I like the comment about "Intercontinental range" with the Yamaha Fuel Tank! lol
It should go a couple hundred miles anyway.

I have a Yamaha tank like yours, along with the rest of the Yamaha. It came off a vintage enduro bike. The tank might be a challenge to mount since it requires channels on the frame. The rubber cushions at the front of the tank tunnel slide into the channels to hold the tank firm. The rear of the tank is held down with a rubber retainer. I have used large "O" rings on similar tanks. The tank holds 2.5 US gallaons. Is your tank clean, does it have a petcock?

It has slight rust. I will clean it out. The petcock is on it and turns freely.
I think I have the mounting figured out. The rear tang will accept a U-bolt from the frame easily, and I can use some pipe insulation or a pool noodle float to make it fit the frame. Then I am thinking about basically tying it down with a leather belt for a kind of vintage hot rod look. If that doesn't work, I found out that a good friend of mine is a talented welder tonight and is willing to teach me!

I once mounted that style tank by cutting two 2'' rings from a pipe of the correct size and welding them to a crossbar that in turn welded to the frame. Two rubber caps slipped onto the rings made it snug and secure just like a factory mount. The rear used a u-bolt like you describe.
I think this would work quite well for a bicycle mount. Sorry no pics as it was back in the early 80's and camera phones didn't exist yet.

I think I will pull my tank off tomorrow and do a test fit before I spend too much time cleaning it up.
What do ya'll think?
Looks like the big tank is actually pretty fond of that smaller tank if you ask me...LOL!


Seriously, I think that tank will look ok on there once it is in place, it's a big rascal but you should have a long distance runner with that one for sure.

Peace, Map

I shortened the pipe, machined a new exhaust mounting bracket and clamp. The clamp came out so nice I machined new engine mount clamps to match the exhaust clamp. Went for a test ride, about 6 miles round trip to Wet Lands Park in Henderson, NV
