Joy of Joys, look what I get to do!

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 would think if you had a leaking head gasket, it would be puking during the flogging period and not after. I always baby my bike the last couple of miles before I put her away. Do the same with my car if driving hard. Like the wife- never let her go to sleep riled up. ALWAYS allow her to cool down first or you'll regret it the next morning!
 
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.
Rob, unless I missed it, where is the coolant coming from.

+ 1 rad cap, had the same problem with my Roadster,

BTW T1151150 is the old type head gasket, T1150189 is the newer one
 
mine puked some out of the overflow tank after a hard work out on the second time i just did not add any more and all is well.
i think it is good info to take it easy or let it idle for a while before turning off. my fan setting i set it down so it would come on sooner and also set up the wiring so i can turn it on when i want.
i would make sure that it is coming on.
good luck
