Hey guys, I bought a used '07 RM-Z 250. Is there any way to tell how many hours are on the bike. It's in pretty much mint condition but I want to know what I should check before riding it. The guy who sold it said his son used to ride it before he moved out and he didn't know how many hours were on the bike. I did the obvious oil/oil filter/air filter changes. I hear repairs on 4-strokes can be quite expensive so I just wanted to ask around to see what kind of preventative maintenance can be done to ensure a couple years of hassle free riding. I downloaded an electronic service manual so if anyone needs it, just send me a message and I'll email it to you. Thanks!
