    enduro CRF250R build

    I'm in the process of setting up my 04 250R for enduro and woods riding. I' had since 04 and used it for MX and play riding. Now I want to do more off road stuff. did the Mauna Kea 200 this past weekend and had a blast! 6000 - 9000 ft elevation high dessert type riding. This is what I have done recently to the bike to make ready. 07 OEM head w/ Hotcam stg1, SS valves, White Bros header mated to the stock muffler w/ spark arrestor. I had Race tech Gold valves installed a few years back and adjusted the valve stack to suit Offroad, geared done to 12/49. So far I like the way it performed, but need to work on suspension tuning to match different situations. I'm thinking about swapping out 1st and 3rd and 5th gear of the trans with the 250x gears, any thoughts?
