I replaced my fork seals Friday before the race weekend, and I'm pretty sure I should have changed the bushings, too. The manual said if any bronze/copper color shows they should be replaced. All 4 had some color coming through. It was tough to get the one leg apart even, and one bushing had a small ridge on the outside. I stupidly didn't have the parts (I didn't think they'd need replacing on a 3 month old bike, AND I had no idea how cheap they were). Bad bushings will make it stiff, right? (I did search this topic). Forks definitely felt stiff this weekend. Will it damage anything else using bad bushings? And finally, can I re-use the fork seals/wipers since only 1 race? Edit: It's on an 07 CRF450R if that matters.
