Still trying to figure out whether or not to rebuild my 2007 XB9 5600 mile basket case. All 4 cams suffered damage from the spent rear rod bearing. I don't want to dump a ton of money into a big bore high HP rebuild now, I just want to get back out and ride so if I can get my hands on 4 good stock cams I'll do that. Are they a common cam with XB12 and sportsters?
