[QUOTE="Nigel Spaxman, post: 91918, member: 2907"] Mike I have never checked to find out at what vacuum level my VOS grounds. I realize I might be able to benefit by adjusting that and I have talked to Robert about it, but to begin with I have assumed that having it set as it comes which must be right for the Harley engines is probably good enough. My engine never has the slightest tendency to ping. I tend to run the 94 gas almost always though because I prefer not to have Ethanol in my gas. The odd time when I ran it o 87 it hardly seemed to make any difference. That leads me to believe that I could have the VOS ground at a bit lower vacuum and it would still be OK. That way even at the higher cruising speed and moderate acceleration it would still remain at full advance. Robert installed a light so he would know when his VOC was grounding, that way he could discover when it was actually working during normal riding. I haven't even had time to instal this light, I have had so many more important things to do with my bike. [/QUOTE]
