I find if i'm ever doing a job like this, that i'm not overly familiar with, i take photos as i go along so i can see where everything went. When i fitted my restrictor kit and put everything back together, my bike didn't start initially. I couldn't understand why. Then i remembered that the fuel tap was still in the off position Double check that this isn't the case - it's easily done! It would have run initially from any fuel left in the carbs, but then would stop and fail to start if there was no more fuel getting to it. If you are using a manual, you could always take everything off again and follow it in reverse steps to see if you missed an important cable or hose. Good luck at any rate
