Going to be getting my hands on a 07 yz250f for a great price. I race moto and desert and have always been a two stroke guy, this is my first four stroke. Owned a drz400 before but that is all the experience I have with a thumper so I have a few questions. The bike looks like it was an ex race bike. It has lots of aftermarket stuff on it and looks like she's got 100+ hours on her at least. The head was supposedly redone recently..... I am a person that like to ride the same bike for years, my last bike was a 99 rm250 that I had for 6-7 years. I'd like to do the same with this thing! So, what should I do to make sure she lasts a good long time? I plan on riding it a couple times to "feel" her out before I do anything. Any and all tips and tricks are welcome! I'm excited about my foray into the 4 stroke world!
