He is correct ^^^^^^^^^^^^^^^^^^, don't take this the wrong way but many new people come here with a problem that they think they have diagnosed correctly and put out a simple statement as above only to find out later that it was incorrect. Many days and dollars later they come back and start asking other questions because buying all those parts didn't fix the problem.
So give some info on the bike like, mods done, year, how you diagnosed the problem, there is always a chance that it's something else.
