What do you think about Boyesen 2 stage reeds, I check the search and i saw that it is good but I heard that the second reed is too fat and never open in 250 2 cylinder bikes and it is only for one cylinder dirt bikes!
If the second doesnt open the nsr will have good midrange because the small reed is thin and opens fast but at 10.000 rpm the nsr loose power and the stock are better!
What do you think?
