[QUOTE="Nigel Spaxman, post: 107868, member: 2907"] Robert I have read various comments about your ignition system on Woolly. I have pretty much the same thing on my bike. I didn't know you had a Herve Hamon timing disk! I have a really nice strobe light that works with that ignition really well. We should find out what you have been doing for the last 20 years. I have experimented a lot over the last few years. My bike has 8:1 pistons and it is so soft that it never detonates. I have been using timings around 34 degrees full advance. I have found it can tolerate full advance at very slow speeds. I have thought of experimenting with the VOES and using a full advance timing at high vacuum of up to 45 degrees and then having it go back to 34 with less vacuum. I think that might be what yours is doing. I have the programing cable for the dyna ignition so I have been experimenting with different curves. I can strobe time my bike through the ATD hole with some marks on the nylon gear that drives the ignition. [/QUOTE]
