Yz426 with a wr426 stator,flywheel but no spark??

SOURCE: 83 yamaha tt600e no spark

The CDI unit on the 83 model (TT600) is located under the fuel tank and suffers from heat
exposure.The solution is to get specialist help to open up the sealed CDI unit and repair/
replace internal connections (which are readily available electronic components)
When you re-install it put some heat shielding material there to protect it and this
will be OK as repair will utilise stronger parts,I think.
Later models have the CDI unit moved to the head-stem area.

(this info from a Non-mechanic who remembers what was done to his TT in Australia, many years
ago)

G'day i am a . YZ 125 j ...lets see now! You could perform these tests yourself.Check your plug CAP,if in doubt replace it with a new one. Take the below ohm figures and see if they match up. Pulse coil: white/blue and white/red= 310 ohms. low speed coil: Green/white and Black/red= 900 ohms. high speed coil: Green/blue and black= 55 ohms. hope this has helped in some way to helping you solve your problem.If it has please leave feed back.Ride hard , see ya,Tabbycat

I have a 83 DR 250 and i'm not getting enough voltage to create a spark, all I can suggest is that you check your battery and make sure its at full flavour. Check and see if you are getting any voltage prior to the ignition coil (should be 18-35v). If you suspect battery then try clutching it as the alternator moving faster might give you enough to get her going. Also check all your connections and earths. Earth wires are often overlooked and can cause you just as many problems as the actives. So give that a go and get back to me mate. Cheers
