I was recently doing some engine maintenance on my '97 wr 250, and the bike sat on the stand for about 2 weeks with the rear wheel off the ground. After finishing the work, I went to :( test ride the bike and noticed that the rear shock was bottoming and didn't seem to rebound fully. I haven't noticed any oil leaks and I checked the nitrogen pressure. Still about 160#. I had the suspension dialed in nicely for me, now the rear just seems dead. Any help would be apreciated.
