Pulling engine gl1100

Post by shevik » Sun Jan 12, 2020 3:31 pm



Hey friends,

I'm helping a buddy rebuild his wing after a gnarly accident. It's had a bad sprag clutch for a while now and seafoam never did the trick. Time to pull the engine. What else should we do while it's out? I've considered a new stator because I've read they're prone to failure.

Any advice much appreciated!

If I just work hard enough I should be able to get her out and about before riding season is over.

stator - If it isn't broke don't fix it. It's usually external factors that kill's em, (shorted/burnt connectors, bad rec/reg), they don't usually go bad on their own. Inspect the shellac insulation on the stator windings, dark shellac is ok, crispy/burnt shellac is not. Replace stator if insulation looks crispy, otherwise I'd leave it.

The oil pickup screen is impossible to get to while engine is in frame, a good time to clean that.

Neutral switch on the early 1100's is on the right side of the engine is right by the oil pickup screen and can't be serviced with engine in frame. If his neutral light was working as it should I wouldn't worry about it, but mine is stuck "on" so I pulled the neutral bulb out of the dash so I wouldn't have that green light glaring at me going down the road. :mrgreen:

Vacuum Advance on rear of engine can be checked if you have a My-T-Vac brake bleeder tool. Timing advance plate should move at around 3-5 in/hg vacuum.

I'm sure someone else will chime in with other things.... Good luck :) :)

I'm at the tail end of an engine swap. I'm trying to remember the details from when I took it apart 6 months ago. The vaccum advance on the tail end of the block (near the gas tank) has a nib for a vaccum line...Where does the other end go? I think it's the carb assembly but I'm not sure. Am I on the right track?

Additionally, There's a wire on the bottom right side of the block (in the front that is) the old motor had 2 leads with a plastic connector. The new one has a single lead without a connector. I can't figure out which wire that needs to connect to. HELP!

There will be a vacuum nib on Carb #3 for the vacuum advance.

The neutral switch connector with two leads will most likely be a ground lead and one that lights the neutral indicator when grounded.

To figure out which of the two neutral switch leads to connect to the single terminal neutral switch on the new engine, you will need to temporarily connect your battery (I assume it's disconnected while doing this work) and turn ignition on.

Ground each of the two leads, the one that lights up the neutral indicator when grounded is the one to connect to the single terminal on the new engine.

Thanks Denver. You confirmed what I was already thinking and your advice for figuring out the neutral indicator will be a big help. I've collected all the pics from this project and expect to post the final project soon.

Hate to bother you again but if you don't mind another question: I've lost the temperature sensor (sending unit) that plugs into the waterline on the thermostat. Can the motor run/function efficiently without it? Meaning: I really don't need to know the running temp because I won't have a gauged for it anyway. Should I jump through the hoops to replace it?

You can certainly run without a temperature gauge, there's another way to tell the temperature anyway - Steam = overheated. :lol:

Not sure what you mean by "lost", if the sensor is missing you will need to find something to plug the hole to keep coolant in the engine.... but the engine does not require the sensor to run.

Now if this is the fan sensor switch and not the temp sensor for the gauge (they're both in roughly the same place), I'd be a little more concerned. You'll be doing a lot of steaming at slow speeds without it.
