Monster 620i.

Haynes say it's a Champion RA4HC. As we're running hotter, is this still the one to use?

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.

I'm saying nowt this time, as he chose to ignore my advice.

I use NGK tho'. You should be OK with the tyres as we all use the same.

Still using up my stock of NGK EVs

Just put the ones in out of the MOWER they never missfire.

Remember that if you switch to iridium you need to use a larger gap than the same standard plug.

I'm still keen on the plasma discharge plugs with NO earth electrode but they are horrifically expensive....
