Coolant leak, help identify the culprit

Hey,
Just got done working and noticed a coolant leak. (again)

I already tightened up the obvious clamps, so this time I just let it idle after coming home and looked for signs of leak.

It appears to be leaking from a screw on top of the front cylinder marked in the pictures. What screw is that ( check manual, but with no luck) and how do I tighten / fix it.
Sturgis is approaching fast and I need the bike to be ready for the long haul.

Thanks for inputs
(clamps are tight and checked, and it's not leaking from the waterpump)

Located the screw.
Number 7 in the picture: fastener and washer.
Does not appear to have a reason to leak. Anybody know if it could be possible to leak from there, or is this just an blind attachment spot on the cylinder?
Not sure where it's coming from, if not from there.

If leak looks like its coming from there Id check the clamp that is attached to that bolt didnt rub a hole in the hose there.

Yup. That was it. I took the airbox off. Then removed said clamp and found the clamp had actually cut into the pipe that's there. After starting up for a second I found the leak right there. Guess I have to order that pipe new. Hopefully the install/ removal won't be a nightmare.

Coolant pipe is on order, takes 2-3 weeks. Shipping to Canada really sucks. For the time being I'm patching up the damaged pipe with this. Hope it holds up.

Greets, just had SAME thing happen. Pitch that "P" clamp. Also make sure to order new heat shrink clamp too. You'll need it. Also that steel putty stuff will work. Used while on my way to Laconia this year...pure magic. I also covered that temp fix with heater hose and a hose clamp.

Also hardest part was removing the battery plate....FYI

And you'll need a badass heatgun.


Stay Frosty...

I'm around 11000 miles.
Thanks for the tips.

I did order the heat shrink clamp as well as the pipe. Also ordered the rear breather tube while I was at it.

When you say 'pitch the clamp', did you mean you are riding without it ?

Just noticed I have a leak as well...My bike is an 04 VRSCA with just over 5200 miles on it...Believe one of the shrink clamps is the culprit. Do these have to be replaced or can you use a heat gun and reshrink and/or shrink them further if they have loosened? Guess what I'm saying is maybe they weren't properly shrinked when installed...then again the bike is 8 years old.

dam i just had mine off and i didn't see a scuff mark or any thing showing ware. it might not be the clamp. it could be an erosion problem from the inside. could you check the culprit and see if it is thinner than the rest of the pipe??? although it doesn't compute since mine has 33,000 miles on it.

mine leaked a few years ago and all i did was install a hose clamp on it. its been that way for 5 years now and not a drop.

too much of a pain in the butt to take everything out and replace just the heat shrink clamp (gates clamp as its called)

So...does anyone know if you can get the heat shrink clam tighter by using a heat gun on it or do I need to try and replace it? I can always go with a regular clamp I guess...
