i would like a 12 tooth front and a ** rear sproket. what can i go to and still be able to ride at 65. can anyone post a link to where to buy these? all i can find are 250s sprokets and they have a different part number on the crank so i didnt think thety would fit? any help would be great. thanks in advance PS my mods are q4 air box lid delete 128 jet. thanks guys

 

and any other free mods?

 

a 13t on the front with the stock 39 in the rear is a good ratio. a honda xr650L front will fit are bikes. how do i know? I have one on my sf. the s models are compatible with the sf.
