Hi had my tank resprayed is there a dimensioned position of the norton decals or do people do it by eye?
By eye, level to the ground with bike off the centre stand, look at pics in the Norton brochures, it's well forward on the tank.
Believed to be from a standard bike.
... but I think they would look better a bit further back and maybe slightly lower. Having said that I spent ages shuffling mine about on the ES2 till I was happy. Still better than choosing the right Arden Green for my Fanny-B however.
I have to agree with Ian, I put mine further back and got them made up smaller which In my opinion looks better.
They need to be far enough forward to be in front of your knees, don't they? Otherwise people might think you are riding a H****?
I think I remember reading they were applied on top of any tank lacquer. Then they can be replaced if they fade - or if you aren't satisfied with how they look.
The attached pictures show my tank before it was stripped for re-painting. Bike is a 1977 850 MkIII which I have had from new.
Hope it helps. Let me know if any dimensions are unclear.
I think your positioning look about as perfect as you can get.
