Today I found my coolant leak.
I pulled the fuel tank and the air-box but there wasn't much evidence of a leak. I did see a small purple tell-tale "dry" stain (has purple engine ice in it) but absolutely nothing wet and no puddles. so to be sure I took a vacuum/pressure hand pump I have for doing brakes and leak down in 2 strokes, and attached it to the overflow stem on the right side Radiator.
My suspicion was the short 2" hose the connects the front head to the thermostat.
As you know, there is a 2 way valve/spring in a Rad cap, it compresses at a certain pressure to allow coolant out and into the overflow tank when hot, and allows the coolant to return as it cools...so....just attach the pup to the overflow barb on the rad and pump unto 15lbs on the gage. (dont go too high), and wait.
In less than 2 minutes it started to drip, right were I expected. the hose clamp wasn't tight, so I snugged it up a wee bit. we will check it again later when I have time. if not ill have to replace the hose which looks to be a huge PITA.
