Hi,

I have got new plugs - still a slight misfire! Yes I put some more petrol in...

Jeff and Wayne - would you mind having a quick look at it when you come by to pick me up for the track day? It has a slight misfire at around 7000 rpm, and just feels not quite right at the top end.

Halfords near me didn't have the battery, they had one called YT4LB - could that be it?

Cheers, Mat.
