i just installed a se comp kit i got from thr dealer to replace a old new style se comp i got from the dealer in late 2008. i changed out the whole thing including the new rotor then. im replacing it wth this kit 42200064a. After installing it the primary cover wont go on. The chain looks to be off a litlle bit 1/4 inch or so as well. I was reading that i needed another rotor or should have gotten a different kit that included the rotor. pn 40100061. Any other way to make this right?
