EMGO Gas Tank

It was reported by different sources that there is a problem with the new EMGO gas tank in that the flip up filler cap can't be fully opened. Here is a link to show some pictures of the problem area. http://cbbc.sysz.de/forum/viewtopic.php ... 3&start=15

Maybe Matt from Colorado Norton Works can confirm this? Man, that would be too bad, as this looks like a nice tank...

Yes it's a nice tank and this is the only flaw I've heared of.

The gas cap on my original steel 1973 Roadster tank only opens that far........Why is this a problem?
It opens far enough to get a gas station nozzle into it and the filler tube from my plastic 5 gal. can, that I keep at home.

I think that it's a very nice tank and something that is desparately needed to restore and keep our old Nortons on the road. If you think that this is a serious flaw then I suggest that you buy an Indian made tank and suffer from leaks and improper sizing.

I've done a couple now ( and still have a couple in stock ), and fitted a cap (original Ceeandess) to the last one - it fitted just as well as it did on my original tank- the filler neck is spot-on per original.

Those photos confirm it's as per original - I really don't see the problem?

I don't need a Roadster tank anymore because I've changed to FB-Nortons. The idea was only to shine a light on a possible flaw. :roll:
BTW I've installed two «Indian Tanks» on two different Commandos, and none of them are leaking, despite other problemes they have manifested :roll:
@B+Bogus my cap never behave as this one did... :roll:

The tanks I have sold so far, have not had any issues with the cap.

I will test a few more tomorrow and report back

I have over the years seen different style fuel caps. Some of the later 'new' offerings have allowed to cap to open to far and this is a real problem since this can cause the cap to make contact with the painted surface on the tank.

The cap in the photo looks to be a newer version than the old ones, The shape of hinged end is different than any of the ones I have. Maybe it's the cap????

Ummm, that's as far as mine opens on my original roadster tank.

same for both of mine. Personally, this would not concern me.

I think he is talking about how it hits the tank when opened that far. On both my bikes you can open the cap fully and no contact with the tank. I could be wrong, I think I was once but I could be mistaken. :wink:

I think if you look at the top photos you can see the roll pin is not through the tank, on the bottom photo where the tank is painted it looks like the pin has been pushed through the hole. My German is not very good but I think the guy must be worried about it hitting the tank????? But my guess would be it's the cap, Here is a photo of an old original Ceandess cap. The rear of it looks much more squared off.

Google translate shows that first post as saying, "Can now also understand where the problem mentioned my previous post lies with the gas cap. greeting Claudio"

Thank you Claudio, Have a great day, Chuck.

The sentence «Kann Jetzt auch nachvollziehen wo das erwähnte Problem meines Vorposters mit dem Tankdeckel liegt.» should be translated to «now I know what the problem with the gas tank filler cap the previous posters mentioned is»
The poster «Norton Motors» aka Joe Seiffert, the owner of Norton Motors and Andover Norton writes «der Tankverschluß gräbt sich beim Aufklappen in den Tank ein» what should be translated to «the gas filler cap dig into the thank when it is opened» then «Wir prüfen gerade, ob dies ohne Einschweissen eines neuen Tankstutzens behebbar ist» to «we now check if this difficulty can be overcome without realining/replacing the nozzle».

BTW. Keep in mind that my english is far away from good, but those translations make sense to me as non-native Anglo American.

There are two different guys in Germany having the same problem with the Emgo tank.

But it appears plausible to me that it could be a problem of the tank cap. I have an original tank with a new cap and the gap is very tight as well at that point when it's open .

Ralf

From the pictures it looks like the cap bottoms out on the mount, which is probably okay. I wouldn't want it to touch the surface of the tank when it bottoms out. I imagine some fettling is needed if the clearance is that tight, and the thickness of paint may also make the problem a little worse.

After checking some of the new Emgo tanks in stock, they are designed virtually identical to the original tanks in regard to the gas cap mount

No question in my mind that any issue of the cap opening to far is in fact related to the gas cap itself. As I mentioned before, I have had issues with 'new'' caps not fitting properly since when opening, they do touch the actual tank (and paint). These problems I have had on stock tanks.....so not the new Emgo tanks (Even though the results would be the same)

The image shown by 'Hortons' is of a cap that will work as intended. The lower flat on the back of the cap is what will stop the cap from 'over opening' as it makes contact with the mount

If that flat is closer to the top of the cap, then the cap will be allowed to move further back until it makes contact with the tank. This just like the image shows on the link in the original post.

So beware if buying a new cap for your tank. Fit it first (with something other than the roll pin that is easily removed) and see how far it will open. If your tank is already painted, be very careful when testing as all it takes is one flip of the cap to chip away a chuck of paint

Yes I would agree with CNW on it being a cap issue rather than the tank neck

A few years ago this flip cap was re tooled by ceandess as the original die cast tooling was basically worn out
so maybe the new UK caps are not 100 % correct or some one has fitted a poor quality Indian cap which is physically larger

Ah yes, I can see by the photo that the Emgo tank does not have the indent in the tank to allow the cap to open fully.
