recently changed my coils.oem ones were cracked open.
when i changed them i didnt have this white "thing" and bracket seen in the picture

No idea if it is critical.

It is the resister for later 1100's.
My 80 engine cracked it's coils. I went thru 3-5 sets of coils before I found coils that matched the numbers on my cracked ones.
I could never get the engine to run right with the other coils that did not match the original ones. I took the resisters off and all kinds of configurations.

so its a resister?
i know you need at least one resistor..right?
does our plugs have a built in resistor?
my gl is an 1980 model
whats the benefit of having one of these resistors mounted?
tnx

The white "thing" reduces voltage to the coil after starting. Do you need it? Yes, if you replaced the coils with honda coils. After market check with manufacture. You need resistance in the secondary side of the system either in the spark plug wires,or resistor in the plug cap or spark plugs. The spark plug will have a R in the plug number. The coils will discharge to quick without resistance resulting in a less usefull spark and create over heating. Go over to randakks cycle shack.com and in the 1100 section you will find plenty of info on the ignition system. Hope this helps...

one's i have removed, didnt have a "white resistor"
neither the replacement coils
spark plugs have an "r" in the serial
hope its enough

My wiring diagram does NOT show the resistor for 1980 (used only on GL1100 - 1982 ??).
My actual bone-stock '80 does NOT have the resistor. Usually such resistors are used to reduce nominal current (heat), but are bypassed during cranking for easier cold starts (since the starter motor current draw reduces battery voltage temporarily.). But the circuit diagram I have shows the resistor (if present) does not get bypassed, and is in the ground side of the coil circuit full time.
I suspect that models which do have the resistor use a coil with less internal resistance, vs. those that don't.
Therefore it would be prudent to use the exact same spec on the coil you are replacing.
The resistance in the secondary serves a different purpose, and your "R" spark plugs should take care of that.

You know thats right. fubar.. they did change coils plus a different part number didn't mean to steer you wrong. you should be good to go
