Hello Folks, So few weeks ago I got my first dirtbike, '99 YZ250. Long story short seemed like a good buy, so I picked it up, but after starting it at home I noticed it had a leak. It's coming from one of the seals, near by the exhaust area. Since I'm new to this whole dirtbike experience, I'm not sure if this is something I should take to a mechanic or attempt to fix it my self. I've been a street bike rider for a while and worked on those but never on a dirtbike. Do you guys know any reliable mechanics in the Portland area that I could go to? What should I expect to pay for such a job? Any other tips would be greatly appreciated. I can't go riding until I figure this out, and I really want to try this new sport Thanks guys!
