Hello! Without boring you to death with a bunch of details, I may be getting a sweet deal on an '06 450. WR is a better choice for my riding, but the deal is on a YZ. Are there things I can do to make it a friendly machine for everything from light MX duty to tight singletrack to putting with the kids? I currently have an '02 XR400 that I like, but I feel it needs less weight and more suspension. I wouldn't mind more power... Improved cool factor is nice too. I heard from someone that the gearing will be bad for the tight stuff, but maybe that was for the 4spd tranny. Maybe the 5spd has cured this issue. I also heard she'll spit coolant if I idle it too much. I've heard something about a water bottle mod as a coolant resivoir, and possibly a 14t front sprocket for better woods gearing. Can you guys verify or debunk this? Any other modifications? Honestly, if I bought a WR, I would want to remove the lights and the starter (battery, coil) and stuff anyway. If I can kick start an XR400, I can kick a YZ450... I think. Thanks for any help you can provide! Oh, yeah... The search function was down, so my apologies if there is another thread on this. A link would be great. Thanks again.
