Ok guys, starting a new thread here. I'm starting work on my '83 xr200r again. Going to turn it into my practice bike. It runs great, engine runs good, no issues with the carb or anything. However the suspension seems a little tired. I've noticed that whenever I sit on it, it usually sits kinda low. Also if I'm riding and I hit a small bump or dip in the road, I can hear some sort of clanking, I think it's bottoming out. It feels like the rear shock/spring is too soft or weak. I've already rebuilt the forks once, and they seem ok. Only question I've got for the forks is am I supposed to add air in these forks or are the little valves for bleeding air? I've heard both so I'm a confused. I consider myself a bigger rider, I weigh 215 and am 6'5". Am I just too big for the bike? Thanks guys.
