I have a 2001 yz 125 and I like it a lot. But I struggle on long hill climbs and technical rocky areas. I got an offer for a 2004 yz 250... Here is the cl ad http://pittsburgh.craigslist.org/mcy/5237791515.html he says that there is a weird sound in second gear but the entire bike was basically rebuilt. I'm wondering if I should take it. He wants me to throw in 200 bucks for it...
