does anyone know if the 11 tooth sprocket from the lt230E fit on my lt230S which come with an 12 tooth sprocket. Also, will this help out my performance enough to notice?

 

They should be the same. The 230e came with 11/41 & the 230s with 12/41..I have tried the 11/41 combo and it gave a bit more grunt on the low end (not much) and made 4th & 5th gear approx. the same. No top end what-so-ever. But, if you've got one to experiment with..give it a shot & see how you like it.

 

i run 12 39 and it is the perfect combo for me but with the big bore kit i think i will go back up to 13 39.
