Question about sprocket width

[Tallemertes]

I'm getting a new sprocket and the gs wiki calls for a JT 516 and the width is 8.8 The sprocket I'm looking at is a JT 516 but it has a 8.5 width. Will the skinnier sprocket work? will I need to add a washer or something?

SHOULD work. a washer if you can find one to fit would be nice though

There are 2 thicknesses of sprocket hubs for the GS500.
Old ones are thinner. Newer ones have a thicker hub.
You should use the correct one for whatever year your bike is.
JT has both thicknesses.

There is the third sproket that has no shoulder (hub).

The JTF516.16 fits all 94-09 GS500/E/F models.  Use it and don't worry about it, the difference is insignificant.  Current width over the hub of that part is 8.5mm per JT site dimensions.  The JTF565.16 without a hub is used on 89-93 GS500 models, that one is narrower, fits the 1/4" space between 520 chain link side plates.  Wiki is outdated on that 8.8mm dim, should be 8.5mm.

That's really what I meant to say......
There are 2 types - with and without hub.

OP was questioning the 2 different dimensions shown for the JTF516 sprocket with a hub.
