I has piston ring question

[makr]

The factory Suzuki service manual is clear: The top ring is chrome plated and the second ring is not. The rings have a different shape. The ring end gaps are supposed to be the same for both the top ring and second ring.

The top ring runs hotter than the second ring thus it doesn't make sense to have more clearance on the second ring. Also, the top ring is under more load which is why it's chrome plated - to increase it's life due to the extreme pressure.

Sounds like you should have listened to those people trying to help you.

Clear as mud. That is why I asked. I will pull them out, and put them on the optical comparator, and see what the profile is.

By the way, the manual you referenced in your third post isn't the right manual for your bike. The '83-'86 GS550 engine is completely different than the '77-82 GS550 engine. It's a 16 valver with a plain bearing crank. The older GS550 is an 8 valve engine with a roller bearing crank.

That page says GS550E-ES/L 1983 at the top.

Why bother with a comparator? The chrome ring goes on top. Even if the ring profile is the same, the chrome ring goes on top anyway due to material considerations.

I don't know of any 3-cylinder BMW cars, so it must have just enough rings.

I had a three cylinder BMW bike, it was one of the good ones.

Because I don't believe anything I read on the internet until I prove it myself. For all I know you are a thirteen year old girl who between live cam feeds on a pron site, jumps on motorcycle forums to steer people in the wrong direction because your dad rides and he once touched you in your naughty spot so you are getting back at him vicariously though us. I don't know.


But if you are not a little girl...I did put it on the comparator today, and you are right. So I just changed all of them around...which means maybe you are not trying to steer me wrong to get back at your dad.
