homemade 43l tank on BMW K75 max 70cm wide, what do you think ?
"You plan to take the gasoline out of the wasteland. You sent out two scouts to find a vehicle, a rig big enough to haul that fat tank of gas. What a puny plan..."
Well done Mudbreeder, nothing annoys me more than motorcycles with small fuel tanks. I hate having to plan my road trips based on where I can find gas stations. Looks like you have a nice inventory of machinery and tools. Now just get it sprayed and shiny so it can look pretty. Is the right side a reserve tank or did you just punch through the original tank?
in fact there are 3 separate parts, the side tanks are welded to the original tank, below the top welding are some holes for the air to pass through and fill up, on the bottom they are connected with tubes so i can shut 1 or 2 parts off if i should fall and have a leak, the fuell pump can be mounted in 2 positions
I'll add some pictures from the start:
Great work so far - don't forget to show us the finished product.
Did you add any baffles inside to help strengthen the tank??? Also this will help it retain its shape when it expands and contracts due to heat and cold. This in turn will help stop the welds from cracking.
Might want to research how much stress that 43 liter of fuel would add to the frame of your K75.. though I've never head of a K75 frame failure..
Bet you could sell wooden ones to the KLR guys.
I think if I had the shop skills you have I'd do the same. Anything to give a bike longer legs.
Very cool tank but why did you line the inside with wood?
You're fabrication skills are awesome, I would never have thought to use wood to layout the tank. Were do you find such large chunks in the first place?
I don't think you'll have any problems with the added weight to the frame. Those older steel frames are way stronger than the forged aluminum of todays bikes even though they are designed to hold two adults and cargo.
Good on you also for thinking out the plan for safety reason, shut off valves.
I definately see a market for what you're doing, especially for us long distance riders.
Send us the finished product so the Corporate Majority can also appreciate what you have done, shiny and pretty.
if you look close you can see that it exists of multiple chunks of wood, glued together (no nails or screws makes it easier to cut it)
went out for a test ride, works just fine. now i need to finish some details and ride it
You know somebody is going to spot that thing and put pictures online, and some BMW forum is going to spend two weeks classifying some missing-link Dakar K-bike
Good work! Now you've done it though, you are going to have to wash the bike.
VERY nice work !
It looks awesome!!
practical, looks pretty. send pics to BMW and other manufacturers, they may have a consulting job for you.
Think your going to have to update the rest of the bike with some polish and elbow grease.
Nice work , how much extra mileage did you get from that fab ?
