Hey guys,new to Harleys and own a 2003 Low rider with 300miles. It sat for 4 years. It used to cough unitl i installed the HD kit, jets, meter rod, idle screw. And performs well. It does not cough now but gas milage is only 20. I can't believe thats right. It also stalls coasting to a stop after a cruise. i have some thoughts but welocme experienced opions. I use 89-91 octane

Thnak you!

 

Something's not right here. You should be getting around 40 mpg.

 

Does the bike have a high flow filter and pipes?
May be too rich causing flooding and stall.

Option: Remove needle and replace original however, use two needle shims. You will have to readjust mixture.

 

Yikes ya something's dreadfully wrong, even 30 mpg is BAD for a H-D so 20 is disastrously bad...

 

Thanks, stock exhaust, stock filter. have K&N to install next week. 46 pilot jet 190 main. gas milage the same with stock needle, and jets. coughing is gone now. i am thinking enricher issue or possibly float or maybe sucking fuel thru vacumn for pump/ Any thoughts on common issues would be appreciated. I am going to do some test next week.

Just thought some one here may have had similiar problems

 

On my 02 Heritage Springer with carb and stage one I was getting about 35-38 mpg.
