1982 G1100 engine rebuild?

Postby glasgowjim » Mon Mar 11, 2013 3:36 am



After 44,000 miles and several months storage, engine developed a heavy knock, left muffler turned blue, backfire etc.
I pulled the motor, replacing with used motor. I am thinking of tearing faulty engine down in hope of discovering some easy fix. Have any of you undertaken such a project? Hints on how to? I lost my Service Manual.
Installed original carbs on used engine, any suggestions on tuning, balancing? Used engine running a bit rough.

The heavy knock is what I'd be looking into first.....Check the timing belts....Do a compression test....Cracking the case open for a look see is just about as far as it will go.If that engine has a knocking crank,you've got a 380lb paper weight.
Now if the knocking from the old engine can be attributed to a carb problem(rattle from a idle to 1500rpm),you should see a poor running replacement engine too..
The engine will rattle quite a bit if the 4 carbs are not right.....as in,clean and properly synced.

I'd tend to your bike first...get the carbs right and the engine smoothed out....you may find that the other engine is still OK.

All the info you need is here in the "How to" and "Manuals" section besides looking over past posts about "how to sync your carbs","$25 dollar sync",and don't forget about the electrical system either....3 yellow wires....
Plenty of reading and much to do..Have fun... :D

I did rebuild a 82 gl1100.
Total cost was just over $400 in parts.Excluding the main and rod bearings.
I'll never do that again.Part time took 2weeks of labor and 3 months to get all the parts.
After I finished,I found a running engine on a ugly bike for $500.
My labor was worth more than the $100 more.
20/20 hindsight.

Makes sense to me,dosent seem worth the bother when you can buy a running used one for that price. Regards, Johnyy

I would go the other way, you had the chance to check everything in your old engine and replace any worn parts, it should now run for another 100,000 miles. If you buy a running engine, you have no idea of its condition or history, it could fail 100 miles or 50,000 miles later. I would much prefer to spend a bit less cash, more of my time and know the exact condition of my engine.. :D

I guess that's just me!! :evil:

Many thanks for valued input. Will try tuning used engine, run SeaFoam, change oil - hope for the best.

Gary...I agree (I was a bike mechanic; Triumph, Norton, BSA, Vincent, Ariel, AJS, Matchless and the like decades back. We had a trained HONDA mechanic for the Dream etc. Jap engineering being quite different and, they didn't leak oil!)

If I get up some ambition may tear down 44.K motor for fun. IF I find reairable damage, will replace in otherwise nice looking '82 GW I have owned for some ten years or more. Thanks to all for advice.

I agree...the engine I rebuilt had 150k+ miles on it....All I really needed to accomplish was a re-ring and valve job....the rest was still in good shape.Just low compression.
