Rings upside down?

[RID3R]

Is there a such thing that piston rings can be put in upside down? I was told that if your piston rings are upside down you can cause overheating. I never heard of piston rings being upside down

yep, the tapered edge should be facing up. it ussually causes low compression though. you also could have them in the wrong order. there are lots of reasons for overheating what kinda bike is it?

some motors you can cause problems for sure with like for instance the hondaline 300 rings mucho important that they go the right way!

the rings are what contain the cyclinder compression and combustion gases and explosion from going down into the rest of the motor. if theya re on incorrectly they will not be able to do their job and thus cause a multitude of issues. from overheating, to destroying a motor and anythign inbetween. I've seen cyclidner walls scoured from piston rungs installed wrong and I've seen them not do anything except just not hold compression very well. Also the gap wher ethe ring ends meet should NEVER be aligned up. thet should be opposite from each other at all times. this can cause a blowby gap and cause compression loss as well.

Im gona need someone to show me pics or somthing on whats the top and bottom of the rings for future projects. I dont have rings in front of me now but from what I remember both sides look the same to me. I had rebuilt my tecate and it was overheating a little and I was told about the rings. Its all good now, im just retarded and didnt fill the radiator up all the way lol I was just wondering if there was such a thing as rings being upside down.

if you look at em close you'll notice the top inside edge is beveled (top ring on both 2&4 stokes and second on 4 strokes). they are usually marked with a small dot or T right by the gap. chrome looking ring goes in the top groove and the dull or black ring in the second groove. as for the 3rd (bottom) if aplicable (4 stroke) it usually doesnt matter on most.

So you said it could cause low compression? I wonder if I messed up in putting my rings in when I put the 10.5:1 wiesco in my 350x :wondering . The reason I'm saying that is because my bike isn't any harder to kick than when I had the stock piston in there (and my compression release doesn't work). Also could this cause a little smoke on startup? I also had it smoke after I rebuilt it too. Just wondering if that could be the problem or what I have been thinking maybe the valve seals.

So the side that has the dot or T faces up?

You have to specify wheather this a 2 or 4 stroke. On 4 strokes, yes you want top rings opposite of each other to reduce possible blowby. On 2 strokes you have ring locaters that almost always are located to the intake side and not in line with any transfers or boost ports. This keeps expansion rate down a bit on the ends of rings, since they're cooled by incoming air and fuel. And lessens the chance of snagging a ring when things begin to loosen up after many hours of wear and tear.
