Last year I finally started to fine tune.Started jetting up with plug readings using the azz dyno and time slips.Only getting 4 runs in a day made it a loooooong process.I ended the season with the biggest jets I have which are 99's and its square and still a little lean.My carb guy said to start reducing the air bleed size.
What I would like to know,what is the difference between increasing the jet size VS reducing the air bleed. I can see where I might be able to make small changes due to the DA with air bleeds only.Is that ok,,or should I be making those changes with jeta??
