The best mod will be replacing the exhaust cam with the 03 YZ450F
with autodecompression about $150.00 and remove the baffle if you
cannot afford a after market exhaust.

bin and they went to the autodecompression cam in 03 if you use the YZ it does
a real nice job increasing low to mid range with any loss on top, also you will get a
lot quicker throttle responce.

My Brother has an 01 wr250. We baisically do the same stuff to both bikes (tear down, and mod them together).
Would it be possible to run a yz250f cam in an 01 wr250f also?
