Normal stuff like exessive engine noise, water in tranmission fluid, wheel bearing head stock bearings
depending on the year check for damage on the radiator and casing, ( on the newer model 2007 to 2010)
put bike on a track stand so both wheels are off the ground, now lift up the back wheel there should be no play in the linkage if th re is more than 2 inch you may have to replace any number of the many bushs etc in the linkage but not a big problem. water leaking through water pump casing I understand is any issue with the pre pro years.
I have just brought a 04 250 pro and it is a fantastic bike.
Im sure there is more knowledge in the forum but this is what I was told to look for
