run my Orion V2 (black alloy endbell) on 23 to 25 with 81 spur depending on size of track

22/81

I normally run a 23/81 but it all depends on the track really!

I see no-one's gone for my personal favourate - 20 tooth pinion on std spur. Awesome punch, not too bad top end. Needs to be a revvy motor though.

Ran 22/81 with my 12x1. Seemed about right, wasnt the fastest but certainly not the slowest.
