hi there,

i have just ordered a speed passion 6.5 turn motor and i need to know a good starting gear ratio. i currently have a 83 t spur and i have looked at setup sheets and alot have them geared at about 21 to 23 tooth pinions?

i have a 23t pinion would that be fine for a grass track that varies from large to a small track?

many thanks

lewis
