- April 15, 2013, 20:01:19 PMI know hooserfish is more about if it can be done, and I am wondering if it is worth it, so I just did a run to my sister's on Microsoft streets and maps, either tank and the info on fuel consumption for my last trip there, it is 448.5 kms or 278.7 miles, now i did the fuel use and such according to my last run down there last summer, and I needed to refuel twice, if I were to add the larger tank I would still have to fuel twice on the trip. Right now the only advantage for me would be if I were out riding the YellowHead Highway..... for $1200.00 that is like 888 gas stops.....

- April 15, 2013, 19:56:03 PMJust been poking around, and found out the tank on a 1500 carbed classic is 4.2 gal...doesn't sound like it's worth the trouble.

- April 15, 2013, 19:39:05 PMDon't forget to consider what adding that size tank does to the center of gravity and weight of the bike. Still plenty of power, but it will feel heavier I'm sure.
But this is one of those mods that someone really oughtta try... and take pictures of... and write about.

- April 15, 2013, 19:36:40 PMYep, a gallon difference (800 drifter vs 1500 drifter - Troll says a classic is 4.2 gallons)
The best way to check the positions and connections is with a side-by-side comparison and mock up. Maybe find an inexpensive tank and have a look... use it if it works, resell it if it doesn't!

- April 15, 2013, 19:33:22 PMCDNRATMAN, The 800 tank conversion expanse it to 6 gal. for the $1200 , more cost for the 1500 carb. tank & even more cost for the EFI tank.

- April 15, 2013, 19:21:05 PMhoosierfish, did you ever find out what the expansion in tank size would have been for $1200.00 by chance? Good question of the size of a 1500 vice a 800 tank too....the 800 is a 4 gal or 15 liter fuel tank the 1500 from my reading is a 5 gal or 19 liter tank. So a gallon difference, then the cost too....

- April 15, 2013, 19:19:42 PMTroll, After all this stress on my brain trying to get more capacity in my fuel tank & thinking I might switch out my 800 tank to a 1500 tank I got to thinking, just how much bigger is the 1500 tank compared to the 800?
is it worth the time & effort to do this?? I'm thinking maybe 1 gal. diff.

- April 15, 2013, 18:49:36 PMYeah, well...fabrication is us...I have 2 diagrams for the 800 and the 1500a tank. They both use the rubber spool mounts in the front, but the spacing might be quite different. Without having the side by side, it's pretty hard to tell what will fit, and what can be made to fit. They are not like 4 speed Harleys that can get almost anything to bolt on. If you could find a wrecked tank from a 1500a...cheap....just to see if it can be made to fit.

- April 15, 2013, 18:32:58 PMThe frames are different on the 800 and 1500 (drifter and classic)... that will likely make a big difference on tanks. I have never heard of a successful transplant... but that doesn't mean it can't be done.

- April 15, 2013, 18:02:43 PM Troll, Your's is the response I've wanted to hear, not small talk on bladder size 
. Troll are you familiar with the mounting points on the 1500 & 800 tanks? I was thinking of doing the same thing you stated: using the 1500 carb. tank, hoping to here from someone out the in Drifter land that has already did this. By the way I did get a hold of that Company that will expand your gas tank to a larger capacity but hang on to you wallet,... it's a whopping $1200 just to get started..!!! So I think I will try the tank swap idea. Thanks
