Skunk tank fitting on later GS 1000

[John Kat]

Having purchased a NOS skunk tank a while ago, I decided to fit it on my GS 1000 XP that has CV carbs fitted
Guess what, the OEM fuel valve ( worth a pure fortune in itself!) interferes with the carb bodies
Not to worry, I decided to buy a Pingel fuel valve as it looked far more compact than the OEM model.
I got the valve and a 46 mm adapter plate and tried fitting them today.
Well it still doesn't fit without interfering with the carb body.
In fact the adapter plate has a hole spacing of 46 mm and in reality you need a spacing of 44 mm!
I had made a quick measurement before ordering but...I thought that Z1 knew better and maybe my measurement was off by 2 mm
In practice I'm going to have a new adapter plate made with a 44 mm hole spacing and on top ensure the fuel valve is offset by at least 4 mm backwards with respect to the adapter plate.
I'm surprised no one else has encountered this issue?

You can buy offset adapter plates. I use one.

I guess the dreaded 80 petcock was made for this reason.

At least partly.
In fact on the later tanks the hole for the fuel valve is set further back

Good news!
Where did you get yours from?

How much clearance does it get you?
I have only a 1979 tank for my 1980 1000E.
It has the same problem.

I used one on my 80 and it cleared. Just point the actuator away from the carbs.

I got my offset adapter plate today from Z1 enterprises and in no time I had the Pingel fuel tap on the tank and the tank on the bike.
Here's what a NOS Skunk tank looks like on a later GS 1000
The space is tight but...it works!




Many thanks to Z1 enterprises for accepting to take the previous adaper plate back!
