I am considering trading my 2008 crf 150rb for a 2006 crf 250r with a long list of mods. I was doing my research and saw that the 06's had valve issues. But you can google just about any bike and find people saying they have a ton of problems with them. Im trying to get the opinions of people who have actually owned or had experience with this bike. It looks badass I would love to own it. I just dont want to get a bike that's gonna be a headache.
