I use Honda Bond 4 for metal to metal (engine cases and such) and gaskets was well. Really good product.

I'll second that. Used for case jojnts on 2 strokes that must be air-tight with no gaskets. Several names for it (Yamabond, Threebond, Honda Bond 4, etc.) but the same great product. Usually available on Amazon. Not as easy to remove as Indian Head, but seals better.

I've got a tube of Threebond ready to go, actually. Funny enough, it was closing up the cases for my CB750 (and using the proper sealant for it) that got me wondering about my GL1000 problem. I'd never sealed that area up between the cam holders and heads before, but something "clicked" after my 750 job- why not? It's metal to metal, but there's shockingly little documentation of it actually leaking for others.

Ah well. It was just nice to confirm it before tearing everything apart again.

I'm genuinely disappointed I've had to get to a point where I can get this apart this much, this fast.

Image

I managed to get the left side apart, sealed, and back together, but.... I may try again once it dries. I got both the cam towers and the head nice and clean in the sealing areas while it was laid flat, but as I was bolting it up vertical some of the residual oil on either the head or the cam leaked down near to where the sealant had been applied. I'm about 70% positive it's fine, but I'm not going to tear it apart this far again in case I get hit with the 30%.

Still, hard part is done, and I'm REALLY looking forward to a bike I can ride and not have to worry about.

UPDATE: I was still up and about, so I took things apart, cleaned them better, and re-applied the Threebond. I definitely feel better about it. That said, from the old sealant that was left on from the first try, you can tell that the tolerances were MUCH tighter on the front than on the back (despite being torqued down correctly).

I had a thin film of oil coating the inside of the timing belt cover, so it was leaking on that end too. But not nearly as bad as the rear.

Regardless, I'm genuinely hoping this finally gets it done.

Right side done. I probably could've left it, but I had it apart, so my as well. The back obviously runs the fuel pump, so no seal back there. However, there IS still a tiny strip of metal-to-metal, so that got the glue treatment. The front actually gave me a bit of trouble coming apart, despite only being together for a handful of miles. There was a bit of schmutz that I would almost guarantee was the remains of the previous round of sealant (factory or otherwise), and it was enough to keep the front clean. Still, I got some proper sealant there too, so I don't have to worry about it.

Next up? All the "normal" stuff: belts, valve clearances, timing, etc. Thankfully I've had plenty of practice with that, too.

In the grips of winter, motorcycle life is slow. I managed to get the engine sealed up and everything set up enough to get it to run, and.... run it does. Quite well, actually. Well enough that even though I only roughly set the ignition timing via witness mark, it goes pretty well.

The good news? The oil leak is taken care of, or at least taken care of enough. I've put a number of heat cycles though the engine in the past couple weeks, and nothing I see makes me think I've still got problems. Well, oil related ones in any case.

I DO have a last little thing I'd like to button up before spring, namely a coolant leak on the upper coolant hose attachment by the thermostat. This has been an issue for a while that seems to come and go, and there's evidence it had been going on since before I bought the bike. I did replace the hoses with the cut-up Gates hoses, and the lower works fine. But the upper has always given me fits. I've currently got my clamp pinched down all the way, and that just barely seals it. I figure I've got time to fiddle with things, so here's the plan.

-New hose (ordered)
-Clean up the upper thermostat hose barb. To the point of polishing the sucker.
-Worst case scenario? Some type of sealant.
-Ultra worst case scenario? Spend 100 bucks on silicone hoses.

not an idea... this is a SOLUTION. First time I utilized them on trike's internal combustion engine was mid-2012. ;) ;)
Several times since then and never experienced a single solitary coolant hose leak.

A Gates video advises as long as you can apply heat, at least 120 degrees around its total circumference, the thermoplastic hose clamp will shrink down completely tightened.
https://www.eastwood.com/images/pdf/31444Q_inst.pdf
Shield the wires' insulation behind the clamp from the heat gun air blast and git er done.

note: " * Conform to any shape of hose and housing, even out-of-round fittings. "

completely scrape the scale off the thermostat cover's hose nipple... down to CLEAN metal.

Done.

Fun day in the garage today. My heat shrink coolant clamps and new upper hose showed up today, so I decided to get my coolant leak buttoned up for good. And in ways that shouldn't be surprising to me, yet someone still are, I found a new way to make things worse.

I got the radiator off, and discovered that my coolant leak was probably part of the hose that had managed to get folded over when it was installed last time. Still, I had a new hose, and I'd never been a fan of the Gates hose I replaced it with- it's just a hair oversized, and it doesn't fit right. Anyway, new hose goes on (purchased from eBay), Gates clamp goes on, shrinks down nicely, pop on anti-kink spring, get radiator in:

Hose won't attach to the engine block.

Thing is, a combination of a slightly smaller ID, a VERY weak wall (hose folded over rather than slipping on) and a slightly smaller OD (that meant with the spring it was impossible to get a grip on the hose and force it down) led to a radiator that refused to go on. After a lot of effort (and I'm pretty sure a bunch of newly invented swear words) I gave up, threw the hose away, and walked away for the night to decompress.

I'll get back to it soon enough. I need to re-evaluate my options anyway.

If nothing else, I never fail to amuse myself with new and different ways I make things difficult.

Yellow '76: I'll Get It One Day - instructions for success

Set the anti-kink coil spring and second hose clamp aside for now.
Concentrate on the aluminum alloy thermostat cover hose nipple and its Gates heat shrink hose clamp, FIRST.

Got that thermostat cover heat shrink hose clamp tightly installed on the aluminum nipple now? YES!

(I'd strongly advise You get somebody to assist and securely manipulate the radiator as needed to complete this cold weather project)

Next, push the radiator far enough forward to disengage the upper end of the radiator hose, slide the anti-kink coil spring onto the loose upper end of the radiator hose then twist and compact the entire length of spring coils tightly against each other and the edge of the heat shrunk lower Gates hose clamp, too.

Doing so will provide adequate space to slide the upper Gates hose clamp onto hose itself, then push the hose onto the radiator nipple.
You can figure out the rest on your own now. ;)

Bad news first- I went into my garage today to check on my little fleet, and noticed that for whatever reason, be it fuel, oil, or various coolant leaks, quite a bit of paint had bubbled up on the top of my engine block. Unfortunate.

On the plus side? It was 50 degrees out, and you can't see it from the saddle.

Image

Image

It ran rather well, especially considering my ignition timing is just off a set of witness marks from the last time I pulled the timing plate. On the plus side, no leaks that I could see, oil or coolant. The paint thing I'd like to address at some point, but that will involved carb pulling, and for right now, that can wait. I'm just happy for some saddle time.
