A piston is pretty much the same wherever you find it. It's a cylindrical lump of metal that fits snugly inside a length a pipe, a cylinder. By creating a pressure on one side of the piston you can get it to move, to transfer force. Pistons are found in combustion engines, where the gasses from the burning fuel push the piston(s) down an power the engine. They're also found in braking systems. The brake pedal push down on one piston, creating pressure. The pressure moves through a pipe into the brake caliper, where anothe piston cause a brake pad to move and push against a moving surface. Pistons are also found in shocks, where the movement of the piston against an enclosed gas/liquid slows the movement of the vehicle down in a controlled manner.
If you only use one piston ring on 80cc bike engine, the compression ration will be reduced.
well there should be an arow on the top of the piston which points to the exuast
right 45 degrees
No compression could be various things from your piston to your crank start with your piston by doing a compression test
You cant find replacement parts for that bike, but if its for a piston... a honda CR 125 dirt bike piston will help and fit, heights and dimensions are to the notch the exact same...
SAE 140 1 qt
That is a stock bore 93-01 KX250 Piston. The part number 617M06640 is a Wiseco number. I know as I have the same bike and this is the piston kit I used. Very good piston. Do not be suckered into a single ring piston as it will not last as long.
There are several things that can cause your bike to backfire and smoke a lot. The most common cause is broken piston rings.
its burning oil and needs new piston rings
Your bike can blow up. Because it has nothing to lubricate the piston
IF mantainance of the bike condition in in initual days of bike purchase was later cause u with engine comming to bore which means piston strokes are not suitting properly with the engine capacity.........
Your top end consists of piston, rings, wrist pin and bearings and clips.
