Many, many years ago, I owned one of those little Jawa's.

They reach 45 ~ 50 km/h (28 ~ 31 mph) even carrying two adults.

Up-hills were not problem in second or first gear.

I would pressure test the crankcase, those crankshaft seals are probably too hard to prevent leaks (worsening performance at low rpm-wide open throttle).

I would verify the transmission for all gears by turning it by hand.

These little engines are more sensitive to poor rings-cylinder seal that to off-timing.

Best !!
