I'm about to sell my 97 XR400, I was planning to pick up the new Husky 450 but I don't want to wait and I might be limited in what I can do to it for the riding I plan to do. My previous bike was a 98 YZ400F. I loved that bike in many ways but the suspension was to harsh for tight trails and the motor needed a heavier flywheel for single tracks. But it handled great and the power was a blast. I have also ridden the new KTM MXC400, While a nice bike I didn;t think it was worth the extra cash and my YZ was faster and handled better. The new CRF450 was pretty amazing but not set up well for off-road riding. So I'm thinking of a 02 WR426: for both medium to tight off road (fire trails. single track)and some desert riding (baja, Mojovie). What is the ideal set up? I'm thinking a larger YZ 3.2 gal. tank / seat, better bars, But I also think a 10/12oz. flywheel is in order. Will this combo work with the YZ cam timing? or is that counter productive? Thanks for any input.
