i am thinking about going from 3.73 to 4.56 . can anbody tell me how much top end i would lose and how much would it help me in the 1/4 mile ? thanks! p.s. i am running 16.66 in 1/4 mi.

 

Got the gears just about broke in. I have noticed a small decrease in mileage and a small increase in power. Nothing major but you can feel it. I am pretty sure that I will like the setup though regardless of the mileage.
Going riding tomorrow so I will have the trailer hooked up. I will let you guys know if there is much difference.

 

You have to fix your speedometer now with a tune.

 

You won't loose any top end ! Also if i were you i would choose 4.88 because of your huge tires.
