Performance plugs

[Allen Pippin]

Has anyone tried Brisk performance spark plugs . It seems I have to re-jet my carb a bit to adapt to the increased performance of the plugs.

I forgot to add it's a 1999 prosport with 107 S&S motor, and super G shorty carb.

Welcome from St. Louis, can not help you with the plugs, but someone will most likely before the day ends.

Put your Champions back in it. Gap them at .038". You will just cause more problem down the road.

There you go!

All the threads I’ve read over the years indicated to go with what Big Dog recommends and don’t mess with all the other fancy spark plugs

No magical spark plugs. Replace with what came stock. Gap .035" to .038"

there may be some small differences, but the spark plugs ignite the fuel that's it, in most cases you are wasting your money - use stock like everyone is saying. Has for carb. adjustment, if needed go to S&S website for how to. if you are looking for go mileage pay attention to the idle mixture adjustment - I get from 150 mile to 180 before hitting reserve
