it was the spark unit all along! (not a shooting thread)

So as of last fall i was having intermitent bike death episodes.

i rebuilt the carbs because they did also need it and i wanted to eliminate the chance of a fuel problem. ?I thought maybe it was better after that but it's old troubles came back.

today i just said "fudge" it im blowing some money and if it don't work then i'm screwed...

so i got me a timing light....wow timing is way off. no advance either. All other ignition chjecks out.

dropped $100 for a used spark controller. timing is back on track and bike runs like it should...hoooray! and POO on those who say that spark units never go bad.

thanks for your time and being patient with my poorly designed posts.

I said they never go bad cause I never seen one that went bad, I always found a bad electrical connection or a bad ground was the fault, and dealers stock them cause people do buy them and troubleshoot by replacing parts, aka parts replacers

To add to MotoF150, often replacing it is what fixed it, IE: the connection was bad. Removing the connection and putting it on a new part fixes the connection. The original part wasn't bad, jus tthe connection.

This happens on a lot of electrical and electronic parts. The Electrical/electronics are fine, a connection has become weak, the problem isolated to a particular module or device. When the device is replaced, the connection becomes good.

My Mercury Dealer replaced the Air Bag control module 2X and replaced all the sensors. On the fourth visit, he had his "best mechanic" check it out. the better mechanic took the dash apart, opened the bulkhead connector (The big, multi connector plug that on the car firewall). He cleaned all the connectors (some were corroded) and put dielectric grease on. the problem (air bag light on) went away. The replaced (under warranty ) 2 airbag computer modules and all the impact sensors because of a loose connection. If this wasn't warranty, it would of cost me a fortune.

Whenever you have an electrical problem, check the connections first. Don't just wiigle or look at them, disconnect them, make sure connectors are tight, no corrosion, etc. I bet 90% of all electrical component replacement was due to a loose/bad connection rather than a burnt out part.
