I have a light ticking noise at Idle that I don't remember my WR400 having. I just got through lapping the valves, putting in new rings, and adjusting the valves ( I checked them like 4 times over to make sure they're good). It idles perrrfect and starts like new - when cold and warm. And it has great power too.

What is it... anybody? :naughty:

Just wondering if it's a sign from the moto devil. :D

Thanks :naughty:

After 2500 tight trail miles, my '98 WR400 needed a big end rod bearing replacement. Take your flywheel cover off, and rotate the flywheel back and forth by hand and see if you can feel any play. I could feel the play in mine.
