my bike is a 07 yzf450. 48 pilot, 168 main, stock needle 4th clip
Do I need to do the O ring mod? Can I do this without removing the carb? I had a friend work on my carb a while back, I think he used safety wire before on my bike but im not sure. He also said something about a grinder also. Im hoping maybe the safety wire or the o-ring broke or came undone.
