Hey guys, I've found this seller on eBay Australia selling a factory HRC cylinder for 2005-2007 models. He says the cylinder is professionally ported at the factory before being shipped out to the honda race teams back in the day........he also has listed a few other factory parts like HRC expansion chambers etc....... I'm a sceptic......but I want to believe its real.......could there be any truth in this? I hope so because I just won it for $270 AUD! If it's not real then I end up with a spare cylinder to play with, so it's not a big lose, IMO. Photos to follow when it arrives, any wisdom out there? Any suggestions?
