My brother just purchased a '98 WR400 and I'm trying to help him out with some info. I don't ride the same bike so I'm not familiar with all of the little things you can/should do to this bike for improved performance. I don't frequent thumpertalk too often but I seem to remember there being an archived section of articles and "how-to" types of info before the site received an overhaul a few months ago. Does this information still exist somewhere? I'm looking for info on the common things done to this bike such as changing the timing specs, grey wire, exhaust, throttle limiters, etc. (I apologize if I got any of those wrong....like I said, I'm not real familiar with the bike). I'm pretty sure all of this has been done on the bike, but he's try to educate himself on the topics. When he bought the bike I told him to come here because there was a bunch of info on it, but when he did he couldn't find it. Am I up in the night with this.....does anybody know what I'm talking about? I'm sure these topics have been discussed to death so there's got to be some good archived info somewhere. Can anybody help? Thanks in advance.
