I’m back from that hellish same-day surgery.
I really think you should avoid same-day surgery at all costs\u2026.
I’ll write another blog post about this painful experience, so if you’re considering deviated septum surgery, please refer to it. <\/p>\n\n\n\n

The oil pan machining is complete, so I’ll assemble it smoothly. <\/p>\n\n\n\n

Maintenance log for this article<\/span><\/strong><\/span><\/div>
\n

Vehicle:<\/strong> Kawasaki Z750FX-1<\/p>\n\n\n\n

Verification content:<\/strong> First oil change after relocating the drain bolt on the oil pan. <\/p>\n\n\n\n

Previous procedure:<\/strong> Loosen the exhaust flange, remove the tailpipe, shift the collector\u2026\u2026 (over 30 minutes required). <\/p>\n\n\n\n

Current procedure:<\/strong> Place an oil drain pan underneath and loosen the drain bolt (3 minutes required). <\/p>\n\n\n\n

Conclusion:<\/strong> I’m convinced that oil pan modification is the “best value-for-money” custom for Z riders. <\/p>\n<\/div><\/div>\n\n\n\n

I’ve been passing it off to Fujitake because it was a hassle! (\u00b4\u30fc\uff40)<\/h2>\n\n\n\n

Fujitake Metal<\/a><\/span><\/strong>
Currently, blog updates are on hold due to being busy. I created a new webpage, but\u2026
I need to improve SEO measures further.
The reason isFujitake Metal<\/a><\/span><\/strong>Homepage“Currently doesn’t show up in search results at all.”<\/span><\/strong>It’s like that.
I almost wonder if it’s not even published\u2026. Go Gamba Osaka.

The other day, I removed the oil pan and asked them to wet blast it and send it.
Oil pan = cast iron \u2192 soaked in oil for years \u2192 cast iron + oil penetration makes welding difficult = that’s the Fujitake flow.
As expected, they finished it with ease and confidence. <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

I adopted a Suzuki fine-pitch M14-P1.25 drain bolt. <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n


Of course, this has been wet blasted one final time, so it’s finished even more beautifully (*\u00b4\u03c9\uff40*)<\/p>\n\n\n\n

Oil pan removal and installation work is super efficient with a lift? <\/h2>\n\n\n\n
\"\"<\/figure>\n\n\n\n

We alsodidn’t have a lift in the old days, so we really struggled. <\/strong>
You can’t get lower than the floor.

I’m really grateful to T-san for that.
Both lifts were permanently loaned to us by T-san, so we’re grateful to use them. <\/a><\/strong>
\u2191Blog<\/p>\n\n\n\n

I pretty much understand why people hesitate to invest in a lift.
The issue of effective land space<\/span><\/strong>
Just having a lift imposes significant constraints, so for shops in urban areas without much space, land is a critical issue.
But with a lift, efficiency and fatigue levels are completely different.
I’m not a fan of toilet bidet seats, so I wouldn’t know, but
“bidet”<\/strong>feels kind of like that? I think. <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Vehicles with engine overhauls are nice.
It came off pretty cleanly\u2026. That’s reassuring.
Whether the gasket remains on the case side or not makes a huge difference in labor.
Gasket removal is such a pain that you can’t really charge double labor\u2026. That’s the reality. <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

They’re keeping it really clean.
I wonder how many engines I swapped in the old GSF I used to ride\u2026.
Because I treated it so badly, I was swapping engines every year. *Swapping the engine was faster and cheaper than changing the transmission
I was thinking about that while looking up and scraping off the gasket. <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Torque is applied, so I cut off the excess just barely. <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

I replaced the bolt with a Honda OEM flanged bolt (steel). <\/p>\n\n\n\n

All Zs should be like this<\/h2>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Of course, since it’s on the right, you have to tilt it upright or slightly to the right, so it’s harder to drain than stock.
That said, there’s not a huge difference in volume.
Since removing the exhaust every time is a hassle, relocating the drain makes oil changes more enjoyable. <\/p>\n\n\n\n

After that, I’ll check the weather and go for inspection to complete it. <\/p>\n\n\n\t\t

Testing the Result: Oil Change on Z750FX with Relocated Drain Bolt.<\/span><\/div>
\n

Verification:<\/strong> Performed the first oil change after modifying the oil pan to move the drain bolt. Result:<\/strong> Previously, I had to remove the exhaust system every time, which was a huge hassle. Now, I can change the oil in minutes without touching the exhaust. Conclusion:<\/strong> This modification is a “must-have” for any Z-series owner with aftermarket headers.<\/p>\n<\/div><\/div>\n\n\n\n
