Sounds right to me. I was figuring on losing a few miles to the tank. I've never understood why they don't make the petcocks sit at the very back of the tank and why they wouldn't pitch the tank slightly anyways just for efficiency.

 

My Fuel Gauge reads like that right from the factory. It's way off. I always use my trip anyways.

 

I think it makes the bike look 100 times better, but on a wide glide, i had to rotate my bars forward and adjust the brake and clutch levers. it makes the handlebars feel a little uncomfortable compared to the stock position as it makes the angle bend more rearward than down which is unnatural bend for the wrist. I had to do this or the throttle cable was rubbing the tank when turned to the right.

also, on a wide glide, the fork clamps on the upper triple tree misses the tank about 1/8 of an inch at full turn with a 2" lift. if i ever drop the bike, im sure there will be enough force to make the triple tree punch into the tank.

with all that said, id do it again.

 

The reason most people do a tank lift is for the looks. When we first started designing ours, we did so for 3 reasons:

1. The looks... It just flows better with the lines of the backbone of the bike to be lifted.
2. Ease of cleaning.... With more of the rockers exposed, it is now easier to clean them.
3. Air Flow... It makes for better Air Flow over the motor.

After doing testing, it was noticed that since more air now flows between the tank and motor, in some cases it can reduce the buffeting. This is not what they are designed for, more of a "side affect".

There is tons of information on tank lifts in this thread:

In that thread it also addresses the fuel gauge and usable fuel capacity when you do a tank lift.

 

X2= More AIR FLOW!!
the fuel gauge is an easy fix if you want to even be bothered

Even when my bike was completely stock the light comes on early. I'm pretty sure they do this so you don't run out. When the miles to empty says "LO", I still have about 1 gallon left. This is your reserve. The analog gauge (which most vehicles have not just bikes) is never precise.

 

I did a 2" lift on mine. Much easier cleaning, and I have less wind hitting me while riding. 09 street bob.
