I read on http://www.nightrider.com/biketech/spkplghnbook.htm#Red that adding octane boosts can damage the sparkplugs.
Will this happen with optimax?? or just the additives??
If this is the case should I stick to normal unleaded or use optimax on my GS300 MK1?
Also I have a product called Cataclean that helps clean the cat and valves. Should i use this before changing me spark plugs, or after, and thus have nice new clean ones?
Cheers
