Haynes Spark Plug Chart[/list]

According to the chart that Kerry posted, looks like its just time for new plugs. 

well they are brown in color they are brand new just put them in a few weeks ago i should post a pic

your ruing fine, check the gap and reinstall. light brown/tan is the right mixture

here is the pic kinda hard to see but maybe you can tell

Plugs are cheap...if you think they're not cool, replace them.

Those are looking kinda ugly,man. Have you done something different like changed your mixture or added something to the gas?

Looks like MTBE.  I wish my left plug was that color....

Explain....

MTBE in gas causes that dark reddish color.  It's perfectly normal. 

I wish my left plug was that color because I recently got my left cylinder running right, and it's still black because I haven't replaced them yet.

i have been running berrrymans b12 in the gas to help with the cleaning of the carbs

yea dude there fine, clean them with carb cleaner and regap and install and go. i wouldn't change any thing ont he carb (mixture ect...)

Color looks fine.  Can't tell from the fuzzy photo, but it looks like it's going to be time to replace them soon.
