You mentioned it was hot as hell while running too.
If the cap, thermostat and fan are working, and you don't have the overflow hose on the wrong port, then it sounds like you have air in the system.
yeah I rode a buddy's 05 zx6r and it was running about the same.
when the coolant is full it runs way cooler but once it spits some out it runs warmer.
Pro caliber also said the air in the system I tried pumping the hose and went through a ton of coolant. Also I had them pressure flush it which would get rid of the air they said and it didn't help.
I think you're overlooking something rather simple. The cap.
That is why I asked the temperature, he mentioned he tested it but that doesn't mean it's not the problem.
If he is pushing fluid out at a relatively low temperature then the cap is suspect, I also considered a blown head gasket building up pressure in the system but discounted that theory when he said it's more prevalent after he turns the bike off ..

I missed that in the OP.
I wouldn't be surprised if that was the issue though.
if i shut it down at 200+ degrees. so at boiling temps already.
If the cap held more pressure than stock could it be possible that its just building to much pressure causing it to boil over? And a stock cap would allow that air to seep out of it rather than boil into the over flow?

I really appreciate all the help
thanks again!
The boiling point of water rises when coolant is added and it also rises under pressure.
You didn't really answer the question though, or I didn't ask it right. Does the bike boil over when it's running? What temperature is the bike running at?
If the bike isn't running hot and doesn't boil over when running then it is very likely you just need a new cap.

No it does not boil over while running. It typically runs 160-180 freeway even on cold days. And will hit 220 while at a stop light hot or cold days. But never boils.

I'll order a cap friday and will update.
That all sounds normal, the cap will probably fix your issue.
Make sure you top off the coolant level too, I like to simply rock the bike back and forth, side to side and squeeze the hoses to make sure there isn't any air in the system.
