i just put my 13 on and went out and rode it.i could pull wheelies in 3rd with the 12 but now i cant.i did notice a bottom end loss but i gained quite a bit on top end.it did lengthen every gear so i dont think ill be so reved out in the lower gears now when im in the trails.im goin riding this weekend with some buddys.ill let you know how it works out and if i think the 12 is better or not.

 

I find myself unable to decide if I like the 12 or 13 tooth front sprocket better because with the 12 tooth it seems like I am constintly shifting thrue the gears but am able to ride wheelies very easy, but with the 13 tooth it is streched out nice so that I dont have to shift so fast but I find that it is much harder to ride wheelies. I have the 13 tooth sprocket on right now but I think I am going to switch back because I like to have that lowend power.

 

i think thats gonna be my problem.the 13 tooth has great top end and ok bottom end.the 12 tooth has great bottom end and ok top end.im kind of stuck.we ride trails and open fields.i would like the 12 for trails and wheelies and the 13 for fields and roads and MX.

 

instead of going back to 12 up front try adding 2-3 tooth more on the rear.
