A Bit of “High Throttle” Works on Mid-Displacement Zephyr 550 Daytona FLAT Throttle Sleeve 29470

Mid-displacement requires a lot of wrist twist!

You shift a lot, and compared to big bikes,
the throttle
“won’t run unless you open it wide,”
which I found

subtly annoying on mid-displacement bikes.

Larger throttle sleeve outer diameter =
more cable wound up = high throttle
This should make things a bit easier, right?

It increases the winding diameter to approximately 36.5
φ

The larger this outer diameter,
the more “high throttle” it becomes.
With a high throttle, the throttle feels a bit
heavier… but

since it’s the stock vacuum carb,
it doesn’t feel that heavy.

Daytona is
always excellent!

Daytona FLAT Throttle Sleeve 29470

I’m going to repurpose this one!
It’s used on ZRX models and Z900RS

The winding outer diameter and other specs are listed,
and that’s so like Daytona! I’m grateful every day.

Before replacing,
I mark
how much

opening there was

Knowing this
“makes the change much more rewarding.”

The throttle cable inner length is important!

Reset all the throttle cable play adjustment,
then install it.

“Confirm that the play is taken up.”

Thankfully,
the inner length had plenty of room.

I’m
the type who doesn’t use adhesive

Using adhesive makes removal
“a pain,”
and it often doesn’t hold securely.
Next time for grip replacement, I’ll clean first,

and I solve
that stress with 3M non-slip tape.

This is the thinnest and leaves the least residue.
Once applied, you can replace the grip
repeatedly.

Of course, the tape does make the grip
slightly thicker, but it’s

within the margin of error! The work and grip feel are stress-free!

It’s become
a bit more high throttle!

By the way, even this small difference
“makes a huge difference.”

Unlike big bikes, mid-displacement bikes
constantly open the throttle
nearly all the way.
This small difference × number of times = a win?

If you minimize stress on your motorcycle
and focus on riding,
both safety and enjoyment increase.

Alright! Let’s go for it!
