I have some questions:
Can someone tell me something to this sparkplugs?
You can use a NGK plug ER9EH or ER10EH for rvf and vfr 400. Someone here in the forum who use the NGK R847??

How much for a plug in the UK and can you give me a dealer? Graeme France?

No, i make no special engine, i use this plugs in my engine. I got them from my neighbour who work in the ssp 600 world champion chip.
I don´t know that this plugs are so expensive. I found the plugs here in Germany
for 26.-€ But it is too much.

I'm using them (R847-10's), the bike runs like clockwork.

I got mine NOS from Japan for cheap. Once these go I have no more.

Michael: Some 11's on yahoo japan for 40 quid.

Are these surface discharge plugs and if so what is the benefit?

better plugs have a reduced spark time (the total time for a spark to happen), shorter spark time means the fuel will be more compact when it ignites creating a cleaner burn, more energy pushing the piston down and less likely of leaving unburnt fuel to escape out the zorst so generally more efficient

will have to price these up in work !!!
