View Full Version : bsa b25/triumph tr25w cam timing question

12-17-2010, 1:49 PM
Hey cats, got a triumph tr25w 250 single Im rebuilding into a dirtbike.
Does anyone know the deal with the two marks on the camwheel?
I've read that if your camwheel has both the v and the dash, youre supposed to use the "v".
Can anyone verify this?

I know the later motors lined up the "v" with the crank pinion mark , but the motor I've got is such a mix and match I really dont know what it is.Any help is greatly appreciated. thanks.
