Gearing

[marchuk]

going from a 146 to a 163 wondering if i have to change any gearing?

Yes. Your bottom gear should be 45 tooth right now. You want a 49 tooth at least would be my recommendation

I run a 21 top changed 2 a 51 bottom

20/51 gearing also I would do some clutch work too

From what I have heard 2.5 ratio is what your after and yes I agree some clutching would be in order to maximize your power

I got a full dj clutch kit with ramps, and either 20/51 or 21/51 to pull that track, you would need a 106 chain, let me know if interested.

Need more info....what engine, sled etc...? I see a 872 in your signature. More power can pull taller gearing.

I run 21/49 and it works for me
