I am presently 1 down on the front. I weigh 230 now but my fellow riders weigh 141 and 121. I have 169rwhp and they have nothing but full systems. We hit in second and I jump out about a bike length and they pull on me when I change to third. They are stock gearing. I have been told to go up 2 in the rear and I wont lose top end. I just can't see how that is true. I am thinking of going back stock front and adding 2 to the rear with both sprockets being afam. Is this a better move than my current setup? Will I gain a little more top end with this change? I Know I need to lose more weight but its not happening over night. I was 248lbs in January. So I am slowly getting it down. I know I will never even try to get to their weight. Ijust want to get to about 218lbs. Anyway should I go back stock front and add 2 to the rear? If not what is your best recommendations and please explain why. Thanks to all in advance.
