After all, these are borrowed parts that you can’t really understand until you try them in person.
Nobody wants to take unnecessary risks, right?
But if you want to create your ideal machine,
you have no choice but to step into the unknown grass.
Well, I recently got the registration sorted and have been cruising around town, but…
it doesn’t have the same thrill as the Zephyr 550.
To put it nicely, it’s wonderfully easy to ride; to put it bluntly, it’s bland. That’s the GPZ 550 for you.
With the half-fairing and a higher-speed final gear, it has the feel of a lightweight long-distance tourer.
This time, I want to focus on one thing: a low throttle! THE classic bike
throttle that requires you to twist your wrist so much. I want to improve that.

THE classic bike (*´ω｀*) – reminded me of the stock GS1000S
When I marked it with a marker and looked closely, I found I was twisting it nearly 90 degrees.
With 550cc, that’s basically full throttle.
Since I have to twist my wrist that much every time, it gets a bit tiring and sometimes I can’t open it fully.
I want to be able to open the throttle fully without hesitation, so I want to increase the winding diameter and convert it to a high-throttle setup.
Of course, “increasing the winding diameter makes the throttle heavier.”
Vacuum carbs are already light to operate, so this is definitely a benefit.
Since I wasn’t sure what would work, I prepared two options.
I prepared two sizes: 34.3φ and 36.5φ.
The throttle cable only has an open side, so I can only use one.
The throttle cable inner should have some slack.
The stopper on the switch side should be properly seated.
When the handlebar switch is fixed, it should operate smoothly.
If you don’t check these things, it gets super dangerous, so be careful.
I got greedy and installed the 36.5φ first, but when I fixed the handlebar switch, it didn’t operate smoothly.
It seems to be catching somewhere, but it takes time to check, so I’ll skip it for now.
The 34.3φ operates smoothly, so I want to test that one first.

A few degrees of difference should make a dramatic change (*´ω｀*)
It’s become a bit more high-throttle (*´ω｀*)
I think the acceleration feel is quite different already.
These small improvements let you focus on just riding and enjoying the bike.
It’s not all about expensive parts;
first,
“squeeze everything out of the stock setup, and only then seek changes if something’s lacking” is a good approach too.
Probably with the stock 27φ TK carb, the 36.5φ throttle would probably be more fun…
But this isn’t the final form since I have the Zephyr CVK30φ coming up next,
so I need to keep the throttle sleeve as a tuning part.
Hey, if your throttle cable play is all loose and sloppy!
Just adjusting that alone will change the acceleration feel quite a bit, I think.
