I’m gonna butt my head into a 450 thread for a hot second, because we’re talking the same plugs.
Anyone ever used one of these?

Seems low risk for $30 (HF I think has it for cheaper) and from what I understand people used to use these all the time?
Hoping it can help recover some of my spark plugs from when I was still getting the bike tuned in.

My Dad used to have one of those back in the day and they work fine to a point, but fouled plugs never clean up completely so it doesn't work on all plugs regardless of condition. Does help clean up plugs that were just heavily carboned up due to richness or light oil burning
