Remove head Remove oil pan Remove wrist pins and push piston up out of the head
no way. they are one time use only!
Remove engine, disassemble, replace piston, re-assemble engine and install. Good times!
You never replace a piston without replacing the cylinder too, as they're a matched set. The ones you want are for the 1600 cc engine.
Rebuilding the engine on an 86 Honda TRX 250r extends its useful life and performance. A typical rebuild includes replacing the piston rings and all bearings.
It is just about the hardest most difficult part of an engine to replace. The engine has to come out. The head has to be taken off. The rod of the piston has to be disconnected from the crankshaft. the top of the cylinder has to have a ridge reamer operated on it to get the piston out.
If you are mechanically inclined it is cheaper to replace the entire engine
Just replace the whole wheel cylinder. It's just as cheap and easier than rebuilding them.
Rings always need replacing during an overhaul. Why go to all the trouble without replacing the wrist pins? I would replace all parts that wear. Otherwise you are not doing a complete overhaul.
Yes, just be careful not to scratch the crank journals with the studs on the piston rod.
You don't. The only solution to damaged piston rings is to take the engine block out of the car and replace the rings.

The piston or spring on the thermostat could be stuck.
