Air Bleeding. Help!

Well my E series motor is all together in the chassis with new cylinder and top end kit. I was following the instructions in the manual to bleed the air from the coolant system, and it says to loosing the air bleeder built on top of the cylinder head. I did this and no air nor coolant was forced out. If I squeeze any of the coolent lines then antifreeze will come out of the bleed, but it's not flowing out on it's own. Is this a problem? Or did I luck out and didn't have any air in my system? I poured the coolent in slowly and waited about 30 seconds, air came our of the fill spout on the radiator. I then filled it back up after it dropped. Waited another 30 seconds and nothing happened, so I'm assuming the coolant was completely settled. Any help would be greatly appreciated. Thanx.

What yyou have desribed sounds about right.
Start it up and run it for a bit and take a look in radiator. You should be fine.

Ok. I checked the radiator after it cooled down and all is good. It didnt seem to be over heating. I let it run for a good 10 mins. I just wasn't sure because it doesn't mention anything like this in the manual. Thanx

yeah whenever you take the radiator cap off coolant should flow out of the bleeder screw, it had me confused the 1st time I tried it. Also be sure to fill up the other radiator if you havn't already

10 years of riding the KDX never once bled to cooling system YMMV

Was the radiator cap on when you removed the bleed screw?
The cap has to be off, or the coolant won't flow out due to vacuum- gotta get air in there to displace the coolant coming out.

!0 years and never bled the system.. Have you ever serviced the system, other than pop the cap once in awhile?
Remind me to never buy a used bike from you.. :wink:

Yes the cap was on. It says to put the cap on in the manual. Weird ehh? I'll bleed it again with the cap off just to be safe

Better check your muffler bearing while you are at it
