The main thing for you to decide on is which break in system you are going to use. If you use some type of heat cycle method or something like that then you are going to have to follow their system. If you are using my system then you mentioned that you are only on tank 6 or 8. So you will note that I make no mention of temperatures in my guide and you should not be worried about the temp that you are running at as you are just breaking you engine in. Even after it is broken in temp is just used for a reference and that is it. If you think about it what is more important, an engine that is tuned and runs properly or an engine that runs at a certain temperature lol??? If you think about it if your engine is running properly, blows good smoke, clears out properly, never lean bogs and runs exactly the same for 30+ minutes who cares what the temp is right? So I would not get too caught up with all of that.....

In regards to your last question if your air gap is too large (for the amount of fuel being provided by your LS needle) that would make for a lean condition. This would normally result in hotter temperatures. Unfortunately usually people that are not that experienced with tuning tend to run a lean bottom end with a rich top end. This keeps the overall engine temperature low but wears out the engine quickly. Again best bet if you are not sure what you are doing is to read my break in guide and follow it step by step.
