spokerider Posted March 27, 2009 Report Share Posted March 27, 2009 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?

dan williams Posted March 27, 2009 Report Share Posted March 27, 2009 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.

nzralphy Posted March 29, 2009 Report Share Posted March 29, 2009 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. Quote Link to comment Share on other sites More sharing options...

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. Quote Link to comment Share on other sites More sharing options...
ham2 Posted April 2, 2009 Report Share Posted April 2, 2009 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?!! Quote Link to comment Share on other sites More sharing options...

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. Quote Link to comment Share on other sites More sharing options...
