just tryin to stirr the Shiat

Champion spark plugs SUCK !!! Straight up SUCK !!! Every time i've used Champion for the past 40 fook'n years they SUCK !!!

Maybe ok for a Dragster , one or two runs down the straight , then pull em to put a new set in.

Maybe ok for a lawnmower that never sees over 100 rpm ( lol ) or maybe a flipp'n Tractor.... where ya put em in and just run the Kantankerous ruff runn'n thing anyway.

But in a motorcycle like these SD's where they're tuned and re-tuned and maximizing performance and tuning for smoothness -- NO NOT FOR ME , Champion can stick to bicycle 50cc engines.
Happen to have Iridium's in the SD and in my Honda Ascot v-twin and they're great. Also had a Harley ( i think before iridium's ) that only ran with Nipendenso U groove's - would foul everything else. ND plugs would be one of my first choices.

there - rant over !!!

Funny my Suzuki lawnmower will run the best on them,,,or Bosch,,,the NGK's always foul,,,,,

You will always get what you pay for.

If Champions are indeed that bad, they would be perfect for tractors, especially the diesel ones...

Think I've only bought 6 spark plugs since selling off the last of the 2 stroke dirtbikes 10 years ago.

With that said, what do you use to warrant a spark plug refresh? And do you notice a difference?

I definitely have never been a fan of Champion sparkplugs...
'Denso's or NGK's have always been what I prefered running...

I used to run a pretty hot bridge ported rotary back in the day.

NGK were the only plugs that survived in that motor for any length of time.

champion/autolite/fram = shiat.

Never want to see another snowflake again,,,,,1/2 hour from the speedway n "bike week" it's where I belong,,,,finally got her thinking my way,,just have to do it when I get there I'm going to build a "bunker" for the SD,,, figure two foot thick wall's of concrete with plenty of "re" rod,,,,,,will have to think about it some more,,,,,,,

You would'nt think there's too much to a spark plug.

but I remember being told by those older and wiser than me ,30 years ago, don't bother with Champions.

On another note, just did a major service on the Duke, went down to get some new plugs expecting to pay $20 each,
Well you could have blown me over when the guy behind the counter said,"that'll be $9 for two" (NGK's)
