I've been thinking about this for a few months. The question is how to go about breaking in a rebuild on my 1982 R100RT. Back story....I needed a head rebuild so i figured it was a good time to dig in deep over the winter. I did a timing chain and crank sprocket change at the same time so I obviously had to take the bean can off which set myself up for a timing operation when i get things back together. Now i did take pictures of where my "alpha" bean can was set prior to disassembly so I feel i can at least come close when I reassemble things. Also, because my valves needed often adjustment prior to the tear down, I think the carbs are close to adjustment as far as the idle and mixture screws are concerned and i think I can come close enough to adjusting the cables by eye so the bike will be run reasonably well out of the gate. Oh, and I'm also putting in new piston rings at this same time. Here in lies my dilemma.
The info i read on break-in is to start the bike and get the rpm's up to 3000-3500 and then go for a ride, like a 50 mile ride. Snowbum make specific note to not idle the bike too much during this time. None of the write ups i've come across talk about timing the bike or adjusting the carbs prior to taking off. I'm confident but i'm not that optimistic that i will have set the timing exactly as it needs to be set and that the carbs are nicely balanced. That takes time with the bike at or near idle. Surely, I'm not the first to go this route. Please advise. Thank you in advance for all the great info that you will send my way.
