My rear shock blew the seal out this weekend. It dumped all of the oil out and made a huge mess. I just had the shock rebuilt and this was the first ride out on it. The re-builder informed me that the shaft had a nick in it and that it "might" not hold. So with that said- what other bikes share the same shock as a 2000 WR400? I am going to try to source one from eBay but need to know what years and models I can get a shock off of?
