my 05 electraglide andrews 37 cams, hydraulic tensioners, power commander, 2 into 1, 95" upgrade, 5 speed trans, I treat every light like a 1/4 mile my bike is loaded with crap extra passenger most of the time I am less than 30 now. we did do a mellow really loaded trip where I got 37 mpg ain't seen that since. We had so much camping **** tied on I rode like a nun. I haven't been able to keep my driving to a safe or normal enough level to do another calculation since then. light turns green and I am gone baby.

 

I get about 48mpg with my 95" and SE 6speed and hydraulic tensioners on the highway at 70-75 mph.But the biggest difference were the smiles per miles.

 

I get about 34-36, on a good tank I've hit 38. Daily driver,51 mile round trip per day. With the 88 I was getting 42-44. As I stated in another post I almost regret doing the big bore.... Just alot of problems.
Went from home to Phoenix and back, about 450 miles, a few weeks ago and got around 34.
510 S&S w/chain drive, valve job and "carb work".

 

I've put 20,026 miles on my 95" build.

I've used 484 gallons with an overall average of 41.61 mpg..

 

'03 Fatboy carbureted. About 44 MPG when it was stock. 95 BB 204 cam - average about 36 MPG.

 

Between 40 and 42.

Carb; S&S 510 gear drive; V&H exhaust; and, K&N air filter.

 

50-51 MPG average mostly highway miles as long as i don't run over 70 MPH. Live in rural area mostly. Mileage does count when gas is over $3.00 per gallon.
