It seems it had been sitting for quite a while… It’s clean, but it’s showing its age.

Complete fuel system failure means the tank, fuel pump, and fuel sensor are all dead.


The tank can’t be cleaned to a usable level, so I’ll search using the web.
When I cross-reference the part numbers for the A-type and B-type, they’re completely different…
Since I’m searching for used parts, what’s listed isn’t necessarily accurate, so I have to look carefully, extract the differences, and make sure there are no mistakes—it takes several hours.
Finally found this beauty above.

It gets even worse when it dries… looks like a croquette.

Yikes… scary. Everyone, please don’t let your fuel go bad!
I didn’t think it would work this well, but Fuel One might be the ticket.

I drained the engine oil. No water contamination was detected, so that’s reassuring.

This time the battery is Daytona brand. It’s affordable and I use it quite often.

What makes it reliable? I choose products from well-known domestic manufacturers with a warranty.
Some people throw away their battery warranty cards, but you should absolutely keep them.

The plugs had iridium tips. They’re clean, so I’ll reuse them.
Just changing the ZX12R plugs is enough work to make you want a full service. If I had more customers, I’d definitely create a special tool for it.

Surprisingly clean—I was relieved.

Surprisingly unused and clean. No weathering either.

With the plugs out, I cranked it firmly until the oil pressure light went out… whirring away.
That’s fuel injection for you. It started right up.
No unusual noises—all good. 
I have to remove the throttle cable too just to get the plugs out…
Now I can finally order the parts.
Putting it on hold for now.
