2006 zx1000, can't keep it cool...?

Having all the fittings low will help but you're not going to completely solve your problem until your filler cap is the highest point in the system. With the fittings lower, but your filler cap still there, there will still be a noticeable amount of air in the radiator.

The best solution I see is to put a hose filler in the hose at the highest point. No need to change anything else.

You could take rad loose and tip it to birp air from that top hose, but probably still have some and would likely come back.

Thats the ticket man and a cheap fix

Where are you running it? Desert or snow will make a difference. Also, does it get hotter when you drive it hard vs idle for 10 mins

Also it might help to remove the bottle-neck in pic two coming out of the engine. It looks like you reduced the diameter of the hose there? This makes the pump struggle and cuts the gph down.

^I didn't even notice that, but it's hard to see exactly what's going on there. If it's reduced from the block side then yeah that definitely needs to go.
