Well, I don't think my maths are up to much. I had 3 to 1 on the first chain from the engine and 4.1 to 1 on the second. I added them up and came up with 7.1 to 1. I actually had about 12 to 1. So I have made a couple of sets of change sprockets to alter the ratios. Currently 8 to 1. I also changed my steering slightly by adding another track rod. This made the wheel angles better at full lock. I felt I would get a lot of under steer using the kart type of set up.
