I haven't paid much attention to full over 60% throttle sites in the map below 5000 RPM and likewise I haven't paid muc attention to sites in the map below 40% thottle opening above 6000 RPM because on the road these are pretty much unused sites. The mapping has been done with a SOTP (Seat Of The Pants) Dyno and a thumb operated switch on the handle bar that lets me retard all points on the map by 4 degrees to make comparisons while riding. The map is not perfect yet, but it is reasonably good. Key mods on this bike that effect ignition timing are:įBG Twin Spark Heads (stanard valve sizes but a little work done on inlets)įree flow Spark Italia slip on and FBG headers. Thought some people might be interested in the current ignition map that we are running in the Frankencati.
