What about the fuel filter ? Or the idle speed control

Expert:  Steve replied 7 months ago.

ok......what did the spark plugs look like that you took out to put the new ones in?

what kind of gas mileage are you getting?

what is the idle rpm when the engine is warmed up?

tell me everything you can.

Steve

Customer: replied 7 months ago.
I don't know the mileage it's not that bad I just noticed it. But not likes its real bad . Sprak plugs looked fine
Customer: replied 7 months ago.
Have no idea what's the idle rpm?
Expert:  Steve replied 7 months ago.

the most common cause of your problem is when people turn down the idle rpm because they think it makes the bike sound cool, but the engine is unable to idle reliably if it is too low.

set....or have someone set.....the idle rpm to 1,000 rpm.

let me know if you need more help.

Why are you trying to direct me to? What are your thoughts ? What are your reply to what I asked about those 2 parts
Customer: replied 7 months ago.
There is a set screw that is by the air filter that I kept turning different ways to get the idle to go up ? But it did not make a differance ? Is that the idle rpm?
Customer: replied 7 months ago.
The bikes been running fine this had happened just the last 3 months
Customer: replied 7 months ago.
I have to take it to a dealer ? To do that idle rpm to 1,000 ? That would cost a penny
Customer: replied 7 months ago.
When I turn they screw with a hex wrench which way should I go?
Customer: replied 7 months ago.
To the front of the bike righty tighty lefty loose Y ??
Expert:  Steve replied 7 months ago.

your other option would be to purchase the equipment required to set the RPM per the service manual, as well as a service manual, and perform the maintenance yourself.

the allen screw you have been turning is for the cold idle speed. NOW.....you need to have the dealership set your cold idle, as well as the warm idle rpm.

Steve

Customer: replied 7 months ago.
One last question I was told to do that when the bike is warm the idle speed . Where is the warm idle speed ?
Expert:  Steve replied 7 months ago.

HOW are you going to adjust the warm idle speed if you have indication of RPM?

the specification is 950 - 1050 rpm.

Customer: replied 7 months ago.
I wasted 28 bucks for this texing ? And now have to pay 120 a hour at Harley ?
Expert:  Steve replied 7 months ago.

I opt out.

best of luck.
