any bit of dirt or grease that is kept from the interior is not going to really affect at reassembly because it's coming completely apart. I do understand your rationale, though. And thanks for the input, please keep it coming.

Work continues:
I was working on the bearing caps which are numbered 1 - 5. On the exhaust side everything was normal but the Intake side had 4 and 5 switched. Is there a concern with wear on these or should I just put them in the right order upon reinstallation? Seems silly but you never know.

I'm working out of the pdf of the manual out of my computer. I'm going to print it out tomorrow so I can take notes on it, I usually like to write in the pages.

Hopefully I'll be able to start earlier tomorrow.

Just switch them back but for God sakes, get that sand off the cam lobes and oil those cams & lifters! I hope you did not turn that motor over dry with those abrasives all over the cams. YIKES. Clean the operating room for surgery.

Deebs, he stated that is was going to be a complete teardown. I've also done a teardown on a dirty engine. The cleanup is AFTER it's apart, as we don't know what may be inside.

[Radioguylogs]

I would switch the caps back to the correct (original) locations, expecting the clearances to be closer to to the original factory manufacturing process.

[jgonz]

Radioguylogs, I kinda thought that should be the case. Apart from the obvious stuff I found on the outside (suspect wires, cracked connectors, goofy repairs and crazy mods) I suspected there might be stuff to be found once I opened her up. My experience seeing other people's projects have has shown me that well meaning riders don't necessarily do the best jobs.

I'm going at a pretty slow pace just because I have only been able to get at her in the afternoon. I also hate working out of a screen so today I headed to the library and printed out the "Engine" and "Clutch and Transmission" chapters out of the manual as well as the Shaft Drive Service Manual that Cajun31 sent me.

Here are some pics of today's progress. Looking at the carbon build up I'm glad that I'm getting into this thing. Tomorrow I'm going to carry on and see what else I can find. I'm slated to travel this coming week so not sure how far I'll get. That means that I'll be able to order parts in about two to three weeks.

BTW: DEEBS11, I didn't answer your question about the shovel... yes and yes... I have that setup for almost 20 years. Originally, I had a dry clutch on that bike with the enclosed primary but I transferred it from that bike to a bike with an open belt. I put this little shop together last year out of a garage that had been damaged on my property. At that point I started taking parts that I had laying around and just put bikes together. I have a few that need little details and I COULD have them running if I didn't care about how they look, but with so many projects I just take them as I can. This particular shovel is very special for me. If you look at the suspension in the rear, it is not a very common setup. It is a plunger system that was usually found in choppers in the 60's and 70's. The paint was going nasty and it had other issues so I took it apart and am itching to get her back on the road. I'm actually wanting to set her up with an open belt. Following are pics of the bike as it was and the open belt that now uses that dry clutch (it's a kick only bike). that bike now has a springer front end.

Understood Ray, my thought was the need to turn the motor at all for head disassembly and possibly grinding the sand into the lobe face. That thing was mighty dry.

[DiverRay]

All the carbon buildup tells me the P.O. probably ran "premium" gas. These bikes are designed for REGULAR gas, and they DO carbon up if running premium.

[Radioguylogs]

...and so many folks belive they can improve the performance by increasing the jet sizes

[DEEBS11]

....or removing the muffler and revving the bike at every stop sign.
