Well, I invested in an Aliant battery and after I placed it in the battery tray and made it fit snugly with the foam pads,I find there is a fit issue. The seat without having the plastic battery cover panel (which separates the battery from the seat), is making contact with the terminal. I have the terminals covered in electric tape and when I put the seat in its position and push a bit on it I can see the tape starting to rip. I tried the two different positions I can conjure to no avail. Is there something I'm missing? Bike's a 2014 R1 IMG_20161007_092035 by SurgeRR, on Flickr IMG_20161007_085633 by SurgeRR, on Flickr
If you mean just drop it on its side (from the pictured position) the problem will be getting the cables attached to the terminals, it'll be impossible given that position I think as the cables aren't really that long nor is there angle helpful.
I would make two extension bus bars out of aluminum rectangular bar and drill mounting holes at each end. Bolt bars onto battery then lay battery into tray on its side. Attach cables to top of the extension bars with nut and bolt.
Thanks for all the ideas guys, I'll look into modifying the battery tray and putting the battery on its side.
That would make it difficult for the cables to reach the terminals, battery tray modification is the only way.
