98 fatboy running terrible
I have a 98 Fatboy that I just installed a stage 1 kit .
It has vance & hines short pipes on it which were on it before the stage 1 kit.
Now the bike runs fine on upper end but a low speed it backfires and runs terrible.
I thought it was ruuning lean so I tried a bigger pilot jet but hasnt helped much.
Any ideas would help.
Thanks
