If speed is what you're looking for into corners make sure you also get a quick shift whilst getting your slipper clutch fitted ... :|Here's a link to my R3 at Laguna this past weekend. You can hear the slipper clutch working going into the corners, allowing me to maximize corner entry speed. On one corner, I downshifted too early and the SC saved ma' bacon. Just rev's higher.
Like Ruby has installed, this is a Yoyodyne but with stiffer springs to keep (to me) the stock engine braking alive. Without those springs, the engine braking was too weak for my tastes.
Let us know how you like yours. I haven't any experience with that one.
Sorry for the tilted angle!
