The 4.5 isnt a peanut tank at all..... it is more of a bubble lmao

the peanut tank is the

2.2 (48,72 model sporties)

the 2.5 (1985ish-1995ish sporties)

and the most common

3.3 (1995ish- present) sporties

Oh ok, when I reread it I realized that.

You got the tach,,use it,,
In the city use a bit more rpm and a little less low end torque.
It worked for me.
when i got it, 33 city, 42 hiway
now 38 city 49 hiway and I ride fast on the superslabs.

Your EFI Roadster is more efficiant above 3,000 rpms when
accelerating,,4,000 is even better.

When going for big speed shift around 5250 rpm, and shift fast,
Use that tach.

with the 883 im pulling right at 58-60 mpg. with the 77 xlh she gets around 40 with the 2.5 stock peanut on her. makes for some gas stops. ( got a 3.5 king tank to help her out ) if i get off my lazy butt and get back in the garage .

I got to bite. Is this high RPM real or BS. I keep the RPM low unless I am on the freeway and am getting around 40 ish MPG. So if I wind her up a bit through the gears will I see an increase in mileage?

I'm with Mad Dog. The fuel system squirts X amount of gas every revolution. X x 3,000 < X x 5,250.

The high RPM deal only works on an engine with smaller pistons. For instance an 883 running at 4500 rpm will get better gas mileage than a 1200 running 4500. Running low rpms equals better gas mlg unless you are running at 30 mph in 5th gear and pushing so much fuel to get it up and going. running low rpm in normal conditions will equal better fuel economy than running high rpms.

Carburetor or F.I. the amount of fuel is dependent on both RPM and load. Lightly loaded equals less demand equals less fuel. F.I. being better at it than carburetor, but still that's how it works.
