T-REV α System CB400 SF / SB

T-Rev optimizes the internal pressure by controlling the blow- by gas. It creates negative pressure in the crank case and makes the piston and crank shaft movement super smooth. Definitely can also feel that the engine braking become more gentle.

Engine braking works properly.
It's so much easier to ride.
The installation was done by Motorcycle Shop.
He said it was really Large strange.
I don't know how durable it is yet.

I have been interested in decompression Valve for a long time and was considering including products from other companies.
Regarding purchase, other people 's imp are changed to Large change reference. I finally decided on T-REV α as having decided exclusive setting for the car type, thing becoming cheap at Sale became decisive.
As for the installation work, because it is a narrow Space, it is hard to get into hands, Plug cord, other Harness sorting out and piping is not handled and it will not fit with chitin so it was Large strange. (Periodical maintenance becomes depressing)
The attached manual is difficult to understand! I thought that it would be nice if there was a little detailed explanation.
Regarding the effect after installation, starting from Idling during Start, you can start with half Clutch without raising the rotation and the rise in lightness has also become lighter. As for Engine braking it became pretty Mild and it almost got no more gory shaku. I felt quite an effect in trial operation so I am looking forward to the future Touring.

Before installation it was quite troubled with donkei?. Because I changed the motorcycle, I thought it would be fine if I got accustomed for a while, but I did not resolve it unnoticed, but consulting my acquaintance, I gave up halfway that the modern machine is quite such a thing. However, if you look at the explanation of this product, it is precisely what I was worried about will be alleviated. Because the price is expensive as it is, I hesitated much. I worried further about the season in, but decided to purchase. I carefully read the attached instruction manual with the attached attachment, but it worked but I felt like entering this kind of work. I think that installation is okay if you can work with plug replacement plus α. The result was fitted correct answer? It is lightly lifted and lightly donned is reduced, embrah is also easy to apply and it is satisfactory. I think that fatigue will be alleviated. Although the price is high, it is a product that can be recommended. Mr. Webic, try discounts hard, lol

I installed it by myself this time because I was able to feel the effect by attaching it to Grome before half a year ago.
At the time of Grom, it was able to be done in about five minutes, but this time it was really Large strange.
When the installation was completed and I looked at the sky a little, I felt that it rushed very lightly.
After trial running the next day, I could hardly feel the vibration of Rear Sets.
I feel that the sound of the engine has also become quiet.
Engine braking is also Mild.
Always went to a pass that runs Always 4 / I was able to run at the 6th speed where I am driving at 5th speed, I thought the rise of Torque was amazing.
Axel opening degree when cruising Bypass is reduced, you can expect fuel consumption to rise in Touring.
Also Torque had risen considerably and the rise improved
At the intersection Left When folding like usual, Rear tire suddenly slipped, this must be careful.
