Thanks for having the CRF250L on your to-do-list. As a bit of info, there are two possibilities for rack mounting. One is to use 4 8mm bolts that go vertically thru the rear fender and get the rear subframe....some would argue this would be a better way to feed the vertical weight of the rack etc into the subframe than the 4 bolts that come with 2 long bolts for bungies that hold the seat, and 2 stick out from the sides of the fender...which take weight on the bolts in single shear. pick your poison I guess. The WR250R Yamaha, and the 2006 Husky 610 had those bolts going vertically into the subframe.
