Hello everybody! I finally got my hands on an engine for my '07 450. Clean, low hrs for what I would say was a reasonable price. Got it all mounted and hooked up, fired once for about 2 seconds, then died. Now, I need some sage advise. Valves in spec, looked in the throttle bore while cranking and the injector is spraying nicely. Pulled the plug and checked spark. Fat blue spark but it doesnt seem often enough and seems kinda sporadic. Checked another plug, same thing. Ohm'd the pulse coil at 97.9ohms, stator at 5ohms all three positions. I have another stator that is around 2ohms for all three. Ive searched this forum and google looking for values for these parts or similar problems but this is hard to describe in a search bar. If I hold WOT while cranking, I can get a backfire loud enough to flatten a small building, but that is it. I'm running off a car battery as the stock battery does not last long enough to do any testing. 12.65v drops to 11.7 volts while cranking. Sorry for the long post, just want to give out all the info I can so that maybe someone can help me. Its been a long two seasons without my baby and I'd love to get a ride in b4 the long Nova Scotia winter sets in.
