Thanks guys, fortunately I got the tam pipe in the sale so that's taken care of.
I have been reviewing the redesign thread, looks like a good resource, I also got a message from the gent who sold me the jet and he directed me to the appropriate thread
Andy, Thanks for your concern, I guess its hard for folks to not take a dig a fej which is understandable i suppose but fyi I have an old version NIB sans honeycombe with a tam pipe and am perfectly capable of carrying out any mods I deem required.
thanks guys
Kim
