Well, they're a couple months old but still shiny on the outside. Where should I kick it?
FYI - Many people here (those running popular ad-blocking software) can't see the picture I think you posted. When a picture is the last thing in a post, ad-blocking software tends to think it's an ad and removes it.
Inserting text, even just 1 character like a ".", on a new line after the pic keeps it from being blocked.
Or, you can setup a signature line in your user profile.
OK, but without a decent pic or 2 of your plugs, looking down into the plug, people can only make wild guesses as to whether or not you have a problem.
More open pipes and/or air cleaner? They come lean from the factory and if you do much to open up the intake or exhaust, it gets worse. A carb adjustment and rejet is probably in order if you've modified it.
