Here's the email reply - not sure I agree they will 'bed in' over time. Now I wish I had measured Zed vs OEM cables.
Hi Donald,Thank you very much for your feedback , it is appreciated.We try to find the best quality parts for these beasts when the original is no longer available. There are some very bad inferior parts out there especially on ebay, some of the carb kits are awful. We have compared them to the ones we sell and you can see why carbs do not work when fitted with these. They go for around £12 whereas ours are £58. The cables are meant to be fairly tight to start with, we had this on the originals too, so that as you start putting some miles on the bike and they "bed" in, it allows for a slight amount of give. They will soon be bedded in and not so tight.
