How much time does an override tran help shave off?? Iam trying to get my 4mil stk cyl bike into the 6s before building a cub. This is on asphalt 1/8, currenty running 7.5s 60ft 1.63 330 ft 4.80 with a 210lbs rider on race gas.. things Iam going to add cause I need them for the cub anyways. Override 1-5,straight cut 2.68 ,lockout and 39pwks. Iam wanna try and do this without alky.
