well just rode my 480 powervalve cheeta w 38mm lectrons on it and alky i noticed that the plugs are brown in color. looks like chocolate brown maybe burnt oil? not clean the bike runs hard and has MONSTER bottom end and throttle response it never runs on or sounds lean at all. after the run it drops right down to a nice low rpm . i was running br9es plugs i forgot to switch them out to the evix's i usually run after tuning it a little..

just weird to me that they are brown there was a lot of oil in there from purge a few times... and i had some overrev/ clutch issue's i will look at the o'clock rings tonite...


is this a possible problem or is it ok? just got this motor back together and seeming to runn good and i just dont want to blow it up.. the motor "sounds" fine... ????

My alky. Plugs usually run a little lite to darker tan BR9EIX. Not dark tan. But engine might like it with a little more fuel.

Cam thats how the 350's plugs look, cardboard color.

my plugs look like cardboard to.

sand moutian nevada plug, i have light brown safe and perfect for a long azz hill
they are from a used box for notes and have sand one them,lol

that dark color must be a shadow,it all looks light brown, perfect

Man thats a big honkin ground strap. lol

oh WHEW i was just a little conserened... my big bikes plugs usually look just like a new plug nto really anything ont hem but that one has an egt on it so i cna set it rich to slow it down and then iff i need to squeze it a little leaner to get a few more out. and not hurt anything....


this one was just a first with no egt adn as far as i was concerened the motor wasn't showing any signs of being lean..

not sure what the dif is,

dont know if these help but thes are mine after a weekend of drag racing. I dont do by the color I go by the heat it making
