Inazuma 400 Flat-Rate Motorcycle Inspection and Self-Point Maintenance

Actually, I had been asked to do front maintenance (stem+) ★
My apologies.
Front maintenance (stem+)………¥29,400 Restores nimble handling.
 

 
Today the steering head locked up nicely ★
 

 
When everything goes all loose and droopy, it puts strain on the harnesses, hoses, and wires,
so it’s safer to be as gentle as possible.
 

 
I see! There’s quite a bit of oil residue.
But the feel when riding and when pushing didn’t seem very good, though…
 

 
It’s heavily corroded.
 

 
The corrosion has eaten it full of holes ★
When there’s plenty of grease, the oil makes corrosion less likely,
but water inevitably gets mixed in.
In the end it becomes a water-and-oil situation, and corrosion quietly progresses,
so we end up disassembling, cleaning, replacing the grease, and swapping out bearings.
Steering stem, swingarm/linkage area, and wheel bearings—
broadly speaking, just these three spots!
Surprisingly few, really.
 

 
We snap it in and do a visual check one-two
 

 
I think, “Aha!”
 

 
And it’s running beautifully and nimble now ★ Test ridden
 

 
We also adjusted the fork oil settings.
 

 
They asked me to do something about the ETC antenna ★
Well, it certainly is built pretty robustly, but it’s excessive and pointless rigidity.
I came up with a good idea, so I’ll make it tomorrow ~
