Acquired this bike recently, and I have no spark. Previous owner gave up on it. I'm not sure what all he tried, but considering he had several older yamaha enduros, I'm guessing he ran into the same roadblock I'm hitting and said screw it.

So, I've already replaced the points and condenser since that is everyone's first suggestion. Even if not THE problem, still good to do. that didn't do it. I've read all the posts I can find on testing this and that, and I'm not finding a solution. I currently have the stator off and have unsoldered the replacement condenser. Everything is sitting in front of me, and I'm ready to start testing again. Anyone willing to give some guidance?

I'll post pics of my test setups in case I'm doing something stupid. :-)

Ready!

My question would be two fold.
Are you looking for guidance or are you looking to solve the problem?

If it were me. I would send the stator, flywheel and coil to DEET.

Then I would reattach those parts and start the bike. No further questions.

By the way.

If you send it in for repair, I test it LIVE with the flywheel and ignition coil. When you get it back, you will know that it produces spark and all the required voltages. All you do is set the timing.

Asco, me and many others have been through this. Deet will send you a working system, just install, time (he gets it very close!) and start.

I'm not usually one to send stuff out, but you have me intrigued. What does it run to have you take a look and what is the turn around time? I know you can't know what it will need, but just looking for a ballpark.

Your restoration would run $170 to $200
Depending on the work load, it would be 1 to 4 weeks.

You send in the stator, flywheel and ignition coil.

I may take you up on that if I don't stumble upon a solution here before too long. I like learning, and I like doing.

It's hard to tell in the photo... condenser wiring looks odd... usually there is more than one wire soldered to the condenser...

Yours looks different? Blue wire soldered and hanging out in space?

looks so good i think i'd just re-solder the condenser wires avoiding then accidentally touching the side & give the new looking points a light wipe with wet & dry paper & try again. set points at a tight 15 thou & wire it straight from the black out of the stator to the top coil & bet she sparks--it looks 'that good'. Of course i've been wrong before lol, so if no spark then come back for plan B. Ultra reliable system generaly. Primary coil--one on right looking at pic-- should have around 1.53 o hms. Ok i'll take some pics of the original workshop sheet from back in the day, but of course when i was there fixing them they never gave any ignition problems--now 45 years later we have to learn all over again.
