part numbers for timing chains?
I'm researching timing chains.
Pro-X seems to be quality. I found one with part number 31.1323 listed as 83-87 XR and XL600's on ebay. However,
It may be NOS as the Pro-X catalog has no listing. Anyone know if this is the right chain? Any other chain part numbers for this bike? I really don't want to spend even more money buying the later chain and sprockets...
Anyone know the D.I.D. part number? how about the Wiseco? Any other brands I'm forgetting?
