Thanks mate, thats where I was going wrong was using a brand new plug and it just refused to colour up
Oh well the current plug has been run for 50 k's with a 180 main so it should be nice and black and make step downs easier to read. (And yes I know I was a moron for running a 180 main but after stuffing round for half an hour I just couldn't be bothered and rode it that way as punishment
I might try jetting the blue needle correctly and then later jet using a Suzi needle. I'm wondering if the blue needle is also partly to blame for my 'boring' top end?
