Hi. There is two ways to determine compression. A dry test and a wet test.
Check the compression dry and write it down. Squirt some oil into the cylinders and check it again. If the compression doesn't come up the problem is in the upper end, If the compression shoots up higher, the problem is in the bottom. ie:rings. (depending on the year make model
2 stroke 4stroke etc)Good Luck Vern

SOURCE: my dr 250 1984 has low compression

your carb got stuck and it sounds like your rings are burnt out like u were running to high of an octane or something in your gas

Have 250 2stroke polaris runs great on top end but sluggish on low end seems like it should rap faster

Remember it is only a 250 but a couple things will cause that problem I have found that 2 stroke engines tend to stop up the exhaust pipe try taking it off replace it with a shorty pipe to test it if it runs like a striped ape the pipe is probably stopped up take out the baffle and clean pipe and muffler good reassemble
then there is the chance that it is low on compression this would constatute a top end rebuild

I have a 1990 kx 250, just had the top and bottom end done. Rode it for four hours and it died! Replaced the cdi box with new one, replaced the coil and stator and I still have no spark'

chec battery-must always be at 12.6volts-any lower and bike wont function--inspect connections for corrosion--also make sure carb and fuel delivery are correct

My kx 60 wont kickstart but it will bump start

Sounds like low compression. Do a compression test,and it should have at least 90psi,..if not,its time to rebuild the top end..(piston,rings,bore)...pretty common for two strokes.

anything over 120 on compression test is ok. anything under 120 and its time for top end. and for bog you might try cleaning carb.

sounds like you might need to rebuild the top end and check the rod bearings remember when doing a top end always change piston and rings and use new base and head gasket

New top end but no compression or very little

Sounds like you have the crank to cam timing incorrect. Also you may have the valves set too tight. Dose it pop and sputter?
