Carburetor setting is the first place to change
The external Exhaust System has a good release, so the Carburetor setting will gap with the AfterFireA and Idling instability at the time of embracing.
In the case of Normal cab, it is recommended to increase the speed of Pilot Jet for Large cab. 。
good point
It is easy to narrow down the setting because it is the number that is used realistically with 40, 45, and 50.
If it is an external exhaust system, it settles around 45.
The quality of Brass is not bad, and the accuracy is good, so it is easy to install and replace.
BackFirea is gone.
A bad point
Carburetor setting may be difficult for those who are not used to it.
When you hear "Carburetor setting", you tend to think "Main jet", but I think it will work well if you start with Idling and Pilot setting which controls low RPM.
The carburetor setting will change as the exhaust system is changed or aged, so it is better to have Pilot Jet.
