its not a big problem, but it does happen unfortunately! The yz400/426 tanks are really bad, some people have been through 2-3! Its a shame since i wanted to give my bike the newer look! i have read a lot that the 02 YZ250 frame is very stiff and makes for poorer handling and suspension setup compared to the 01. I wonder if this played any part in McGraths difficulties since he did comment about his setup and since he is such a precise rider this may have effected him more than others! Maybe if they could have dressed the 01 frame up to look like an 02 (like honda did with the 93 cr250) then he wouldnt be looking for other rides this year!
