Stock with wiesco .012 inch or .305 mm.
Your may not be that since sleeved.
When they sleeve it's close then they surface it down flat.
This is due to cutting top of Barrell for top of sleeve lip then press it in.
They best quick thing is match the transfer roof heights Most important for now
The corrected is based off what you posted to find the spot to start the degrees for adjustments.
As far as transfers and boost port when you match the heights radius them to what you have. Easy stuff.
In the last chart I gave the mean line to add to port map.
As a rule and on almost every pilot cylinder the best way to find BDC and then TDC (Top Dead Center) is the bottom of the exhaust port and transfers. The exception is a sleeved one.
When laying out out your timing limits I start with the cylinder on flat bench slid in piston. You should notice the crown edge right at bottom of ports. This is a very close BDC.
Then turn the cylinder over and move piston towards TDC (Top Dead Center). Then you can start setting the limits looking for ring lock pins if you marked them on top and bottom of piston and you can draw on cylinder the skirt layout. The only thing with with the ring pins is the amonut of twist for better word the assembly has
Here is where you find some power. And make sure your exhaust port floor is not expossed at TDC (Top Dead Center).
Any way match those transfer ports and run.
If so load your clutch for bottom end. If alt add one disc
If HRD add two. This will help on top check driven spring. If out of spec shim with carrier shims. This will help greatly. Don't over shim. You will now when you get it right.
If you start pushing hard out if cornor or lifting front back off one shim.

CDI (Capacitor Discharge Ignition), correct? If 90 tighten up your plug gap a touch as not to snuff the flame kernel. High pressure and fuel.
Enjoy your trip.
