A sound that evokes the good old Showa period.
The MAJOR Short Tube is an old car-style custom exhaust system with a Showa-era sound, appearance, and appeal that is still very popular today.
With the popularity of the East Ribeye and other models, there are more and more opportunities to see vehicles with Short Tubes on motorcycles ridden by the younger generation.
What is Short Tube? ‥
Basically, it comes from the old Racer.
In other words, when cars were regulated without silencers, racing parts were used in production cars or were given a look-alike appearance because the performance would be improved if a set was added.
Performance and characteristics
The sound is Large and the low-speed Torque is weakened. The sound is Large and the low-speed Torque is weakened.
The lower exhaust pressure makes the start of the system feel slower.
Torque is obtained by utilizing the exhaust pressure of the engine. 。 If there is no exhaust resistance at all, the Engine will turn lightly 。 → On the other hand, there is no resistance (no snagging) → the low-speed Torque is eliminated because the exhaust Gas flows as it is.
Exceptions are...
Short Tube, such as MORIWAKI and YOSHIMURA = JMCA Certified Exhaust System, looks like a Short Tube, but its internal structure is completely different, and it has a device to suppress demerit while producing merit. 。 Torque is lost to the extent that such things are installed.
Short Tube Intake Setting (Torque shortage cover method)
● Fueling to compensate for the lower Torque.
→ low speed range Raise the Pilot or Slow Jet number. The fusion point of squeezing out Power by turning to high RPM and at the same time applying Torque at low RPM to go around the Corner is the so-called Setting." It is a thing called 。 Short Tube not managed by Torque." The reason why the motorcycle that was made to be a "3.0" is revved to a very high rpm at start or acceleration is because "it would not go forward otherwise".
It is because it is "Motorcycle without Motorcycle".
In a youthful indiscretion, I put this on my ZEPHYR because I wanted something inexpensive, cool looking, and with an austere sound (laugh) &arrarr; Now I regret it (laugh).
good point
◎ Inexpensive. At the time, this was Mast (laughs).
◎ Sound. To describe it in words, bobbing → blowing with Idling is a fawn (lol) The sound when the Engine is turned is pleasant.
◎Installation accuracy is not bad for the price. Easy installation.
◎The appearance is good.
◎ Not only ZEPHYR, but also many air-cooled 4-cylinder lineups.
A bad point
The sound is too loud to pass inspection. 。
Center Stand cannot be used due to the mounting position.
▲AfterFireYa started to go out at low and mid speeds, to the point where the Engine was jerky and un-runnable as if it was Knocking. Carburetor setting to compensate for the low-speed part eliminated the problem.
Rust-prone.
The welding of the ▲Bracket section is unreliable.
Baffle removal is rather tight and difficult to remove.
In other words, putting a Short Tube in the modern era is the old Racer style! 。 According to the theory of exhaust system construction, a short exhaust system tends to lack low-speed torque because it is unable to accumulate sufficient exhaust pressure.
Many of them will not even be muffled properly. 。 There are many different Muffler makers, so it is hard to generalize, Short tubes are a type of tube assembly that are characterized by their wilde sound, which helps to create a badass look. Many of them have too much openness, so they tend to lack low-speed torque. Can we say?
But I digress...
Q:Why doesn't a pure Racer, with no sound restrictions, have a Super Short Tube? Or not remove the Exhaust System?
A:It only increases rotation when exhaust pressure is removed, The power to kick the ground. Because there will be no more 。
The appearance and sound of many Demerits are appealing, and if you are thinking about purchasing one, please take into account that the act of customization = self-responsibility.
I think it is a decent product for the price.

Size is not right, so I stopped using it.

Outlet or B-grade? Defective?
Gari Wound in a prominent place when the packaging is opened.
Repair and install because of the hassle of returning the product.
It's a shame because the design, volume, and cosmetics are not bad.

Bean-jam-filled wafers (Monaka) wobbly part (e.g. of a video game)
Due to the low price, only things arrive with a bang.
No Instruction Manualetc.
Bean-jam-filled wafers (Monaka) The tube and the steel tube part are Rivet fastened, but it arrived in a wobbly condition.
It's wobbly enough to move by hand.
Bean-jam-filled wafers instead of baffles (Monaka) The part is wobbly.
I wrote something similar before in Impression but for some reason it was not published. What do you mean?

After all, if you compare it with MORIWAKI and YOSHIMURA…
After all, it may be impossible to make a collective tube except for YOSHIMURA and MORIWAKI.
I bought it because it was cheap, but I couldn't hope for performance just because it was Mischief.
good point
Cheap.
It looks good.
A bad point
Torque drops to Large width with a blast.
Carburetor setting collapses like Large.
Heat-resistant paint is easy to remove.
He'll think I'm a mischief-maker. 。
I think it is suitable for people who are longing for old car association.
It's just not for me.
But it's cosy and the shape is Parenthesis good, that's the charm.
