500SS MACHⅢ “Should Mach Get an MF Battery Too?” Inspection and Battery Replacement

The request was simply to get the inspection done.

Alright then! I fired up the engine. It ran rough on the first try, so I quickly swapped out the spark plug.
White smoke billowed out! I shut down the engine before the fire alarm went off.

Looking closer, I found it was overflowing badly, so I rushed to fix it.

Please take note, everyone.
Lately, gasoline seems to degrade more easily.
If you only start the engine occasionally, the carburetor will clog. The chances are extremely high.
Unless you run it enough to cycle through the fuel tank, you’ll run into serious problems.

I’d strongly recommend replacing wet-cell batteries right away.

  • You can switch any bike to MF without issues.
  • AGM = Absorbed Glass Mat
  • GEL = Electrolyte is gel = thick and won’t spill = can be mounted sideways too
  • Free from liquid top-ups and hazards from acid/hydrogen gas—clean operation
  • The price is reasonable, so you can replace it every few years if needed

Honestly, I think there are only benefits.
With wet-cell batteries, you’ll find almost no bikes without corrosion around the battery area and undercarriage.

The turn signals wouldn’t even light up, so I decided to replace it.

Double-sided sponge on terminal nuts is efficient

When purchasing a new battery, I stick leftover double-sided sponge from a certain battery brand
onto the terminal nuts before installation.

Just doing this from the start
prevents nut loss and makes terminal installation easier.
Making small things like this a habit really boosts efficiency

Be careful when opening! Electrolyte is dilute sulfuric acid. Hydrogen gas is constantly produced during charging

When battery electrolyte leaks, it leaves stains like this.
Since it’s dilute sulfuric acid, your hands will sting. It’s a serious caustic substance.

Of course it also eats away at iron like the frame, so you need to be careful.

During charging, hydrogen gas blows out from the overflow pipe.
By the way, if exposed to flame, the battery can explode, so you should be cautious about that.
I’ve seen someone whose battery exploded from grinder sparks during chain replacement.

By switching to an AGM/GEL battery,
you’ll have a clean battery environment, so it’s best to adopt it as soon as possible.

Is the weak battery a fundamental issue?

Both the crimping and soldering look questionable and sketchy.
If you notice and properly address these areas, you won’t have problems going forward.

We stock various terminal covers and used the one that matched.
*We happened to be out of red, so we protected it with a Kawasaki OEM black cover.

Always install a terminal cover.
I think a lot of people underestimate battery power.
It can easily set a bike on fire, so you really need to be careful.

That’s how we got the inspection done and completed.
