[QUOTE="BlackLightning998, post: 4524, member: 109"] [b]Spark Plug Advice[/b] Thanks Greg - very helpful. I will have a read through FYO, ATY to see if I can find any more advice on plugs to read. Your experiences are helpful too - I may well add some of your plugs to my selection for trying. I don't think there is a "search" function on JTAN for getting access to old threads is there? PAZON are recommending Denso platinum plugs for their ignition system and the advice I am getting here in the UK from a Spark Plug specialist is: [FONT="Comic Sans MS"][B]"Denso ZU platinum options would be W20EP-ZU (projected) or W20ES-ZU (non projected), these are non resistorised plugs. You may be able to use an Iridium plug with your electronic ignition, perhaps Denso IW20 (projected). If you are persistently fouling plugs the problem is more likely to be carburation but you may be able to work around the problem with a warmer plug, IW16 or W16EP-ZU. N5C is a non projected plug and therefore will have the effect of running a little cooler than BP6ES for instance"[/B][/FONT] I'm thinking of buying and trying the Denso W20EP-ZU and the Denso W16EP-ZU and wondered if any Forum members had experience of either plug in a Vincent Twin? See my thread on the carb's to read the "latest instalment" of me trying to get my bike running properly again....... Regards Stuart [/QUOTE]
