Blown head gasket?

Reassembled the scoot today, gassed and fired it up, first time since the chopping started.
Rear cylinder, top bolt, not drain plug
Short clip
WTF

What dose reassembled mean??? It looks like you did something wrong....... We need WAY more info on what you did and didn't do.....

yeah, sorry fedex showed up... more parts

chopping frame, seat etc, didn't touch the engine.
I DID however clip the radiator line from along the carb to the top left side of radiator. Unless I misunderstood one of those tjcustom vids, that line was for warming air to the carb not needed
like I said, was running before project bob started
I'm utterly flummoxed

When you clipped the radiator line to the carb did you plug it off???

Good luck with chopping a water cooled bike..... It's tough but it can be done...

[Guest]

Yup, clipped it, and its vacuum counterpart, as well as that radiator stub. Those weren't leaking.

Dragged bike out, back flushed system... flushed out that funky floating thermostat housing wtf

thanks, credit goes to you actually. What you said about chopping the water cool is what did it, I've desmogged other bikes, approached it exactly like that-chopping the emissions nonsense.
Fuck I'm smart.

Went back out and stared at it, fired it up, figured out which way the cooling system flows thru the carb (dam youtube, yeah, cut this, no worries) and studied it a bit.
I chopped the ENTIRE coolant from head thru carb, back to radiator. A total of about two feet of line, the section that heats up the carb and its return. Less lines, a tad bit cleaner on that path to bobbed.

VERY low pressure thru the lines into the carb, but once it heats up, ESPECIALLY that pressure in the system right before the Tstat opens, the return line fitting to the rad heats, expands and weeps.
And again when you shut it off, the heat sink cause the systems not circulating

then, the path took it down the fins (behind wires, lines) to the inside upper edge of that bolt, making it LOOK like it was pouring out that bolt (and suspect head gasket)
Whew. Was really pissing thinking it was the head gasket took a shit coincidently....happens on old bikes when you start fucking around, eh?

Not a problem.

It is not a blown head gasket.

But you cannot compress a fluid either.
Are you just stopping up all of the coolant?

Not at all.
I bypassed that nonsense where the carb is heated with the radiator to decrease emissions, control "icing" and shorten the warm up time, thereby reducing emissions.
That entirety was added..I think in the late 90's? Started in Cali, headed East eventually.

I've got bikes for touring, cold days, rain etc, THIS is going to be go to my intown, hop around go to work bobber. The possibility of icing is nil.
The coolant still circulates the block, that equalizing crossover pipe, as well as kept the overflow reservoir etc etc

[Tattooo]

Not a problem.

Not if it has water in it..... I didn't know that's why I asked the question....

[DustyDave]

If'm memory serves the water flow was regulated so a little dripping just means that the thermo valve is working and you need to plug the pipe off.
