i picked up a dt? 175 to use the motor in my tri moto...thing is its been sitting 20years and the piston is like rusted to the cyl.anyway to get it out ?

[El'Capitan]

you could try soaking it in PB blaster and letting it sit for a while. then trying to remove it.

[jeffatc250r]

Soak it with penetrating oil, take the head off and give it the tap tap with a piece of wood and a baby sledge hammer, should work its way loose with a little persuasion.

PB blaster or equal oil, hit it with a block of wood and a hammer like captain and jeff said. and i heard if you heat rusted parts it helps :wondering.

[grafitti911]

but aluminum if you heat it it could warp the head or the piston pb blaster let it sit for 2 to 3 days n a block of wood n a hammer tap the piston loose if that dont work let the pb blaster sit for a few more days

true, so only use heat as a last option when you cant do nothing else right?
