Changing the head gaskets on a GL1200A

Postby Gusbike1987 » Thu Sep 22, 2016 9:34 am



This may sound like a silly question but is it possible to change the head gaskets on a GL1200 without pulling the engine?

I just looked at my 85 again,and dont see any reason too. Unless you just want the practice? :P Looks like a lot of work either way.

I was given a 1987 Aspencade that needed a lot of work just to get it to start. When I finally got it running, I noticed no temp readings but the reservoir was filled with coolant. I went back to my Clymer to trouble shoot why the fan never came on and no temp showed while it ran. I finally opened the radiator cap and added coolant and found it was actually empty. When I started it back up it bellowed steam out of both tail pipes. Do you know a procedure I could follow to replace the gaskets or do I just have to wing it?

Thanks for your reply,
Gus

I have never pulled the heads but there are several on here that have. Make sure to check the heads for cracks if & when you remove them.
Did you put cold water into a hot engine? If so you could have cracked both heads. Hope just head gaskets/expect more.

Pretty easy to do without pulling motor. Carbs can be strapped up to allow access. Exhaust can be left hanging below.

If you haven't done it before, it's intimidating and not keeping things lined up can result in failure. There are several good write-ups/how-to's around. Read and watch them until you're sick of them.

Plenty of help here if you get stuck.

You'll need two orings per side for the oil restrictors or along with the gaskets. Available from Honda.

If you haven't seen these, here's a couple of videos that are good to watch. One is installing the heads and the other is replacing the timing belts. You'll need to be familiar with these in order to do this job. It can be done with the engine left in the frame.

I just finished up mine on the Aspy- very intimidating, but when you're done with it, you'll feel great. My biggest concern was all of the smoke that poured out of the exhaust after I was done- keep in mind, there is probably residual fluid from the bad gasket leaking left in the pipes. Let it run, keeping an eye on the temp, and it should clear up. After that it oil-smoked till I gave it a 50 mile shakedown, that sealed it up good.

I found that a dremel with those spongy polishing wheels work fantastic to get the old gasket off, but you need to take your time on it. It goes through a LOT of them, but it's so much easier than chore-boys.
