I just picked up a stock/uncorked 03 wr450 just wondering what other riders get for miles to a tank of gas and top mph, my gps said 83.6mph!!!! I think it stock gearing but not sure, and I have 52 miles to my first tank including flipping to reserve, I have not run out yet but plan to ride it till it quits to see what it can get. it also seems reaaaaaaallllllllllyyyyyyy cold blooded is that common? oh it has been jetted... ps it will become a snowbike this winter!!
