In NORMAL, it seems that the Gas exhaust is limited and the Gas exhaust is thin.
So Nozzle changed from 10 hole to 12 hole and it is expected to Torque up from low speed with Smooth Gas emission.

Barrel the Exhaust System when replacing the Nozzle4 Remove the Pig Nose on the Intake
AI Cancellation Blowby gasTube and One-Way Valve installation were done at the same time;

Acceleration improvement and low speed torque up effect are …
Brushbo or something?

I changed a lot of things this time, so I don't have much experience, right?
Exhaust System Replacement Pig Nose Removal AI Cancellation eliminates the low speed torque and makes the high rpm smooth.

Helpful?

I'm glad we switched.

After replacing the exhaust system, the low to mid RPM response was eliminated and the car started to run better. I was very impressed with the effect of the replacement.
The replacement process was done without Trouble in about 30 minutes with the help of reports from experienced people. Thanks!

I put in an external exhaust system and had a stall disease
Introduced
As for the installation, everyone says the screw is too hard and the screw licked, but I managed to get it with Impact Driver
As for the effectiveness, it is outstanding It doesn't stall It doesn't stall, and the gas mileage isn't much different, so much so that you only have to release the clutch to get going

This is the injector you need to bore up a Klx250 to a 300cc to wake up the bike. No need anything else like ejk or power commander, it will work fine without it. But if you wanna add those piggy back ecu, they will work too. We tried ninja, er6n injectors, they don't fit and don't work. This is the perfect solution for efi conversion. Now the bike is power.

Great!

D-TRACKER-X is squeezed for Gasoline and air
So, I changed the injector to this one, and I thought I could get a lot of power up just by removing the lid I think I am comfortable with the various senior people practicing the installation

After that, change the exhaust system to one with a better venting system if possible
And if you want, you might be happy to install a sub computer as well
