After replacing the Exhaust System, I adjusted the carburetor.
Purchased for CVcarburetor setting.
I was using their Cabton and felt that the high rpm range was too thin, so I increased the Main a bit.
You don't have to change it, but if the high RPM range is thin, the Engine will be overloaded as well.
I've taken a safety margin and made it darker.
good point
● Easy to obtain.
It's cheaper than buying a Main jet from Rose.
Maybe it can be used for FCR Carburetor Body.
The Jet is made of Brass and has high accuracy.
A bad point
If you don't do maintenance and setting by yourself, you don't need it.
If you have a good exhaust system, you should increase the Pilot and Throw system for the low rpm range.
But I think you should make the Main a little thicker, in the high RPM range, because I worry about Touring, long time driving, and high altitude places.
Just in case.
