You've probably already found that every person has their own way of doing this lol but I'm not a big believer in trying to get the engine up to a certain temp when breaking it in. This is simply for the fact that the way that these engines work is that temps are dictated by both the load that you put on the engine as well as how lean you run them. So to me, logic dictates that if I want an engine to run at say 220 while I'm just putting it around at 4-5 mph then the engine has to be really lean! Like lean enough that if you were driving it at race pace you would probably be seeing 300+ degree temps. Again to me it does not make a lot of sense to break in an engine at a leaner setting than I would probably ever run it at even when fully broken in lol, but that is just my way of looking at things! I'd just wrap the head, set the thing really fat and slowly but surely start leaning it as you start increasing the load each tank but again that is my way of doing it. I'd check with the importer of your line to see what they recommend and follow that system if you can.
