Picture are good now
I have 2 of the same horn
Dont adj the screw in the back
The adjustment is the screw on front and locks in place when the nut is tightened
The Bosch HO/FDF is a great horn, very loud
Did you get your horn working

Frostman - I've heard a lot about that book - man it's pricey though. I've accumulated a lot of literature and pretty much have everything I need at this point - but I do hope to check that book out one day. Seems to be the gold standard.
CW - Thanks for the kind words. Glad you got your horn sorted as well.
I'm kinda hanging out waiting on my top end work to come back now. I was looking at the spark advance and thought it would be nice to have an adjuster there, since I don't plan to hook up the cable. I made up this little guy - which may have been a bit overkill. I really only needed one nut on it for example, since the holder is already threaded. Originally I was just going to put another acorn on the bottom - but there wasn't really room for it. Ended up going with a cotter pin. I'll use it once probably to fine adjust and then lock it all in place.
Hope the machine work comes in soon - I'm getting antsy.
Installed my filter and oil pan 1st, then put the rest together.
Exciting moment. I did slap one of those massive rare earth magnets Benchmark sells in the oil pan, which I forgot to take a picture of. The heads should be done soon - and I can't wait. I still find it a bit weird that the cylinder nuts don't use washers and the right side oil passage was never drilled. If I missed a thread somewhere about those two topics - I'd love to read them.
I did this just to triple check all my timing marks are where they should be. Makes it easier to set the right side gaps too.
In all the excitement however, I did discover a tactical error I made quite a while back... Once I bolted on the transmission and tried to turn the bike over, I realized it was slipping through the clutch. This puzzled me as its all new, so I had to get some second opinions and hit the books again. Turns out in my early research I overlooked that there are 2 different clutch plates used on the r69. Seems obvious now, but I ordered the 5mil plate thinking it was correct when it turns out I needed the 9mil. My motor does have the spacer ring, and after looking further, Benchmark even has this notation on their website about the 5mm plate: "R69 to VIN 653875". My motor vin is after this... rookie mistake that's now resolved.
Once all that got sorted - the motor went into the frame. Landmark moment and there was much rejoicing.

My original plan was to video the motor going into the frame - but see clutch nonsense above...
Think I'm happy with my shiny / grungy look. These exhaust pipes are glorious.
Dying to ride this thing.
