Not in this thread. I actually looked before I posted. But no harm. Now countless people across the internet know how double images can happen on pre bean can ignitions--unless they read Duane's write up on the subject and they already knew.

No number is more "countless" than zero.
Zeros don't count?!?! I wish I had $10,000,000,000,000,000,000 for every time somebody said that!

You could almost bail out the govermnet with that kinda money.
Well I posted on June 20 that I decided to change the timing chain on my 82R100. It was still very drivable but it looked as though the split timing image was talking to me, saying "change my chain". I ordered parts from Chicago BMW and got them about a month later. Parts I decided to just change whether needed or not were:
chain, engine sprocket, chain tensioner pads, tensioner spring, tensioner piston, timing chest seal, new woodruff key for the new sprocket.
The autopsy showed: 1) Very stretched chain compared to new 2) Engine sprocket with sharp teeth and a wierd angular wear pattern. 3) Tensioner pad under tensioner piston almost gone
Hardest part about the whole job was getting the old sprocket off. Turns out the power steering pump puller I had planned to use didn't have enough reach. My old 3 jaw puller had worn pulling surfaces - a chaepy anyway. Got a new puller ( strong like bull ) used the large hose clamp trick, heat tighten, more tighten, get pissed and then really torqued the puller and POW. She broke loose.
Getting the new fish clip on the new master link was a little tedious but with stuff that small what do we really expect?
I used momma's oven to get the new sprocket up to temp ( I used 300F ) and had to run to the garage with the sprocket in an old towel. Bam - slid righ on the first time. I set it with one tap of the hammer using a piece of 1-1/2" sch 80 pipe.
After re-timing the R100 is back to life. Runs MUCH better. Idles smoother, doesn't take as long to smooth out from cold.
No timing chest leaks yet, no stripped bolt holes, the new chect seal went in straight.
This was the first time I did a timing chain on an airhead and although time consuming and hard on the back ( no lift in my garage ) it wasn't that hard. I just had to go slow, working a little every night after work, and triple checking my own work.
Advice for people thinking about doing this job for the first time: Make sure your puller has a 4" reach. Use more heat than you think you need for pulling the sprocket off. Job is about a low to medium level of difficulty.
Glad to hear it went well Ray. Thanks for the feedback. That's a job I think needs doing on my R100/7 and I've been dragging my feet. I'm feeling inspired, though I'm pretty sure the feeling will pass soon.
Ken

Ray, when I tackle a job like yours for the first time, I always plan to do it just like you did. Do a little, sleep on it, think about the next step, do it in my head, think of all that can go wrong then do the next step. Sometime it goes so smooth it's like you've done it dozens of times. Almost never a disaster using the slow and steady method with mental rehearsal.

That's a good point and a good formula. And to it I would add beware of tiredness and/or crankiness moving you away from the formula.
