Hi everyone. I'm new to thumper talk and find it quite interesting. Alright here's my problem. I took the swing arm off my 02 KX250 to check and lube bearings, seals,etc. The swing arm came off great no problems there. All the parts look great and I lubed and put everything back together the way they came off. Even checked the manual to verify. Here's the funny part. The swing arm will not slide back into place. It only seems to off by a fraction but that fraction is killing me. I've taken the swing arms off of Hondas and Yamahas with no problems getting them back on. If any of you gear heads or super wrenches have any suggestions I'm all ears.
