All that can generally be described in one word. BULL****. Any spark plug can only ignite what is in the cylinder. The manufacturers recommended plugs are all you need.

The change in your performance will be astounding.
How? They can only ignite the fuel in the bloody cylinder, they can't control it. I would be totally ****ed off if i bought a box of ten plugs for any of my vehicles and it cost me more than £15.00.

Why did you start this thread John
to seek opinions on the types of spark plug people prefer

I have a 1987 YZ80 which has had the same NGK plug in it since we bought it about 2 years ago. Admittedly i don't use it for commuting but still my old Fizzy used more than that, which may have been down to the Castrol R I put through it because of the smell, arrr the smell of castrol R 2 stroke

Well I've known at least one issue where someone has fitted super duper plugs with a super fine tip - which broke off and ruined a cylinder - it was on a turbocharged bike - but still - I'm sure it would have been fine with the standard type plugs.
i have champion plugs in mine which came as part of a 'service kit' that i bought not had any problems with them, although as they are a multi tip type plug i have been advised to change them to single tip as i run lpg and the single tip gives less problems (according to the lpg fitter) although so far 25,000 miles on and no problems with the champions

fitted ngk iridium seems to be an improvement or maybe old plugs were knackered
