Compression can vary between the two cylinders if the cam timing and valve clearances vary between the two cylinders.
If the cam timing has the inlet opening to late then the engine sucks in less mixture than it should so has less to compress.
A leak down Test is a better diagnostic procedure for checking the condition of Valve and piston ring sealing

I'll have a good gauge; bike went in with std bike but cam timing done, 60 hp. Now had same special cam timing but top end overhauled, squish set and 2:1 system.

think some engines are just 'good'. I maintain its how they are ridden when new. Harder the better straight out the crate!!
