Andi, never measured the fuel consumption...just fill it ride it,fill it ride it sorry
your hooked base plate can be dremelled bigger and the bottom of the stacks sliced off to fit thats what Griff did to
taller stacks from tuono = more midrange
shorter rsv stacks = more topend
I lost 1 bhp using the longer tuono stacks over the shorter stacks at peak rpm but all across the rev range is a healthy improvment except @ 7500- 7700 where there is no difference.
anyone wanting to see the chart could let me know how to post it up on here 'cause I dont have a clue
