Just curious as to what the stock tooth count and pitch is on the sr10m. Seems I need to have a few extra pinions and want to know what I need before buying the wrong pitch.
 
I was wrong

Yeah, I looked at the manual PDF and all it says is the pinion and set screw are not supplied in the kit. I know I have to go up a tooth or two so may have to remove the cover and check after work thanks for the help anyway.

Look at the manual and see what the pitch and tooth count of the spur gear is. Then just order a handful of pinions around about the tooth count of your current pinion.
 
From what I can see it seems the pinion is a 18 to 21 tooth. I was going to get from 16tooth to 23tooth pinions so I can have adjustment before I buy some larger and smaller spur gears. Just doing little bits at a time.
