on my stock motor i like the stock gearing for the tracks i race, but now i put a 440 kit in it and a cam with a 39 mm fcr carb, what size sprockets should i use to get around the same lowend and a little more top end???

Well, if your wanting a little more top without affecting low too much you could go down on your rear sprocket a tooth or two. Changing out the front is a lot more convenient but one tooth on the front is equivalent to 3 or 4 on the rear I think. Hope this helps. Good luck.

well a 440 is goiing to have a ton of bottom end, and the 400ex already has a lot, so id go down to a 36. Ur still going to have more than the stock 400. And your going to gain top end.

I think that is what he's saying. That setup would improve top end while retaining the case saver.

When I had my 440 the people who built it for me told me to run a 16/36.
