There were a few bikes that ran out of fuel a Harrow this year and l was very close to empty myself at the second fuel stop. I had read somewhere in internet land that someone had fitted an '83-'85 kdx250 tank to a '83-'85 200 so l thought if the 250 carries a bit more fuel it'll be worth the effort.
I didn't measure the actual capacities of the tanks but only the differences.
The 250 tank holds around 2 1/4 litres more than the larger later model '85 200 tank. The '86-'88 200 tank holds around 2 1/2 litres more than the '85 200 tank but wont fit onto the '83-85 frame.
The front mount on the 250 tank lines up well on the 200 frame and l used 2 rubber insulators on the frame. As the 250 tank is longer the 200 rear mount went and l used a broken exhaust rubber mount to support the rear of the tank. A washer under the mount got the height right so the tank has 4 points of contact/support with the frame

The 250 tank sits around 20 mm further back than the 200 tank at the rear so l took 20 mm of the front of the seat trimming off and shaping the foam with the angle grinder. l kept the seat sitting firmly against the tank for extra support to the tank as I've just used a cable tie on the rear mount until l can work out something better.
Clearance around the exhaust for the 250 tank is simular to the 200 tank.

Looks like a bought one :)

If l could sew l would have trimmed the front of the seat cover to match the shortened seat but the excess gathered well enough under the seat.

So how many actual liters did you have before and what have you got now? Sorry i do not know KDX capacities so "2 &1/4 and 2&1/2" more does not mean much to me. I think Clarke make tanks for these bikes too.

Kawasaki quote 12.5 litres but l just needed to know how much more fuel was in the 250 tank l had than the 200 tank l was using.

Great solution Geoff, and you're right it does look like a bought one.

OK so you have gone from 12.5 to 14.25-14.50L. That is a good size, would need to be a big loop to run out with that much.
-
Good solution, well done.

Kawasaki quote 12.5 litres for the 250 tank.
If you've got a kdx200 and you want to pick up a couple of extra litres of fuel, the 250 tank is a straight forward fit.

You're an ideas man, Geoff-er-ey!

Fuel bladder in your backpack......
and you can use it on all your bikes!

Or, you could use try one of these:

Still not as good as the original idea if you have a KDX though.

Funnily enough I was considering fitting a 200 tank to my 250 a while back in order to try and give it the feel of a smaller bike :o

Carrying fuel on your body isn't the wisest of things to do.

But its sometimes unavoidable on longer rides aluminium hiking fuel canisters work well for an extra couple of litres but if you can afford a bigger tank or find one that fits all the better good work Geoff

;D ;D ;D Oddly I agree with you Mr Morris,,, ;D ;D
I have done a lot of crazy things, my mind boggles that I am still alive,,,so far ;D
But I wouldn't do that,,ah well unless,,,,, how much does it pay ;D
KDX has raised a good piont, and done a good look solution.
What other options are there, Top of the rear guard, front of the triples with the head light out further.
Bigger tank is the go if it comes together like this one has.

I know we often do things we shouldn't (me included) but Aluminium canisters would be worse to be carrying on your body, it would be a solid item to fall on.
Strapped to your bike would be okay
;D ;D ;D Oddly I agree with you Mr Morris,,, ;D ;D
What has this forum come to ;D
-
KLX did a full lap on one tank! Didnt even hit reserve :P
-
I would have bet that a KDX 200 would get 100km or more from a tank ( owned an 87 ) Good solution thou.
-
But did u make it around on one sump
Full of oil ::) ;)

On longer trips (4-5 days) into the high country they are carried in the side pockets of my large camel back pack you don't even feel them and they are usually emptied asap , the spare tubes , tools , pump , clothes , food and rocks that you would land on would be just as painful if not more so , tried the bum tank on the rear guard works okish but restricts movement on the bike to much , bigger tank still doesn't cope with the longer distances on some trips so it is a necessary evil and there arent to many approved containers that will do the job.
