I've read some of the posts about converting the stock tube to the Yamaha 1/5 tube. I ordered a 05 R6 tube and installed it, but am having serious problems with the throttle sticking open. If I adjust the cables to allow the throttle to close (it does so very slowly and doesn't close all the way), they have too much slack. If I adjust to take the slack out, the throttle sticks. Could someone that's done this aleady please tell me how to fix this problem?
