I have discovered a cylinder head crack somewhere in my #6 spark plug hole in my 2000 GL1500C.  An orange liquid is coming out of the hole after running for a while.  It is not oily and cleans up like powder.  Is there some product that can repair a what appears to be a small crack or do I have to get a new cylinder head?  I would attach a photo but I don't know how to include the photo with this message.  I only have 19,000 miles and the bike has been meticulously maintained.   Thank you.

Here is a couple things to try. Clean the area where you think the leak is coming from, ride the bike for a good distance and re-inspect. Don't see this as being sarcastic, but an orange liquid that cleans up like powder isn't liquid, maybe rust.With the Valkyrie engine that has 19K miles and meticulously maintained, there shouldn't be a cracked head. The other questioned is, is it stored in a garage. If the plug boots leak a little water into the plug area it should drain out thru the weep hole, it not water may cause it to rust a little.

If you have some pictures send them to me and I'll post them for you. It's easy once you learn how.

I think you may have a blocked drain hole. On the underside of the head just next to where each exhaust header bolts on, you will see a small hole, one for each cylinder. This is a drain hole from the spark plug reseptacle in the top side of the head. Get a piece of wire and poke it through the drain hole to make sure its clear.

Good luck! I hope that's all it is.

Thank everyone for the rapid response.  I sure hope it is a clogged drain hole.  The bike is garaged and kept immaculate.  I can't imagine the extent of the ooze coming from a clogged drain hole but very hopeful.  I am going to send the photo to John Schmidt as he has so kindly offered to post it.  It looks pretty bad.  Thanks again.  Woodeneye

Looks to me like he has a plugged up drain hole. Don't remove that spark plug until it's all cleaned up. Sure don't need that junk in the cylinder.

Thank you John, 8Track, Red Diamond and all.  Thank you John for posting the photo and your opinion.  I have already cleaned the spark plug hole very carefully without getting anything in the spark plug hole and will check out the drain hole and take a ride.  I can only hope that when washing the bike I got a lot of water in the hole and it rusted and when heated blew out to the mess you see.  I will let you know how it turns out.  Woodeneye.

Can't really tell from the pic, but it looks like the front of that plug wire boot is NOT fully in da hole.

I had that happen to me and I rode in 7 days of rain going out West & back one year.   Even stopped over at Sturgis for a few hours in the rain.

Problem solved!  Blocked spark plug hole drain.  I can sleep now.  Thanks to everyone for your help especially John who got my photo up.  It is now 65 degrees in Oregon and my Valkyrie is getting new tires so have to ride bike #2, my Vmax.  In the future I will inspect all spark plug holes after washing the bike.  Spring is coming to all riders not fortunate to live in year round riding locals.  Woodeneye.

You might be best to minimize hose use on your bike, particularly around the engine. That orange goo was something to behold. FWIW  ???

???????? Why is that? Have you ever ridden in a downpour? Water on the engine will hurt nothing unless a plug is out or there is a leak in a gasket somewhere.

Honda didn't design them to be "waterproof"

Only "water resistant"

Like when riding in the rain!

If the hose mimics rain, then Ok, but water under pressure,,,

+1  cooldude IMO hose use has to be followed by a blow down and a wipe down.
