[QUOTE="greg brillus, post: 144163, member: 597"] The colder the plug the harder it is to clear itself of deposits........ These engines tend to run and should be run on the rich side, so they do tend to foul plugs. Even the Champions will foul up if the mixture is too rich........Once a plug fouls up, it can fail altogether, even if removed and thoroughly cleaned. Best to simply replace them and start over. It is very easy to flood these engines on start up.........ideally you should use the tickler or the choke but not both.........Engines with big cams can be hard to start due to the excess overlap........this is the case with my bike.......once running it performs better than most other Vincent's on the road, so I have to live with the starting issue.......It was difficult to start until I realized I was flooding it too much. I run Champion N5C in all these bikes now. [/QUOTE]
