I thought air cleaners restrict air flow. I have never had a air cleaner on anything I have raced.
I went back to back runs a few years ago with & without air cleaner. Absolutely NO difference. And that's a drop base with a 3" element.
Like I said in the air cleaner post... did you
re-jet to see if it really does change(performance)..
I know for FACT that any air cleaner is a restriction
so a jet change is required.. its just a matter of how
much of a change and what filter you were running... I
flowed so many air filters it gets BORING.. with and
without adding fine dust to it
