Hey guys , it's been a while since I've been on and I need some advice . I went riding the other day and noticed that after a few hillclimbs my bike was hot and I could hear the water boiling . I went back to camp and it was very low . I let her cool off , added some water and went out again , same problem . Is there a simple way to pressure check for leaks ? There were no visible leaks that I could find . Anyhelp would be appreciated .
