1100GL motor swap

Postby jasonm » Sun Jun 24, 2012 6:10 pm



New to goldwings and i just bought a 1982 1100GL Interstate Goldwing. I was wondering If all Golwing 1100 motors are the same. I've seen manuals that say from 1980-83 so i wasnt sure what to look for when looking for another 1100 motor.I would appreciate any help i could get.

Thx,
Jason

I am not a GL1100 expert, but I am pretty sure any GL1100 motor will fit in any GL1100.

Physically, they will all fit. There are some minor differences in gearing, electronics and so on.

thx for the replys. As I have found out today there are frame issues from year to year and from model to model with these engines one being where the hangers are. I was also hoping to be able to swap out parts from my motor to the other motor. I was looking into getting an 1982 aspencade 1100 with no carbs or intakes. Come to find out my 1982 interstate 1100 carbs and intakes wont fit go figure. Now i didint phically try this but what a honda mechanic told me. They told me honda was good for this they designed the motor around the bikes so there seemed to always be something different on each modle and year. Sounds like what FORD was always good for,lol.

Tell your Honda mech that he doesn't know what he's talking about!

ALL GL1100 carbs and manifolds will fit ALL GL1100 engines!

All GL1100 engines will fit ALL GL1100 frames! There are NO differences in the hangers or anything else.

As Admin says, the differences are in the wiring connections and internal differences in the gearing.

(In fact, with slight alterations, all GL engines will physically fit in all GL frames, though I doubt you would want a 1000 in a 1200 :roll: )

Yup, but as you and Randell both say, everything affects every thing.

well thanks for that info and to think I thought this guy knew what he was talking about. Ok then Can you tell me what the difference between an 1980 1100 interstate motor and a 1982 is? I found this one but if theres a difference in the wiring Im not really up for that. Just to comfirm All motors from 1980-83 in a goldwings are GL1100 ?
Thx,
Jason

As far as I remember, the only wiring difference is the single wire to the neutral switch. The 82 has the switch behind the front cover, rather than down in the right side crank case as on the 80-81. That should not be beyond your capabilities to hook up.

All 80 - 83 are 1100. Third, fourth and fifth gear were raised in the 82 &83, along with very slightly lowered final drive. You will find that an early engine in your 82 will rev a bit higher for any given speed, especially in fifth.

Correction to my last post. You can't fit an injection 1200 into a 1000 frame, due to the larger rear case over the bigger alternator.

Thx again guys for the replys. One more question will there be any issues using the 82 shaft drive with the 80 motor? or they all the same too?

As far as I am aware, there is no difference to the hook-up to the drive shaft. The different years have different part numbers for the output shafts but I'm sure that is internal differences, not external.

Thx old fogey.Now you said something about the nuetral switch wire. If it doesnt get hooked back up it wont affect anything will it? Its just for the nuetral indicator light?

It should be easy to link it up, as it is a single wire. You will have disconnected the wire of the 82 from the harness when you remove the engine (it's on the top of the front cover). Fit a single wire to the neutral switch down on the right side of the 80 crankcase before you fit the engine and run it up ti the harness connector.
Should be easy, but if you don't do that you will need to ground/earth the harness wire to the engine or your starter circuit won't work (I think that is right. Doing this from memory as I don't have the wiring diagram to hand).

Thx again old fogey. If I buy this motor I'll get back to on how it turned out.
