Rich oil cooling? “Oil-cooled 1200 series late-model alternator” Overcharging has started?

Finally, overcharging has started…

If we’re talking about Z, Katana, and GS
it’s a standard

rear generator
*alternator
job, especially for Suzuki, which is not something you hear about often
as a case

Finally, the baptism of an old bike? It’s begun.
By the way
this is about the Bandit 1200/Inazuma 1200/GS1200SS.

Note that the GSF1200 is different.

Since the regulator and brushes are inexpensive
it’s fine to replace them before they’re discontinued
the ASSY is a bit…
I recommend it for those people (*´ω`*)

The ASSY is still available!

Alternator ASSY 31400-03F40
*This is the final K6 and similar models
Can be used on all oil-cooled bikes, but…

You’ll also need bolts as a set
You need to pull out the damper housing with a puller
.
Even if you buy it, you’ll have some trouble.

Let’s remove the regulator!

Three Phillips screws and one 10mm nut
The cover opens easily~

Wow
the serviceability is really good~

Almost everything comes off with Phillips screws~

Remove five bolts and
you get this state.

If you do it right, you might be able to do it while it’s still on the bike~

The brushes still have some life left, but…
Since they don’t cost much, a set might be better.
