fuel injection/pump problem?
New to me 2005 Vegas (my first ever Victory, so not very familiar with them). The only upgrade I am familiar with on the bike is it has the Stage 1 Victory Performance Pipes. The bike has 12k miles and I have cleaned the throttle body already. So here's my issue: When the fuel falls to under half a tank, or I get around 90-100 miles ridden on a tank, the bike really sputters while at idle, like it is struggling to get gas. Once I get going its fine. But if I'm sitting at a stop light, I really have to rev it and over-rev it to get going or it will stall out. Full tank of gas, no issues. Again, it seems to occur when I get to under 1/2 a tank, or around 90-100 miles ridden.
So I'm thinking I may have an issue with the fuel pump and/or injectors? Or does anyone have any other suggestions on what it might be?
Thank you in advance for any help.
