WOW. That is quite a turn, and you weren't kidding about it being light bulb shaped!
Maybe see if you can find a place where you can get on a constant circle, set your speed and then try doing a slight, gentle roll-on, then gentle decrease of throttle, with your arms VERY relaxed on the bars, and observe how your line changes. Too much will make you go wider, but not enough will end up slowing you down and making your arc tighten. Cornering and wind forces will have the effect of slowing the bike, so holding the throttle FLAT with no roll-on at all will end up with the bike slowing down.
So, if you are smooth with it, you should be able to use your throttle throughout that whole long turn to widen or tighten your line as desired. If, at the end, you find that you are a little wider than you want, hook-turn would be very useful - have you been to CSS and seen that technique?
It is a challenge in a long turn to use enough roll-on to stabilize the bike and hold your line but not so much that you end up with TOO much accumulated speed at the end. If you feel like you are having to steer the bike back out, though, I'd try adding a bit of throttle instead and try to correct it that way.
Some good points there and that is a very good experiment to do, going around a circle and playing with throttle control and bodyposition aswell .. The thing is I feel I can carry more speed if I continuously countersteer and hold it throughout the whole turn and actually build some speed and even holding my line .. but I realize I am not supposed to do that but I do that when I have to pass people on those long turns so one countersteering action per turn goes out of the roof. It might be that the bike will stay in that line even if I do not countersteer but I am not certain. Yea I am saving up for the Level 1
