My SLR has developed a misfire at 7000rpm, first noticed at Donington on friday. It got worse, and was pretty violent (as if it had hit the rev limiter).
I changed the plugs today (Champion RC7YCC) and it appears to have improved it a bit, but it is still there.
Compression test showed 220-210-235-225 psi, so no huge problems indicated, although there is a tiny bit of sludge in the header tank. Water temperature is fine, oil pressure is fine too.
HT leads, etc, all look fine. Any other ideas? It needs to be in top shape for Curborough.....
Thanks for your help.
