500 LTD very low mpgs :(
2003 500 ltd 23,000 miles
I took her to a crappy mechanic for a bunch of stuff, and the bike returned with new symptoms. Took her back to him TWICE and still had the symptoms, so I definitely have to work my way through this one by myself.
"work done" Complete carb cleanup, carb sync, 17 tooth front sprocket ( up 1 tooth from stock), adjusted chain slack.
The bike returned with a terrible miss which turned out to be pilot screw adjustment. I ended up drilling the carbs myself to access the screws ( bike is my MAIN mode of transportation to school, so I can't just wait around) and tuned the bike to get rid of the miss. The problem is I used to get 45-48 mpg city driving with stock sprocket, dirty carbs, etc.
On the last two tankfuls I've NURSED the bike all the time, keeping it at 55 mph on fast streets, smooth shifting, no racing, etc. And all I managed to get was 40mpg on first tankful and 41 on second.
Can the pilot screw adjustment be off and screwing over my mpg's?
Tire pressure = 40 psi front and back ( front=Pirelli Night Dragon, back=Shinko something)
Mods = K&N air filter, Harley Dyna mufflers with the center thing punched out ( you can see right through the muffler). These mods have been there for over a year, this began 2 months ago.
Thanks in advanced! Other than the mpgs, she rides great, idles great, etc. I use sea foam every other tankful too.

16,484 miles when I bought it September 2011. 29,100 miles January 2014. All these miles have been enjoyable almost entirely thanks to this forum.
