Those are calculated numbers, what does a measured compression test show  & Is it hard to turn the engine over even on the down stroke, or only as it reaches TDC?  

If this is a new or escalating problem on a used engine; remove the exhaust header pipe to do a partial visual inspection of the piston rings and barrel to make sure nothing is seizing the piston.

Another cause may be that the compression is very high. I had the same problem with my 2023 Gasgas TXT. It seemed that it’d take a rhino’s kick to start it. I’m a small guy and it was a total workout for me. I lowered the compression with a 1mm head spacer and it’s very easy to kick now. S3 makes low compression head inserts for Betas that maybe you can consider.
