At one of the cylinder studs, on the left side. The one just to the rear of centerline. Probably has a number...I don't know what it is.
Mine seeps some. It's just under the head hose..and it's not the hose that's dripping.
Just curious how common it is.
Anyone else? It's a fairly new event. Last assembled with a new head gasket w/Permatex copper coat.

CC... why did you use the permatex? Mine went together dry... perfect seal.

I have heard something interesting from two different sources concerning coolant leaks. One source is a guy with 30+ years as an auto mechanic and another, one of the local Saturday morning question and answer talk radio shows. Both said the same, "Some small seeps and drips can be cured by making sure you have no more than 50% antifreeze in your system".
Might be an easy fix. But, do ya really think it could be that simple?

Why copper coat? Considered it extra 'insurance' against possible leaks, natch. Evidently an error in consideration, 'eh? First time I've used it. I thought maybe the bumped static compression could use the favor.
The pinging I've had since the port job (when I've not run Trick114) sure could've put the hurts on the cylinder/head seal.
Antifreeze is pretty slippery. I am using a 50% mix. No reason to, actually. It rarely gets that cold around here. Force of habit I guess.
It's not a huge thing. Has only seeped a bit prior to last night when I noticed it had leaked enough to form a dribble down the cylinder. But...I took the cap off the check the fluid and got a pretty good spit of air out of the pressure cap, so it's been under pressure just sitting there. Yes...it should've been a vacuum hiss..but it didn't sound like it and the coolant was coming OUT at the cylinder stud.
Someone is going to ask if I'm losing fluid. The simple answer is yes, but there is at least one other reason for some of that. It was pointed out to me (by a real cutie btw, but that's not relevant) that I was missing my res cap. Don't know how long it had been missing, but that is part of the reason I'd been low on coolant after a ride....which I have been a couple of times. Maybe 1/2 cup or so.
It's seeing the dribble that bugs me. Can't be havin' no trouble considering the upcoming weekend State of Jefferson Ride!! I'm not anal about keeping my bike spit-shine clean (ha..that's funny!)..but I don't want to be making a bigger mess than necessary!
I consider myself fortunate that Ski and FarmerJ will even consider being seen in my general vicinity! Last I saw Ski's bike it looked like it had just come off the showroom floor.
My bike looks like it's been ridden....pretty hard AND put away wet to boot!
Oh..the 'hard' part not relating to expert use and on-the-edge riding...more like hitting hard things (mother earth) with parts that aren't supposed to (pipe, fenders, helmet and such)! YeeHAw!!

I would not think the spray on copper coat would have hurt sealing. I normally follow manual protocols pretty close unless I reusing a gasket then I'll use a spray on sealer or a fine smear of silicone sealant as deemed prudent by me..

CC;
Is the leak right at the nut holding the head on or at the gasket between the head and the barrel? I assume you check the torque on the head and barrel occasionally?
If it's the gasket and you don't have a spare, I've been told that the stock gasket can be re-used by cleaning the RTV film off it, apply a thin coat of silver spray paint to the gasket, then install while the paint is still slightly tacky. Also the copper coat should do the same. I've not heard of anyone applying copper coat or anything else for that matter over the RTV film that is on a stock, new gasket. It might be that it had a bad reaction and is causing your problem.
Don't let this cancel the ride now!!
I suspect that if you were down 3 to 4 oz. of fluid (half a cup), the bike might have been running hotter than normal. This could have affected the torque on the nuts. Also, maybe your radiator cap is bad and isn't releasing fluid to the overflow at the correct pressure. That might allow too much pressure in the system and it found a way to release at the nut you mention.
