Not Ranked
I have tried the 55 idle jet with the current set up
40 choke
100 idle
55 idle jet
210 air corrector
f7 tube
160 main
55 bypass
the smell of the exhaust is great, however I get popping thru the carbs and leaning condition.
I open the mix screw 1/4 turn to make it 1 3/4 and it was a little better but still needed fuel.
I replace the idle jet with the 60 and back down the screws to 1 1/2 and it runs alot better.
According to the article it suggest that you should change the main jet. I will give that a try.
According to all the books the etube should only be changed on a dyno and does not make much of a change.
If the f7 is the riches tube bottom RPM what etube are you recommending.
Is there a chart that list all the tubes from rich to lean or vice versa.
Suggestions please??/
