I'm finishing up a top end rebuild on a 2001 KDX200.
I've refilled radiator and overflow bottle the coolant, then loosened and removed the bleeder screw on the top of the engine, but I didn't see any coolant run out of it.
I haven't started the bike yet.
Does the bike have to be run before I'd see any coolant run out of the bleeder screw?
Thanks for the help. This has been a quite a project for me.

Are you doing it with the cap off the radiator?

I was thinking along the same lines. I can't remember 100%, but I'm pretty sure it should bleed right out of that hole.

Re: top end rebuild - coolant refill question
You may not see coolant run out of that screw hole, its a high point drain for the cylinder to make sure there's not a big air bubble that could cavitate the pump. I usually open it, kick the bike over without starting it a bunch of times, then put the screw on. Then leave the cap off the radiator and start and run the bike till it quits bubbling. Helps to squeeze the hoses and stuff to move any trapped air.

Thank you, Bufftester. I'll give the kick starter a try and see what happens.bufftester wrote:You may not see coolant run out of that screw hole, its a high point drain for the cylinder to make sure there's not a big air bubble that could cavitate the pump.

I appreciate your help, and everyone else's help with all my questions on this project.
I've learned a lot, and can't wait to get the bike running again.

I think that was the problem.thirdgenlxi wrote:Are you doing it with the cap off the radiator?
I did what Bufftester suggested and removed the bleed screw, then kicked it over about 15 times.
Didn't see any coolant coming out of the bleeder.
Decided to open the radiator cap, and it shot coolant about 2 feet in the air out of the bleeder screw.
So I learned something the hard way (again)

Great, you'll have that thing back together in time for the Desert 100!

Where is this bleeder screw on the motor?

Its on top of the coolant nipple coming out of the cylinder head. There is a clocking plate for the coolant nipple in this photo, but this is the bleeder screw referred to above:
