I always get confused by this. I have posted before and received answers, but am still confused a bit and have a couple questions... 1. In general, should all fork seals for my '06 CRF450R be the same? And what I mean by "be the same" is...should they all generally look the same? 2. Assume I order a fork seal replacement set for my bike. The set arrives with no written instructions and there's nothing on the seal to help a noob understand which side of the seal goes toward the wheel and which side of the seal goes toward the oil. Is there a foolproof way, that would apply to just about any manufacturers seal (just by looking at the seal) to determine which side goes which direction?
