View Full Version : Split sportster tank

I was cutting into my friends tank to make it an oil/gas tank and it got me thinking. Has anyone ever run a split down the middle sporty tank? I think it could be cool and different maybe. Anybody?

I've seen a split sporty tank before, but I don't have any pics to prove it. I thought it was kinda cool. I always wanted to mount it similarly to how the old fatbob split tanks mounted. I say you should go for it.

That's a really cool idea that I've been thing of doing for years.

I've always wanted to do something like that but it sure would take away alot of fuel capacity using a Sportster tank. I guess using a king tank would work.

Did one for a friend years ago. Fuel capacity sucks but it looked super cool. We split it after welding up the fuel neck.. I moved the fuel neck and the petcock over to the right side and installed the 3/8 outlet on the btm rear of the left side. I put the return and vent line at the top front so the hotter oil would have to flow through the whole tank before getting picked up again. I ran ss hard lines up over the top of the tank which was black. For mounting we left them completely apart, one on each side of the backbone, leaving it exposed. Like I said it looked super cool but he couldn't pass a damn gas station and the tank would get pretty damn warm. You don't notice it under your ass but when its right in front of you, YOU NOTICE!

Awesome! Kinda bummed I'm not a pioneer but if I believed that I was I probably wouldn't have posted it on the Internet. Haha. That does sound like it could get warm, luckily it's my friends bike. I'm cruel I guess. Anyone have a way to get a few pictures? I was thinking of filling the filler neck and then widening the tank after its split about an inch to get more file in and to make up what's lost from side mounting it over the backbone. Just gotta find a tank to try it on now.

Google Arlen Ness ...Ness Cafe. Michael Lichter has some great shots of the tank on his site.

Ours looked almost identical to that except the oil lines ran over the top of the tank

I say , split it, run gas on both sides and make a cool oil tank to match.

That's what I was planning on doing. I have enough problems running out of gas let alone splitting it in half. That bike looks sweet though! Just gotta find a tank!

Fab Kevin did one too

It would be a good way to get full fuel use without going the Frisco route. Hmmm......

My 77 ironhead had split tanks on it when i bought it.

Has anyone taken a sporty tank, split it, welded in a divider, and then welded it all back in to a one piece tank?

On the old time fat tanks the oil bag was kind of a shell that covered the part of the fuel tank that stuck through the frame.
Half & half? Maybe on a 2-stroke. Think asymetrical. How fab are you willing to go?

Yea, done it...looong time ago in a land far far away....bout 6 or 7 years ago i think
