I'm trying to get the rear wheel off my '99 TTR-250. I removed the cotter pin and axel nut, and the manual says the axel should slide out. Wrong! Me and a buddy even tried coaxing it along with a hammer and a wooden block, but it doesn't to budge. So, I removed the chain and tried to slide the whole assembly out the rear - then noticed I would have to tear the brake assembly apart. Anybody have any experience with this?
