I had some electrical issues earlier in season which are all behind me now. Unfortunately I fried my Electronic Advance in the process and had to reinstall the mechanical unit. I still have the pamco Electronic Ignition. Seems that XS650 Direct here in Canada does not carry just the Advance,u need to purchase the entire system, regardless I am stuck with the MikesXS/xs650 direct advance springs with the issues of either to tight or to loose. Is there a recommended rpm that the advance should start. Ive read that it should be approx 1700rpm to approx 3200 rpm at max advance. I noticed that when the electronic advance was installed and working the advance would spool up gradually or progressively and seemed to help smooth out the power curve off the line in low gear. Is that generally what we want to happen with the mechanically springs/weights. I realize the weights should snap back when released but the trick seems to be getting the weights to advance from idle smoothly and progressively. Currently after cutting and stretching the springs back and forth ive been able to adjust the tension so they snap back when released but will advance or open when u add any throttle at all, only issue is I reach max advance at approx 2500 rpm, will this be ok or what issues will I have. I started playing with the advance as I seemed to have a bit of a flat spot between 2000 and 3000 rpm that I could not dial out with carb changes. (my Timing is bang on) I had my advance springs set way to tight I think as I was more concerned that the weights snap back or return .It was like all or nothing ,under 3000 rpm nothing then Wam! It seems better now but still a little flat. Worth mentioning is I have the 17/33 gearing, not sure if 1st gear will be slightly less snappy.Ive never tried the stock 17/34 so cant compare.Any advise would be great. At least im riding my bike now every day, had approx 3-4 weeks with issues and no riding,that really sucked! Also does valves being set to spec have any effect on bottom end.Is been approx 1000 miles since ive checked them.
