Hello 2stroke
Here it is my "all purposes" curve : the engine runs smoothly on the whole powerband.
Ok that is almost similar what I have now with the stock ignition (set 5 degrees more)
Roughly drown it into your map in blue.
I've developed this map to optimize my track-bike setup about two years ago, since I can't increase anymore the advance by adjusting the pickup position on the stator. Moreover this mod increased the advance at any engine rpm, that was not optimal.
Here it is:
TDR has a different map than the one stored in TZR stock CDI, it's more similar to DT 125 R (3BN) one. So I took the TZR 4DL map and adjusted it by increasing the advance of about 6 degrees, only where required, plus other small changes. This was a good start for me : I developed many maps that brought to the dyno I've shown above in this post. They're quite "extreme" compared to this one...anyway not for "beginners": engine is pushed to its limits, as it's only required for circuit racing.
For the moment you may like this "intermediate", as a reference for your developments

Be very careful with carburetion...
@Martin :
My track-bike peaks at about 10500 rpm, but pushes strongly over-revving to about 11500, where reaches the top speed. I' ve set the rpm limiter to 12000, quickly reacheable on first 3 gears. I decided to use stock expansion to have more "shoulder" at midrange. With a Giannelli pipe, the bike peaked at 11000 and went overrevving to 12500. No need to go that high, otherwise you have to do an intense use of clutch, coming out from circuit curves.
I measured static angle that is the same between TDR and TZR Belgarda (3MB/4DL), since they've same flywheel and stator with a huge lobe. Mine is 80.5 degrees.
