[QUOTE="timetraveller, post: 3188, member: 456"] Thanks for that information Pete. This is just what we need, ie some facts. However, how much retard does your electronic advance and retard system give and what are its characteristics? Certainly my bike on 9:1 pinks at mid range revs if I open it up suddenly but I have not checked at what revs it achieves full advance. I better do that once it is back together. That is timed at 38/39º and run on unleaded plus Millers octane booster and lead replacement. Roy Robertson's racer with twin plugs and squish bands seems to work well with full advance in the 18º to 24º range. That is on super unleaded and Avgas with a 50/50 mix. Is there anyone on this forum who has done proper tests on a rolling road or similar bit of kit who is prepared to pass on their results? :) [/QUOTE]
