81 GL1100 engine help

Postby dramsell » Sun Jul 27, 2014 3:26 pm



I have a 1981 GL1100 I bought used with 30,000 miles (they tell me). It has a tick in it on the left side and I am trying to diagnose it to see if it is safe to ride. I had new belts put on it, oil change and valves adjusted. Still there.
I am going to try to upload 2 videos where you can hear the sound. Any help would be greatly appreciated.

I can hear it...what oil did you put in it? Also, did you adjust the valves yourself, or have it done?

I do not know what was in it before (made sound before work), but I put GN4 20x50. I had a honda garage do the valves and belts.

Well it does sound like valves to me, but without having done them yourself, it's tough to say if they were done exactly right.

In your opinion, should I just ride it?

Adjusting valves isn't real hard. I didn't play the video, but if you think your valves are not adjusted correctly, or even suspect it, riding it isn't what needs to be done. The procedure isn't difficult. What you need is a shop manual, some feeler gauges, a wrench or two and probably a screwdriver. You'll have to remove the plug on the rear of the engine, the timing plug on the top center of the engine and get an offset wrench that fits the bolt in the rear of the engine to turn the engine over to line up timing marks.

If you just paid someone else to do this work for you, perhaps you should let them listen to the sound the engine males and see if they agree it is valve noise. There ought to be some kind of warranty on repair work. I know if I did work for someone and a couple of days after, they had the same problem I told them I fixed, I'd want to know about it... and I'd do the re-work for free. Obviously, I'm not a Honda Dealer, so don't expect they'll do anything for free because I think they should.

The sound could be unrelated to the work they did. Viscosity of the oil can effect the sound of the engine, as can other factors... bad gas, plugged fuel filter... there are a lot of variables.
I am wrong as often as I am right concerning what is wrong with someone else' motorcycle without having seen the machine in person. Guessing with limited information, as to the source of the trouble, is sketchy at best.

When I adjust valves on my 1980, I find it works much better if I adjust each cylinder by itself at top dead center (firing stroke) rather than possisioning the crank at a spot and adjusting certain valves at cylinders. The way that I set mine is the "double checking" step in the manual which does indicate the back side of my cam lobes are imperfect.

I've been reading the GL1100 pages pretty heavily for the passed few weeks and what grabs me here is the 20w50 oil. People seem to either stick with the Castol 10w40 motorcycle oil or migrate to the 5w40 Rotela diesel oil (both work well with wet clutch). Yet everyone in the big 3 forums freak out with 20w50 in the gl1100.

I'm just sayin'

If you look at the oil viscosity recommended for ambient temperature riding in your area, I'm reasonably sure 20-50 is okay. I'd never use it because I often ride in the winter when it is in the low 30's or high 20's outside, and the engine would not flow enough oil at those temperatures to get lubricant to the engine parts in a timely manner.

I figure it's your motorcycle, ride it and treat it however you want. Lots of folks use 20-50 oil in motorcycles. I don't, but that doesn't mean you are wrong if you use it in yours.

I have a1980 .gw that I purchased 12-2-13 (neglected and had to rebuild crankshaft), that I tried different oils in, and royal purple 20w50 car oil performs phanomally. It is supposed to be the best by some, and the worst by others. Research.... :roll:

I had that same sound, it went away after I readjusted the valves....
