Uu Mr.E uU

i presume thats the reason for the two diferent lengths, so u get an average gain all round. well thats my understanding. were as if you have the two 35mm ones, the gains are more focused at the top end as factory pro claim on thir website.

these measurments were originally designed for the poiunty and have no idea how it will affect the curvy as carbs are strange and complex things to get right to give you the desired performance. however, by all means have a go. the worsed thing that can happen is that you might need a bigger jet to cope with the faaster moving air due to the function of the stacks.^_^
