Hey guys i just got a 2007 KX250F (might i say is a nice upgrade from a rm125) and i have done a little bit of reading on the 2008 model but cannot find much on the 2007. in my reading i found that the 08 had some overheating issues and needed an aftermarket waterpump. i also saw that the 08 had a power lag topend of 2nd shifting into 3rd so a lot of people were putting a one tooth larger rear to compensate. i guess my question would be if the 07 would have these same problems since they didn't change much between the 07 and 08? any help or advice on upgrades everyone has used would be helpful too. Thanx
