Hi all I am using NGK B8's at present and did a 30-40 mile run today. I have started to wein the bike off pre-mix and had only 100:1 ratio approx in the tank now I guess but I still eating spark plugs. During the run today which was around country lanes at approx 3000rpm 50-60mph the bike started to miss and run rough so I stopped and found nothing wrong after a quick look around. The bike would not run clean so I changed the plugs and hey presto back perfect again all the way home.

Any ideas?

I have the mixture airscrew out 1 1/2 turns at present but the plug looks quite black??
The oil pump is set with a bit of slack in the cable and I think I am not smoking too much if a damp bombfire at idle is right lol

Thanks Paul
