Ok,, if i put on a filter, what do i need to do to the jetting? just adjust the needle? same for pipe.. what if i add both, are there fuel issues?

I removed the spark arrestor and added a K&N filter on my fiddy. At first I raised the clip on the needle 2 notches and it was better but not great. Then I went from the stock 58 jet to a #61 and put the clip back in the stock position. I feel its about as good as its gonna get. It runs strong but I do feel like I lost some low end grunt

. I don't know how to explain it since the fiddy really only has a few HP's .
