There's always that moment.
That being when all the pieces parts are back in place, you've followed instructions, suggestions & good advice, thought it through, said your prayers; so all that is left to do is pull the trigger.
I just did that. And the R65 did that. It's alive! [smiley=clap.gif] Just had to tell someone who gets it.
Along the way, I...
Overhauled the 32mikemike Bings and corrected the one-cylinder start-up issue. MotoBins parts all the way.
Replaced the timing chain and several related parts in the timing case. Conquered an early fubar when I failed to mark the sprockets prior to yanking the chain. Thanks to several R65.org'ers and an Airhead or two. Again, a MotoBins timing chain "kit". Highly recommended.
Fixed, kinda, the boogered right-side exhaust stub and replaced the nut. RePsycled BMW to the rescue.
Replaced the stator brushes. This required purchasing a butane-powered micro torch to heat the steel plate (a natural heat sink) that the copper leads are soldered to. Good circuit test.
Shimmed the semi-wobbly sidestand while the exhaust was removed.
Rereading this post, it doesn't sound like the hefty chore it really was for me. I photo-documented the timing chain job and will post to the Wiki soon. Right this moment, I'm going for a ride.
Thanks to all my friends here at the R65.org asylum. I truly appreciate each of you and all the assistance, ideas, help and support.
BTW, this swine flu media event has an up-side for my wife and I. School has been shut down until May 11. Next chore is to finish the prep and paint the '83. May even get close to that this week.
More later. Thanks again, folks. Monte

Glad to hear that you got this fairly well wrapped up, as a project .
Nobody goes into a new job knowing everything, we've all been there !!
I've been wondering since you posted about the sprockets moving during the chain replacement, if when the timing chain is replaced, if a cylinder is on the compression stroke, if pressure is built up in the cylinder, after removing the chain, the crankshaft sprocket will move due to no 'load', and the piston moves to relieve the pressure in the cylinder.
You may want to remove or loosen the spark plugs to release any pressure in the cylinders, before removing the timing chain.
The time off is great, as long as you still get paid !!!!

It's great to finish a rebuild like that. Sometimes the simplest sounding jobs seem to take the longest. So when are we going to see some pictures of this beast? You know, the before kind, like the skinny kid on the beach who always gets sand kicked in his face. Then after you finish the paint it will be like the Charles Atlas guy. Or Nacho Libre', take your pick.
And watch out for that Mexican pork poison going around! Let's blame in on Ross Perot and NAFTA.

First very important order of business is, yes, we are definitely gettin' paid. [smiley=clap.gif]
Second, Yes. Any cylinder pressure could cause the crankshaft to rotate just enough to screw you up. With the chain removed, I was surprised at how easy it was to move the crankshaft assembly. One cheesy little ol' tooth can do some serious damage to valves, pistons, etc. Pays to dial up top gear and s-l-o-w-l-y rotate the engine while you feel, and listen, for any resistance.
BTW, the crankshaft sprocket mark -a tiny OEM 'scratch' on a tooth- is all but invisible. Add a good mark of your own next time you're in the timing chain case.

Nice job done there.
Just as a matter of interest, the cylinder compression no longer esists after the piston is put TDC, it is only there for a very short time when the engine is static, the pressure is built because of the speed it is compressed, turned over slowly, there is in fact NO pressure on the head.

well done monte, the timing chain was one job i didnt do on mine.
and yeah, when are we going to see pics!?

Drafting and crafting a Wiki post right now. May have to get some add'l assist from Justin if I stub my non-compuKer toes, but it'll show up pretty soon.

Great to hear the (full) Monte job is done. Congratulations!

Now I've just GOT to finish my project.

Yep, there's nothing like doing a job, or number of jobs ,and have it all back together and working and taking a nice long ride. Glad to hear you're there. Your diligence at documenting your work and posting it are a real help for us less-experienced types.
Keep us informed of the paint job on the "83. Your earlier posts were a great guide for me geting my ratty looking side panels looking sharp.
Happy riding! [smiley=thumbsup.gif]

I just want to add my congrats to you Monte for jobs well done!!! It does feel great doesn't it?!
