Found this gem of a quote from W. Tripp 10 years ago, going to try a few things before ripping the head off since there are NO other indicators of HG leaking. I have a suspicion it's the post-boiling he mentions, because every time it's left a puddle it's after I've flogged the crap out of the bike for like 10-20 minutes in the mountains and then parked it right away and turned it off. Makes sense she'd be incredibly hot, hot enough to post-boil the coolant given that during the 10-15 minutes its generally held at 10% ish throttle mid corner, run to redline for a gear or two throttling out of a corner, then back down and repeat.

Next time I'm in the mountains Ill flog it and let it idle for a few minutes when done playing to let the cooling system work as intended and see if it prevents the piss puddle.

I only hope it's not warped.


Symptoms:
Spitting coolant after being run (very) hard, wait till it cools, top up radiator, empty coolant overflow and next time it's run hard, it pukes coolant again.

Riding normally with a full power pull here and there is no issue, its when I'm wailing through mountains keeping the motor over 3000 RPM all the time that it pukes a bit of coolant when I turn the bike off.

Running great, pulls very hard, hard enough to pull up to 170 easily yesterday before I ran out of road, and generally is running perfect...except coolant puking more than normal. Plugs - dry, Oil - looks like oil not milky at all, Coolant - green and not chunky or anything, fan - working turns on at 97c.

I haven't heard much lately but it was common to have to replace the rad cap for just the symptoms you are mentioning.
