18 Years of Truth? Bandit 1200K6 Inspection Yoshimura ST-1 Cam Oil-Cooled Maintenance DID Drive Chain Replacement and More

Yesterday I was in meetings all day and left early, so there was no blog post.
Today I’ve been working hard since early morning and I’m at MAX.

I’ll continue with the oil-cooled maintenance.

Basically just wiping and cleaning.
I use parts cleaner sparingly at the end (it’s expensive).

I pull out dirty rags (their final duty) and soak them in wash oil to wipe everything down.
Interestingly, bikes that are greasy with oil actually clean up to reveal cleaner insides.
Probably they’re less prone to corrosion.

I’ll remove the generator and starter motor.

You two come off so easily… I’m grateful.
Modern bikes, on the other hand… well…

I cleaned it up as much as I could (*´ω`*)


Cleaning the starter motor mounting surface (case side) gives you extra peace of mind.

The generator damper was also stiff (*´ω`*)
The engine noise should be a bit quieter now.

For the shift oil seal, warm it up with a Makita heat gun.

This time there were no leaks yet.
After the bike has gone a certain distance, it’s a good idea to replace this part.
Ask your bike shop to do it when you replace the chain and sprockets.


Make sure to warm it up thoroughly after lubricating.
The probability of it coming out on the first try increases dramatically.
If it doesn’t come out, you’ll go “straight to the first circle of hell, so approach it with 90% preparation?” mindset.

Tap, tap… tap, tap… it came out on the first try (*´ω`*)

I’ll seal the lip with fluorine grease and install it with the hope that it won’t leak as much as possible.

To be continued.
