I have a 1984 XR1000 with the stock ~2 gallon tank. I need to switch to a larger tank. My question is, Is there any compatibility issues with other sportster models from that era (like the 82-94 Sportster XL)? I was looking at a King tank like this one http://www.ebay.com/itm/HARLEY-SPORT...220900&vxp=mtr but their compatibility chart shows it doesnt fit the XR. So what are my options? Will a XL tank fit or will it require some modifications? Is there a difference in the XR frame compared to the XL?

 

Welcome to the forum , nice bike BTW.
How big do you need?
Is 2.9 gal enough?

This shows an exact fit for your bike.
I don't know the difference , I'm sure others will chime in.

Hi from the UK and welcome to HDF. An XR1000?! We need to see pics. In the meantime our experts will call by soon on your tank question.

 

yea post pics, I'd love to have an XR1000

 

Any Sportster tank that fits from '82-'94 should fit fine. Ones made to fit '95-'04 have the mounts in the same places, too, but have rubber grommets in the mounting tabs.
