Hi,

If it helps, here is a link to the death rattle of the original "harley type" compensator on my M3W. I went through two of these before they finally put in the Centa Drive compensator. Your squeak sounds like something else...... Definitely have a quick look under the timing belt cover and check for a loose spark plug????
