Air in the Coolant System!! How do I fix that.
Ok so as the title says, I've got air in my f'in coolant system cause when I stop the bike the radiator spits a little bit of coolant from the pressure relief tunnel toward the top of the radiator. So I need to know how to get the air out of my system.
Is it like cars where you put the car on an upward slope hill so the radiator cap is the highest point of the system, then run it with the cap off so when the thermosat opens all the air will bubble up to the top, then simply refill as it bubbles. Turn off the vehicle fill if needed and put the cap back on.
Or is there a different method for bikes?
Once again thank you to all the help.

I suppose with a bike, you could just lift up the front end a few feet. Just make sure you aren't going to starve it of oil.

When changing your coolant, did you bleed the system by turning on the bike, letting it warm up, then revving it a bit, all while the rad cap was off? That should have been sufficient.

Yup, I assume you dont have a manual for your bike so here goes..
After you fill the system up, remove the reserve tank cap and fill it to the upper line.
Shift trans into N, let idle 2-3 min.
Snap throttle 3-4 times to bleed air from system. (I just yanked it wide open for a split second, maybe hit 6-7k)
Stop engine and top off coolant in radiator, put cap on.
Check level in the reserve tank and fill if neccesary, put lid on.
Thats it.
