OK if we reduce the load on the starter ... by say running a reduction gear will the starter spin faster ? Anyone know "

YES......BUT..... this is DC not AC....So by increasing motor-shaft speed you will loose motor-torque in the trade off and the upshot is it might not be able to deliver enough power at the faster speed to achieve what you want from it.

Torque delivery is inversely proportional to speed as shown on the above (Generic) graph but every motor design has a slightly different curve. If you increase speed you loose torque and vice versa. Keep the torque/speed parameters inside the graph and you will be OK.....go outside and it becomes unpredictable and will probably involve fireworks and unhappy faces!.
One of the characteristics of a series or a permanant field DC motor is its ability to deliver torque at low speed, this is what makes them ideal as starter motors. The disadvantage is that they require a lot of electrical power to do this hence the need for big-batteries, solenoids and heavy cables.
Its not quite what I was trying to find out ... it was my convoluted way of seeing if the savage, or the GR and GS will be able to use the same starter.
I have to find my GR starter if its not the same as GS.
