Looking to replace Tank

[CanadaDan]

I want to put a different tank on the 77 GS400... nothing wrong with the stocker but it's kind of boring and I want to cafe this bike... full frame off next winter.

I really like the look of the more angular GS450 tank... I think it's the 83 E? I have an oportunity to pick one up for $50 in good condition but I just want to ease my mond before I bring this thing up to Canada.

It LOOKS like it should bolt right on... same front and rear mounts... the petcock looks the same too... has anyone tried this combo? The only thing I am unsure of is the length of the backbone for these two bikes... still waiting on measurements from the 450 tank but curiosity has no patience

Any insight would be appreciated!

My understanding is that they they used that tank on the E model in '80-'81 in the US. Not sure about anywhere else.

Dan..
It should be a direct fit....only thing will be that you will see a lot more of the neck at the frame. You might have to re-route your wire harness and hide it a little better.

Good luck

I plan to eventually build a custom gas tank for my 550LX, if for no other reason that I despair of ever finding a fat gas tank like I want in the aftermarket.

With my Dual Headlight Conversion, I'll have ample reason to help cut the air around me by widening the tank in front of my knees. I'd also like to make it a little taller so I can install a stock filler neck and my original locking gas cap along the centerline, not offset to the right. I'd also like to bring it down a little to hug the frame better, even if I have to install a heat shield between it and the engine. Better contouring for my knees and inner thighs. I'm a fat woman. I demand my comfort where I can get it.

All in all, I'm hoping for a look that would fool a novice into thinking it's an OEM Suzuki part and making it look like it always belonged on this bike, but I want a capacity boost of over 100% to about 8 gallons. I'd like a range of about 400 miles. Yes, I'll prolly be adding a gel seat too. Iron butt's meant to be a figure of speech, not a literal description.
