March 27, 200917 yr If a plug becomes oil fouled, or fouled with sooty deposits, what is your preferred method of cleaning it, or, do you just discard it and buy another? Realistically, a fouled plug should be able to be cleaned and be " good as new" provided the electrode is not worn....... Soak in solvent? Blast with sand blaster? Other?
March 27, 200917 yr When I was a poor teenager I'd bead blast them at the machine shop I worked at. Seriously though given the cost of everything else on a trials bike the plugs are the cheapest thing on the bike. Easiest to just buy new.
March 27, 200917 yr not much point i just buy a few plugs and change it every 6-7 trials to be on the safe side but dont try a fancy on get standerd ive had a fer problems with the fancy
March 29, 200917 yr Solvent and a brass brush - you do not want to scratch the smooth surface of a plug. No sandpaper or sand blasting!..... Because a couple of grains that could drop out of a newly cleaned plug could easily scratch the bore.

Yes, it probably IS easier to just buy new, but, I really do not like discarding things that are perfectly good, with the *cost factor* being a secondary reason. Just my humble nature I suppose........ Yup, I use solvent to soak the tip in and wire brush followed by compressed air.
April 2, 200917 yr Had a Suzuki Er trail bike which ,after just a few of days of inactivity,would 'demand' a brand new plug to start it. No amount of plug cleaning (solvent,brass brush or even autoclave) could coax it into firing up. I even tried to fool it by putting a cleaned plug into a new cardboard box but it knew..it just knew?!!

I have tried 2 new plugs but both oiled up so i have just went back to the old plug which is years old. Runs sweet.
