'87 WR400/430 Tank Difference?

[AdamN]

Back for more education lol.

So I have found a hole in the tank of this WR400 from a butchered pipe mount that goes around the frame under the tank. Had a bolt that was too long and has worn a hole. Now it 'may' be fixable with a little plastic welding but not sure if I want to go down that path?

I have seen that the part numbers for the two tanks are different and the WR430 is a 12l capacity while the WR400 is 10l. I have also bought some radiator shrouds off a 430 on Ebay before I learned that they too have different part numbers to the 400 ones.

Will the WR430 tank fit on a 400? The seat and both radiators have the same part # for both so assume they interchangeable. So if I get a 430 tank I can use the 430 shrouds and it should bolt up to the existing radiators?

Where does the 430 tank hold the extra capacity? Does it have a taller profile to fit the extra 2l?

Thanks for your guidance.

it's wider in the front
so your question will it fit, yes
so you need a tank, which one? 10 or 12, look on the bottom of yours and you will find the part number
look in the fiche to see which it is

guess I should have digested what I read
the tanks are interchangeable as long as you have the right shrouds, I run both at different times on my 87 430

Thanks 2premo thats exactly what I needed to know.

I will get a 430 tank and use the 430 shrouds I bought.

Thanks

FYI the 10L shrouds also fit the CR models, same tank
yours pretty clean??

 

[justintendo]

the 400 and 430 have different tanks?? i thought it was just a difference between cr and xc/wr...

 

[2premo]

the 400WR uses the smaller tank
if you look at the list it seems odd, but probably marketing to the correct user in that market
a motocross and enduro would need less fuel than a cross country model

 

[2premo]

do you need a 12L tank? I have a couple laying around, make you great offer, as in cheap
PM me if interested

I thought the 400WR became the 430WR in 1987. At least that is what I read in the Cycle World test of the 1987 430WR.

from what I saw they just phased out the 400

We still got the WR400's until '88 here in Australia, not sure why?

dumping ground...like the MR 175's and 250's

And my two '88 bikes both have different tanks/shrouds, not interchangeable without looking stupid.

250WR and 400WR Greg.

The shrouds will actually fit, but not properly, bulging out on one.

I thought the wr was bigger than the cr and didn't matter if it's 250,400, maybe even the 500. Just two tank & shroud combinations. I could be wrong...I also had to use a hot air gun to create a "dent" on the underside to make room for top exhaust mount bolt.

a dent???
if it doesn't fit, somethings wrong, like wrong bolt, too long
looking in the catalog it shows a mish mash of the tank selection

that means it doesn't fit right, just trying to help

 

[oldbikedude]

if it doesn't fit, somethings wrong

or it has an aftermarket exhaust adjusted to tuck in tight
