Gearing Help?

[bubbag]

Hello,
I have a 88 R but I have noticed that my gearing seems to be running out too quick and I think it needs to be geared higher?
I have the following engine mods:

FMF fatty exhaust
ESR 38mm Keihin airstryker
ESR airbox eliminator
ESR CR Ignition
Wiseco Piston
Boyeson reeds
CR Head gasket
100 octane low lead.
and 20 inch rear razr tires

I'm curious as to what I should change for the gearing it seems to have the motor too pull more but not sure as to how many teeth I should be running, right now the gearing is stock....

Thanks
Bubba

well what is your gearing now an what type of riding do you do

[bubbag]

gravel pits, hill climbs, occasional mx, and lots of trails and wide open fire roads....
