stock sprocket and jetting sizes

[flees41]

I bought my son an 06 TRX90, wondering what the stock sprockets and jetting is for this quad. Also does anyone know if (stock for stock) if the older 90's or the newer 90's are faster??
I thought I read something on this site awhile back about the older ones being faster...

Thx

According to RMatv the gearing is 13/50.

No difference in the old or new ones the stock 90 is pretty slow
