Mysterious Coolant Leak....
Hey fellas. just busted out the 03 from her winter sleep and so far so good. I wanted to do a good old fashioned coolant flush, and that's where the weirdness began. I drained the old coolant out, the ran just plain water through the system. Then I drained that out and added Blue Devil radiator flush and some more water to top it off. Ran the engine to purge any air, then topped it off with more water. I Then took her for stroll around the block just to run that stuff through the system and then put the bike away for the night.
I was in my garage the other day doing something else, and I heard a periodic venting sound coming from the bike. I notice a small drip coming from from the hose connection that enters the bottom of the cyclinder. the Leak would increase whenever the coolant system would go through one of those periodic venting cycles. So I went ahead popped the radiant cap off and there was a rush of air out of the top of the radiator as the coolant system decompressed and splashed coolant everywhere. The bike wasn't hot at all, not really sure what the heck was going on there. I topped the radiator off and then checked it the next day and it did the same exact thing.... not sure what tis going on here. It appear my radiator is leaking now too and when it wasn't before. Not sure if it cracked under pressure or something.
It appears the coolant system is not decompressing properly after the bike is ridden. Im not so concerned about the leaking radiator but more about my entire coolant system itself.
