Message: [QUOTE="jbag, post: 1256105, member: 83411"] I've searched. '84 XR250R Bike is all original and smoked pretty bad (I'm the 2nd owner). I finally tore it down and mic'd everything. New std. piston and rings going back in. Which is the compression ring and which is the 2nd (scraper)ring? 1 is a shiny brass/copper color and the other is black/gray like the 2 lil' one's on either side of the oil ring. I'm assuming the shinier one is the top comp. ring? But...NEVER ASSUME!!! Thanks in advance, jonny [/QUOTE]
