Have 1976 Rd400. Lost spark on left bank while riding. The bike has a CDI Ignition. Not sure what brand. Will try to post a picture.
Was riding Sunday. Everything was fine. Bike has been perfect. Monday was caught in a 3 minute rain show. Went and put bike up. Today problem occurred
Checked coil with ohm meter. Checks out ok. Changed plug. Still no spark. Pulled Stator cover. Everything looks in place and dry. Checked fuses and all are good. Battery is good.
Please help. Want to take the bike to the Harvest Classic Vintage BikeFestival in LukenbachTexas on October 18-19.
As Always thank you Bubba
Sorry can't figure out how to post pictures using my phone
With iPhone email them to yourself
Select small or med size. Open and Save then.
They will post. Your format is too large
this is it
Orange wire has never been attached
Could be a bad pickup, you should swap the wires leading into the coils and see if the no spark follows. I had a magnet in the rotor portion on a hall effect fall out one time and killed one side of my xs650. Those pickups do fail, you can probably find the ohm value and check it that way to
thats not a cdi, thats a points replacement. single dual lead coil? try swapping plug wires. if it doesn't move spark from cyl to the other, bad pickup or bad plug wire.
tried swapping wires no luck. Seems to be a Martek Products inc unit. When it comes to electrical systems Im lost. Ground wires look good. All connections look good. HELP !!!! lol
Thanks , Bubba
prob a bad pickup them.
M, where can I find a pick up? Excuse my lack of knowledge I don't even know where they r located. So lost with the electrical side.
I just went through this with a different brand unit.

The pickups are those two black things -they sense the engine rotation for the spark - one for each cylinder. I was able to swap mine around to prove it was a pickup, the 'no spark' issue I had moved with the pickup. In order to do this, you *must* be able to set the timing, it will change as soon as you remove a pickup.
Once I proved it was a pickup, I bought a new unit for a different bike (with near certainty it was the same...) and then grafted the new pickup onto my iggy. Soldering capability is also a must.
Good luck, it's your opportunity to learn your ignition and conquer fear of things electrical.

for a martek? not sure, but id look on the uk aircooled owners club group on FB. if not, might want to consider a dyna from nick. not cheap but really good.
Thanks for the help. Could not find any parts for the Martek. I ordered a CDI kit from Economy.
Thanks, Bubba
dyna s kits are easy to plug and play. Just need to follow the instructions to a T
