89 to 94 kdx200

I took 3 compression test last weekend on my 200 1989 with CLOSED throtlle. the engine was warm.
3 times i got 175 psi with 3-4 kicks.The manual says 119-185psi is the usable range with full open throttle.(i read after the test)

Would the bike will have higher results if i do the compression test with wot?

thank you

Yes.

Sucking air thru a closed slide is going to get you considerably less air than thru an open throat carburetor.

Which is why basic compression tests include a WOT.
