I have checked out a cooling system pressure tester and used it with very good success on finding coolant leaks. Get every off the bike so you can see connections. Then pump up pressure to about 15-16 psi and wait. Leaks will eventually show up in places that you did not know existed. That's how I found some of the water pipe 'o' rings were bad on my 1st 1500 wing. I have also done this on 1 of the 1100's I owned also. Was the only way I could find the leaks. Now I have another 1100 for a pet project and see it is leaking. Once our weather breaks and I can get it into my shop, that's what will be done on that one. Good luck and keep us posted as to what you find.
