I just got a used 2000 YZ426 last week and I can not wait for the spring. I wanted to post and see what I have to do to check out the engine, suspension, and all the other parts of the bike that might be problem areas. I do not know the history of the bike at all and my dirtbikes in the past have been all 2-strokes. I can do alot of work myself, I have turn a wrench or two. I just need some guidence on what to look for. Thanks and I look forward to hearing your posts.
