XR 400 Sprocket selection

[Kawidude]

I just found out through another post that the stock sprockets on an XR400 are 15/45 and I'm totally happy with the combo. My brother-in-law also has an XR 400 and he'd like to get a little more pop out of the bottom end by switching out a sprocket. Is anyone running a sprocket combo other than stock that they're really happy with? Thanks in advance for any info.

I liked 14/45 and that will fit with the stock chain. 15/48 is the same thing but you need a longer chain. 13/45 was too much low end for actual riding but it was fun for doing wheelies.
