[key4202003]

hey im looking for a 13t sprocket for my 03 400ex. rocky mountain has one for an 04-05 400ex, but the part numbers are different, will they interchange?

if not who makes one? thanks josh

moose has one for older EX's, check with C&D or your local dealer to get one.

you will be shifting very fast in the straights with that sporcket i suggested just a 14 or a 39t R ,15T F. there is a such thing as to much tourqe when you whellie up on the bar every time you give it gas:cool:

yea thats true, but what if your making a sand hill shooter? i have 20-10-10 10 paddle tires, HMF head pipe, white bros slip on, uni air filter, no lid, and i dont think ill be able to pull those tires...

I use a 13t with a stock rear, it seems to give me the right amount of torque when i'm trying to get out of corners during a race.

wouldn't a 13 t make 1st gear useless? As it is you can only go 10 to 15ft before you have to shift.
