I have an '02zuk1k. I am presently -1front with 169rwhp. But I presently weigh in at 230lbs. I am being pulled on by 2 guys weighing 141 and 120lbs. They both have zuk1k's with 150-155rwhp with stock gearing. When we hit in second I jump out about a bike length but when we switch to third they pull on me and keep pulling every gear thereafter. Someone told me that even though it does not sound right but if I go -1 front and +2 rear I should not lose top end and still have that pull at low and mid range. Is this true? If not do you have anymore suggestions on what I can do to even out the acceleration of the bikes with the gearing? I am not adding Nos to my bike either. I am trying to accomplish having at least the same pull or acceleration as the 2light guys and let our skill of riding be the deciding factor. We run a 21 mile course that we stay on top end with a few nice long curves that one can take at top end as well.
