Hi, I am looking at a 2000 Foreman 450 with 1400 miles on it, 1" lift, 27" MudBug tires. It has a new tie rods and bearings, and is in pretty good shape... except for this sound, check out the attached clip that was converted for Youtube by Psychobob on another forum. (thanks again!)

I held the like on the right side of the engine, then moved to the front, about 2 inches away. The machine has good power, doesn't burn oil, and just had the valves done according to the prev owner.

Any thoughts? I am hoping nothing worse than timing chain, but...

Thanks for your help, great forum!

I don't think that is a timing chain. I think someone did a valve adjustment and did not tighten the lock nut on the adjuster screw and the screw backed out. Myself I would never buy a quad with the accesories you mentioned. You know it has spent a lot of time under water. I predict it will turn into an endless money pit.
