Thanks for the info guys. Where can i get a puller from? The olny mods I have now are FMF Fatty's with Powercore 2 Silencers and a K&N filter in the airbox with the lid pulled off and a outterware on it. I'm on this site everyday and amazed of all the badass bikes out there. Im also thinking about doing a coolhead too. But im all new at this. I just need some guidance.
