Compression testing

I have a little gt 80 that im forever messing around

i done a compression test on it and it read 50 psi and dropped straight away.. i know its supposed to read in and around 115 psi…

Its fairly straight forward to do a compression test or havi i missed somthing…. screw in tester and gauge… hold throttle open…. kick like f***… read results… or have i missed somthing.

If i havent missed somthing whats the next step… im guessing its a rebore and new piston… in a two stroke do you need to replace crank case seals ect? Or will just doing the piston and rings be enough….
