Bought my 06 XR brand new in late 05 when they first came out. I love the bike but it's still stock and underpowered. I'm building It as an expidition bike, not a race bike, to match up with my expiditioning built Jeep Wrangler. Even though I've had it for a year I haven't done nuttin with it yet it's just sat there till now. I've pulled it out and am begining to go through it. I've heard of a restricter plate in the carb and the exhaust has to go. Tires are Dunlops 50/50's ,not sure the specific tire don't have it in front of me right now, But turning with em sucks off road. It's been suggested to me to put a more aggressive tire on the front than the rear. Keeping in mind this bike will see just as much highway time as offroad time. The only other thing is the gearing. 1st to 2nd is a big jump kinda scary when off road so I'm lookin to do some'n about it. I'd love to see other XRL's and hear any suggestions. See ya'll out on the roads n trails real soon. Once I take some pics i'll post 'em and the mod's as i go. 1st will be a sissy bar to accomadate camping and long travel gear. Gonna build it my self i'm an accomplished welder and half ass decent fabricator considering some of the tools i don't have yet.
