Gas tank fitment

[bosco659]

Will a gas tank from a ‘79 fit directly on my ‘76? How are the “Yamaha” emblems attached? Thanks

79's used dual vacuum actuated petcocks which have a different hole spacing than a 76.
79 tank badges were secured with 2 small screws on each side . The "Standards" have holes on the same horizontal plane while the "Special" badges had an offset (vertically) plane.
Which 79 tank style are you considering?

Having mounted both a "Special" tank as well as a "Standard" tank on this 79 Special II it is clear that those do interchange.
I do prefer the "Standard" shape however.

a 79 Standard tank is a very good find in my opinion.
A very likable color and stripe.. looking for a pic...

They will swap........ All tanks from 74-84, (Standard and specials), are a straight swap. What you will find is the petcock area is different between the 76 and 79 standard tanks. 76 tank has a bulge the petcock sits on. The 79 is flat. this because the vacuum petcocks protrude further out from the tank, in other words, different height between the Manual and Vacuum petcocks. Not a lot of room between the tank and carbs...............79's are nice tanks and look great as the colour changes in different lights, the thing is the badges have a habit of is fading and are don't keep a good look, as in bright and shiny. Can be painted. Probably best to do as to buy a set can cost as much as the tank

Here’s the tank I found on Facebook Marketplace. $350 located near Pittsburg, Pa. if someone is interested I can send a link. Looks super clean inside as well.

All indications are that's a Special tank. If the paint is that nice, it needs the side covers with it to command that kind of money.
