The town has a bit of a summer vacation vibe, which is nice, don’t you think?

Even Tokyo’s somewhat quiet streets during this time are quite pleasant. That said, with weather like this, I don’t even feel like taking it for a test ride.
Now that all the parts have arrived, I’d like to get the work done smoothly. <\/p>\n\n\n\t\t

First, I’ll replace the Bridgestone BT46V tires. <\/h2>\n\n\n\n
\"\"<\/figure>\n\n\n\n

The ever-popular Bridgestone BT46V, indeed.
I’m grateful that they continue to carry this niche size. <\/p>\n\n\n\n

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

I’ll use a Dunlop JS430 air valve.
Since it’s currently tubeless and the service life is unknown, I’ll replace it along with the tire. <\/p>\n\n\n\n

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

Be sure to check for any air leaks.
Rather than using soap bubbles, this method has less risk of residue, so I prefer to use this type of tool. <\/p>\n\n\n\n

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

Match the heavy spot on the wheel side with the light spot on the tire to offset them.

On stock wheels, the air valve position is usually not the heavy point.
If you align the tire’s light point with the wheel air valve as instructed,
the amount of balance weight needed can increase.

If you check the wheel alone and balance it that way, you can reduce the amount of weight needed.
By the way, with aftermarket wheels, the air valve is almost always the heavy point. <\/p>\n\n\n\n

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


I’d like to give the inside of the wheel a nice wax coating.
Even though the inside won’t be visible, it makes the next service much easier.
It doesn’t affect performance, but it should feel good mentally. <\/p>\n\n\n\t\t

Both front and rear were fine.
Depending on the manufacturer, even new ones can be questionable, so you don’t need to be overly concerned. <\/p>\n\n\n\n

I’ll replace the battery with my favorite Pro Battery gel type. <\/h2>\n\n\n\n

Previously, WESTCO was the only gel battery option available,
but since Custom Japan released their Pro Select Battery gel type in recent years, I’ve been using that.

Despite the low price, the performance is stable, so I don’t mind replacing it before it deteriorates too much.
Since batteries are fairly expensive, you tend to want to use them until the last moment, don’t you? <\/p>\n\n\n\n

<\/div>\n\n\n\n

While replacing the battery, please also check the charging system. <\/h2>\n\n\n\n

The three female connectors coming from the generator get hot and are prone to burning.
Recently I’ve prepared perfect countermeasure parts, but if you maintain it regularly, it’s surprisingly okay.
It’s also important to disconnect and check them occasionally to prevent burning.

If the battery terminals are corroded, polishing them will increase your peace of mind. <\/p>\n\n\n\n

The plugs are really fouled up\u2014it was like an injected bike.
I want to go maintenance-free for the next two years if possible, so I’ll replace them anyway.

I’ve replaced the engine oil with Shell Advance Ultra 4T.
