I changed my racer replica that had cross transmission and back torque limiter to ZX-9R. I noticed that the engine brake force during down shifting became stronger, and I decided to install an inner pressure control valve. I wavered over T-REV, but I chose this REDUCER because I read that it was more effective in someone's blog.

It is easy to install. Just remove the tank and cut the code that connects the crank case and the air cleaner box to install (You need to be careful not to mistake the orientation, though).
I first thought of taking off the entire part and cut it, but the hose at the crankcase side was stuck and didn't come off. So I had to use a cutter to take it off and install this valve. (The cut edge of the hose isn't neat because I had to do this in a cramped place.) If you want to install it neatly, you better have a new hose.

I knew that it was going to work all right, for I've seen a similar product installed on a MINIMOTO Single Engine. But with 4-cylinder engines, the effect wasn't that apparent as a single engine. Still, the engine brake had become weaker. You may get irritated at first because it won't slow down in the same way even if you apply the same braking force.
The jerky feeling you get when you raise or lower the shift has been reduced, but you may need to apply braking more securely than before.
Also, I now can easily start my bike without thinking of the rotation number now.

These type of products are promoted as it has no problem, but I cannot recommend this item to those who drive the bike on street roads or touring drive. It's probably better for those who use their bikes on circuit courses or on mountain roads. View detail
