So do you have any experience with Norton's or any older British bikes for that matter, if you are new to Norton's then you need to learn how to kick them if it's a pre 75 and expect to work on them, but it's the only way to get to know your bike, but as I have said in a direct message too you I am only too willing to help you out, I am no mechanic but I do know my Norton and everything about building and working on Norton's and have rebuilt a few over the 48+ years of owning mine as well I have a full workshop and every tools and everything to work on Norton's, I am always willing to help with anything at all, I will send you my phone number if you like to have a chat.
