Shazaam, I may try the bigger gap next time, but throttle response appears fine to me. I'm not overly confident of the ability of the standard coils to produce a big spark across the larger gap. On previous bikes I have used Dyna and Circycle coils especially on highly tuned motors. Had a monstrous CB900 engine once(1984), very high compression big bore kit on it, Standard Ignition would only let it Rev to 6000rpm, platimum tipped plugs added almost another 1000rpm with Circycle coils adding another 1000rpm. In the end to get it to rev out I had to fit a Mistral ignition system exactly the same as used by the Team Bike Endurance team. So I appreciate how important a good ignition system is. I have found that standard road engines aren't to happy with the surface discharge plugs like the Champion A55V and I will reserve those for the 955 race engine |
