how much slack do you remember there being in the cam chain on the xr when you did it??? we seem to have tons of slack in ours. enough that the tensioner doesnt do anything. was it pretty tight when you put the cam sprocket on??? our sprocket looks great, like no wear, but we cant get the cam dialed in even close and can even skip teeth if we try. so we think the chain is toast. if its supposed to be tight, we'll get another one. if its loose, maybe we'll look at the tensioner a little closer. since we didnt have ne to take apart, were not sure what its supposed to look like. this motor was a basket case.
