Coolant leak - seems only to leak when motor is cooling down -- Doesnt leak a lot - Leak seems to be coming from the front of the engine . Checked the heads - nothing visible.
I get a few spots on the floor -- Once the engine is cool -- it no longer leaks. Seems to be from the front rhs of the lower portion of the engine -- I cant quite pinpoint the source ??. 2001 Royal star tour Deluxe
Whenever I have a water leak problem I fix it the way anold mechanic taught me. I go to the drug store and get a bottle of sodium silocate. I drain out my coolant and save that. Then poor in the whole bottle of SS and top it off with distilled water.Then I run the engine until it's up to max temp. Shut it off and let it cool over night. I drain it and replace the coolant. Problem solved. SS will seal all leaks and hold up to high temps. I have fixed broken headgaskets many times and even a cracked block once. So there you have it, a true old school fix. Works for me. Hopefully it will for you.
If you top up the water before each ride,this may be it.The water expands when it's getting warm/hot.Once you pull up,the motor gets a lot hotter.No air across the motor/radiator.This causes a bit more to expand past the radiator pressure release.The radiator cap.Its normal.Beside the rad. cap is a thin hose.That is probably the source of the waterHope this is your problem and hope it helps

Regarding the coolant leak in my 2001 Royal Star -- I did a little more looking and finally pin pointed the source of the leak.. Here goes.. I removed the cooling fins from the cylinders -- there is a rubber plug with a threaded metal center located near the bottom bolt hole . There is a small leak from this plug during the motor cooling phase . Hot or cold the motor doesn't leak -- just in the transition period while cooling down . just wondering if it is much of a job to change this plug out - or can it be tightened somehow??
