Just for the Aussies.
I wrote the code and it is not perfect.
It applies to Triumph twins after 1980, but will give an early date for the 270 deg timed engines as I used the code for the 360 efi model to differentiate between the early carb ones and later efi ones with the same date digit. If anyone with an efi 270 deg motor wants to let me know the 9th spot I can fix that one up.
It's an executable jar file and will be made into an Android app as soon as I have it polished.
Please note this is for Au vins as I am unsure any others will be exactly the same. In particular the 11th digit on au ones is the date not the place of build.
So could some Aussies please respond.
