as you get closer to the paton the speed of the pit stop will become more important , a basic one is only a rev limiter that is operated by a button on the handlebar . this might be worth a go next year . the balance between speed and reliability is difficult to get right at the island , you always want to win but the place kills engines at the best of times ! . for me the important thing would be to keep the rider he's fast smooth and kind on the bike a very rare combination with modern riders used to riding modern bikes . good luck with the 350 !
