Steel Interstate Tank

Deets55 said:

Working off of memory I thought I read somewhere on this forum that there were a couple of different size Interstate tanks made available throughout the years. They varied in width and length. This is one of the reasons that Corbin stopped making seats for the Interstate. I also think that CNW had a service where they would modify a Corbin seat to fit your tank. You would send Matt the tank and they would modify the seat accordingly. I'm sure Les has better info, hopefully he will chime in.

The Interstate tanks vary slightly in shape and certainly in capacity........


.....maybe there could have also been some variation in the fitted position but that's just speculation.

One is the diamond the other is glass

72 combat glass, steel tank year Unknown , well the guy ( from Glasgow) told me at the time and I forget.

If you take a look at my photos in this thread of the tank compared to my original. It is smaller in width but the same in length. The corners on the tank near the seat are more beveled, narrower and rounded compared to my original glass tank. The photos I have seen of the original steel tanks looks almost identical to the India tank I got. I don't know if the tooling changed from year to year at the factory for the steel ones but they are slightly different from original glass tanks.

Along with the fibreglass tanks, as with a great many other Norton parts, the steel tanks were most likely sourced from an outside supplier, possibly more than one. The later ones being of Italian origin, allegedly.

I think you must be right les, cos when I flipped up the "gas" cap it said " eat at luigi's" .


oOnorton your bike set up looks good, what year is it and how did it start its life before you made it your own? It's not often you hear someone admit their balls ups , but we all have the " shelf of shame " in the workshop.

Ha ha... As a transplanted italian from NYC, the "eat at luigi's" made me laugh....

My commando is a '70, but it had a disc brake front wheel and late model switch clusters when I got it. I bought the bike in '77 from a friend who couldn't keep it running. It had the same bars you see, standard norton spoke wheels and POINTS!. Here she is on my lawn sometime in the '80's. I really liked the look of the chrome shrouds on the original shocks, but the Koni's are better shocks, so I made the change.



I wrote a long story, but the picture probably tells you what you want to know...
