Watanabe Full Power KIT installation and ELF MOTO4RACE oil change, among other services requested.
First, we start by fabricating a bracket for the Watanabe coil. While a blue bracket would work fine too, taking this extra step improves maintainability and other aspects.
The process is: keep it as thin and light as possible, add ribs, perform barelling, tack-weld the nuts, and so on.
*Please note: we do not perform relocation or bracket fabrication after installation by other shops or individuals.
We could have lightened it further, but due to time constraints we stopped here.
Lately, Watanabe coils come with rubber covers, which seem convenient. I worked on one recently, and just the other day it came loose inside the cover—even with two cable ties securing it—so I’ve lost faith in them! That’s why we do it this way.
This shrink tubing can be cut off with a cutter. If you use heat-shrink tubing instead, it won’t come loose even if you pull on it. We’re promoting the welded version for safety and reliability.
So that no one makes a mistake in the future, we label everything with a label maker—an old-timer’s essential tool.
We label the cords too. The old method used shrink tube marking, but it tends to fade, so we switched to tape.
The plug cover will finish cleanly if you punch it out with a 20mm punch.
We replace the spark plugs. For some reason, these are resistor-less.
Please widen the gap. Rather than prying it open, it’s better to hold the right spot and adjust carefully.
And when mounted, it looks like this. Understated and good!
I sometimes see bikes where someone installed it themselves and made the plug cord too short, resulting in poor maintainability. If you lay it out a few times and think through “installation and removal for maintenance,” I think you’ll get a better result.
And just like that, we’re done—here’s the Watanabe unit mounting bracket. You could just stick it on, but “if it were my bike, I’d absolutely hate it, so the customer’s bike should be done right too.”
We secure it with sponge, dual-lock adhesive, and cable ties—nice and subtle.
It sits inside the right tail cowl. Of course, you can’t turn the dial, so be careful.
That incredibly sturdy bracket—we polished it up nicely too. 52 by 10 millimeters? That’s impressive.
As we head into the harsh summer ahead, we’re using “ELF MOTO4RACE 10W-60.”
Its heat resistance and durability are excellent.
We changed the engine oil and filter.
Replace the drain bolt once in a while too!
One spark plug is out of stock, so that wraps it up.
