I am having some jetting issues right now so maybe thats a small part.
The bike sits in my clean garage so I know its not leaking anywhere that I can find. I thought that maybe there is some debris in there that is clgging it somehow?? Just not sure

1 A damage in the radiator cap: it's possible a failure in a one of the two seals, so the cap can't mantain the correct pressure in the coolant system and water get out. You can check this adding a water tank at the end of the tube from the right radiator and to control if there are some leaks.
2 It's possible the failure of the head gasket; if there is this problem there is a lot of smoke exaust too, a white smoke. But this kind of problems in the up-to-date bikes is very difficult.
3 It's still possible, but very difficult, a porous, very little hole in the the head or in the cylinder. In this case it's possible adgjust the problem with a specific product without change the head or cylinder

I will go back to stock jetting and proper anti-freeze and see if this solves the problem, if not I will start checking other things as mentioned in these threads.
Thanks all for help

-It's a weep hole. If the seal goes bad you will start to "weep" fluid out of it.
There is a predrilled hole there for some reason.

He also said that typical radiator fluid is not thin enough to run properly through the bike.
Yes usually it's like this, but it's possible the contrary; it's very, very, very, very, very difficult, but it's possible

my 03-wr450 also leaks while kiking on a cold start out of the weep hole but quits after it starts the dealer said it was nothing to worry about?
I don't know... It's possible that when engine became hot after the first minutes after start the house pump dilatations quits leaks.
You have to control water level in the radiator: these kind of seals fail quickly, so you can check the problem before that it becames dangerous for you engine

You may need to do a cooling system pressure test the special tool needed is sold at sears(cooling system pressure tester).
I have looked at them in sears but did't remember if they came with the "small" radiator cap adapter for japanese vehicles.
Take your rad. cap with you to make sure this tool will work.
The only thing I didn't like about the sears tool was it was made out of plastic---Snap-on or Mac tools makes metal ones that I know come with the "small" rad. cap adapter.
