I now have (I think) all the parts to fix my motor after dropping a valve.

I bought second hand cylinder, head and piston but new rings.

There are 3 rings, the oil control is easy to identify, is there any difference between the top and second ring and can they fit either way up? A brief look at them when they arrived shows they are different colours which leads me to think they may have differences.

Thanks

In my experience with other engines as i havent had any with the 1200gs they will have "top"
etched on or have a dot which faces up. top and second rings are usually different.
 
From the service manual: Maybe the "oval section" will be obvious.

That's really helpful, thank you. I will have to look a little more closely when I get home and look for top marks and concaveness (is that a real word?)
