Thanks all



Oh, any comments on preferred brand, cheapest supplier, iridium and such like are all gratefully received!

I thought you'd have learned from the 'which oil' post, this'll be the same.

I got the std NGK plugs,, I tried the iridium ones in my class b bike and it took me 3 days to work out what was causing the misfire. but I think other people use them with no problems.
