Year after year, rainfall is getting worse, isn’t it? We’re no longer surprised by 100mm per hour.
We hear about “record-breaking heavy downpours <\/em>” every week now.
Combined with frequent earthquakes
“Is Mount Fuji about to erupt?” <\/strong>or “The Nankai Trough?” <\/strong>\u2014we can’t help but imagine these scenarios. <\/p>\n\n\n\n

But seriously, everyone needs to start preparing in earnest soon or things will get really bad.
When it comes to heavy rain, “bikes get submerged,” <\/span><\/strong>right?
You might want to look for parking spots at higher elevations rather than underground rental garages\u2026
You also need to decide in advance where to move your bike during heavy rain.

Anyway, the bike is now complete and feels great to ride! <\/p>\n\n\n\n

Today’s Test Ride & Feeling Log <\/strong><\/span><\/div>
\n

Test Subject: <\/strong> Kawasaki GPz900R Ninja (A15 Model \/ Carb Overhaul & Frame Calibration Complete) <\/strong><\/p>\n\n\n\n

Situation: <\/strong> A summer afternoon when, despite the record-breaking downpours clearing, the muggy heat and humidity left the mood feeling unsettled. <\/p>\n\n\n\n

The Thrill of Riding: <\/strong> From the first-crank start, the crisp intake sound of the CVK34 carb, the low-end torque, and the overwhelming stability as the bike settles and stretches toward higher revs. <\/p>\n\n\n\n

Shop Owner’s Take: <\/strong> No matter how cloudy your mood, riding a perfectly tuned Ninja instantly clears your mind. All the reasons this bike has been loved for nearly 40 years are right there in your right hand on the throttle! <\/p>\n<\/div><\/div>\n\n\n\n

I made a flexible bracket using SUS304 spacers and round stock.
The wire length is also adjusted to spec.

Since the lever catches on an edge when lifted, adding a slight radius makes it easier to operate. <\/p>\n\n\n\n

I mounted it to the generator’s M8 bolt, so it’s rock solid.
The body-side attachment uses a threaded spacer. <\/p>\n\n\n\n
