sprocket combo?

[atvlvr2010]

I have an '05 450r and I am running a 15 tooth front sprocket and a 36 tooth rear sprocket. I am going to be running mx this year and was wondering what sprocket combo some of you think works best for mx. I am running 18x10x8 rear tires also. Any input would be appreciated, thanks

most people that i know run around 14 x38 or 37

14/38 with 18's was always pefect for me. 3rd in almost every corner and 4th in most straights

First gear in the 04/05 is geared high from the factory. It's geared too high with the 14 sprocket. I couldn't imagine riding with 15-36. It seems as though you would have no bottom end power, even with 18" tires.

This is the combo needed, for the big CC engines, with a big cam.
It will pull all gears. :D
