I would like to raise the front of my fuel tank about 3 inches to show more of the twins. Has anyone done this and is there any problems with the EFI fuel system that you would know of?

 

I raised my tank 2", no problem with EFI, but your gas gauge becomes inaccurate.

 

Make sure your bars and signals have enough clearance if the signals are still mounted on the bars.

You can find tank lift kits on ebay, but as Drew suggested make sure you have the clearance. I wouldn't have the clearance with stock turnsignal placement.
I have a two inch I need to check to make sure it clears my new bars, then paint to match.

 

No problem with EFI...but you will have about 1/3 gallon less usable fuel capacity with a 3" lift.

Here's a quick way to check for clearance issues-

1. With bike on kickstand, take the bolt out of the front of your tank.

2. Loosen (do not remove) the bolt at the rear of your tank.

3. Turn your handlebars all the way to the left and raise the tank up 3 inches to check for clearance issues.

4. Turn your handlebars all the way to the right and raise the tank up 3 inches to check for clearance issues.

Do you actually lose access to the fuel, or does it just make your gauge inaccurate? I asked this question of the guy that made my lift kit and he said it just makes the fuel gauge show that you have less fuel than you actually have.

Curious to hear your thoughts...

 

Raising the front of the tank also raises the pickup, cause its up front too.
So you loose the use of whatever amount of fuel remains in the tank 'below' the pickup.
At 2" your going to loose about a quart or so.
The fuel gauges are notoriously inaccurate to start with so there's not much of a loss there.
Your just going to have to rely more on the trip meter, after you figure out just how far you can go, if your not doing that already like the rest of us.

 

Interesting, thanks. I'll have to take a gander at the service manual to see if there are any diagrams that can help me see what you are talking about.

 

As Citoriplus said, a tank lift raises the front of the tank, effectively putting the rear of the tank in a lower relative position. Since the fuel pick up is NOT at the very rear of the tank, some of that fuel at the rear of the tank becomes unavailable to the fuel pickup. (unless you're headed downhill )

Depending on the size of the tank and the height of the tank lift, anywhere from a 1/5 of a gallon to 1/3 of a gallon is lost in effective fuel capacity.

What the guy told you is mostly correct also- your gauge will show less fuel than you really have in the tank, for the same reason stated above. But it does affect usable capacity.

This is a non-issue unless you make a habit of running the tank to near empty.

 

great mod, did it to my deuce and love it.. check and adjust your handle bars if your raising it a full 3". i raised my 1.5 and didn't have to relocate anything...
