i purchased a 2001 929rr when im inbetween 1000 and 3000rpm my bike shutters horribly i have a micron exaust i did find a vacume line that had a 't' on it and two lines off that which weren't connected to anything by my rear shock does any one know what they go to the main line goes to my fuel tank

I think it goes to your fuel pressure regulator, which is on the left side of your bike as your sitting on it under the gas tank right between the frame but I could be wrong but that's where I saw the T connections of hoses!!
