gearing 190 lb rider

[n20joplinbusa]

I am going to be stretching my bike out for the drag strip 4 inches(I weigh in at 190). Was wondering if 16/42 would be good for this? And also was wondering about how many links i would need for the chain. And if im gonna need to do anything for the brakes. I would also like to know if my n2o bottle would fit in the stock swingarm with extensions at that length. Any input is much appreciated

16/42-great
chain length-124 link min.[buy a 130 link and cut to fit]
brakes-loose the right caliper and run a steel braided line to the left.stops great and loose weight.
n2o bottle-I don't know
