MessageI spent some time about 13 years ago getting a fair amount of =
input from the list on the rotor thickness. If I recall correctly most =

information stating that .375 was the minimum (below). =20

.375 seems an awfully large amount out of a stated .500 rotor. If it =
matters I had my rotors turned and of the four I had done they were in =
the .435-.460 range. I had a hard time finding someone to turn the =
rotors being they had no actual number in their database (or on the =
rotor) to work from. I eventually found a Triumph guy at Pep Boys who =
was willing to turn them as long as I stated on the invoice that the =
.375 was provided by me. Initially I was only going to get one set =
turned, but when I finally found someone to turn them I dashed home and =
got the other set too - not wanting to miss the opportunity.

Every part has allowable manufacturing tolerance specified on the print.

I believe the brake discs should be about 1/2" thick but I don't know =

The disc thickness will be weak, the size if disc is odd. Should be =
same diameter on series 3-v alpine and tiger.

Hello All:
The other day, a friend who owns a Tiger II found that one of his pie =
mags would not=20

hub off a Series V
Alpine that we have been dismantling and found that the mag would fit =

very easily. I would have thought that the hubs used on the Tiger II's =
and the Series V
Alpines were the same and, as far as I can find, there is only one =
part number on the
Parts List, but they are slightly different. Can anyone offer any =
insight into this situation?
We also noticed that the brake discs on the Tiger II and the Alpine V =
were different, with
the Tiger disc being thicker but slightly smaller in diameter than =
those on the Alpine.
Are these just ordinary variations in manufactured parts of is there =
some other
explanation?
Thanks,
