i just purchased a 2008 wr450 after coming off a 2004 wr250. i took it out the other day for it's break in ride. did the 5 heat cycles as recommended by my dealer with constant accel and decel but not revving too high. the gas was topped off by me and only got 74 km's on it and it quit. was out of gas and needed the reserve to go the last 3 km's to the truck. now, coming off the 250 which i believe had the same 8 litre tank and a much further range of well over 100 km's and higher revs does this seem normal for the 450 or is it going to improve dramatically with more km's?
