[QUOTE="alscomet, post: 18648, member: 260"] I read with interest the article from the Dorset section notes in MPH No741 about Cyril Malem and his approach to setting his valve timing.Can anyone expand on this and what other implications are involved? Does the Ignition timing have to be altered. If Cyril uses the forum can he comment on how the bike runs after the timing mods ,will it still tick over etc,is it easy to start ,fuel consumption? I was speaking to Dick Craven recently who runs a Comet sprinter and he also said that he gets a sparkling performance from his comet without any other aids other than a Mark 2 amal carb and a valve timing sequence that defies the normal set up but he also has to adjust the ignition timing to get the results on his rolling road.He intimated that he may alter the valve timing over a hundered times in a sprint season. Also will this approach work for any motorcycle engine. Alan [/QUOTE]
