Hi just thought I'd relay my woes. I have had my bike for 29 years I rebuilt the engine a couple times and the transmission once. Most work I have done myself or with the help of a friend from time to time but nothing professional. The form here has been helpful on more than one occasion and most times I read and do not post any items or give any advice. That said I would like to share my present situation with my bike that I had recently professionally restored. One would expect to have many miles of enjoyment with such quality workmenship and expertise. In comes the electrical demon and the spark from hell. I'm riding along at about 35 mph minding my own business when the machine just lost power like I turned the key off for just a couple of seconds. Just enough to make me nervous and I turned off the main drag and when I did the bike lost power again. I'm coasting up the road working the throttle wondering what the hell happened when she let out one huge backfire and that was it no more go. Now I'm on the side of the road kicking away not even a burp. I stop and start doing the checks, fuel, wires anything to see if I could see something, anything! loose wire, but nothing. I try the bike again and wow she started sounded good running smooth normal rev up no problem then it just shut off like I turned the key off. It ran about one minute, I wiuld try to start it agin but no go however I noticed if I waited about 10 mimutes or so it would start run 1 minute and shutoff thats all I could get her to do. Nothing I could see by eye to cause this condition. In the truck and back to my garage to see if I can figure what the problem is. Well I found out what is happening when I did the spark test. Sometimes when I roll the engine over it sparks and most times it doesn't. So what could the problem be all new gear so let the tests begin. I'm running sparx ignition black box pick-up plate and magnets also HO alternator and regulator/rectifier made by sparx.Coil pack is electronic manufactured by crane cams so all is knew but here I am with intermitten spark so where to start. I checked and tested all parts with multi meter, low voltage tester and a continuity tester. I found nothing conclusive to point to the black box coils or pick-up plate all readings normal as I have determined by paperwork specs or things I have read in articiles like here on the form. So what is causing this condition. Battery is fully charged and reads about 12.5 volts with meter. Everything reads ok and yet the problem is there. Most times with electrics you end up changing out parts and sometimes you might get it on the first try but my luck I'll change out all three pieces and still have the problem. So new or old when it comes to electrics bad things can happen. Is anyone out there running the new pazon ignition system it looks very impressive and has some nice features but very expensive. 7.5 year warranty, circuit protection, built-in strobe on pick-up plate nice. Anyone? and if so let us know how it works out I have found rita or boyer trouble will follow seems like sparx is no different when it comes to defective parts. There is 2500 miles on bike since rebuild and I wasn't real easy on her gettn' there I had lots of fun and more to come when I solve this spark issue they are GREAT BIKES keep them running.... ride like the wind....
