[email protected] Posted June 26, 2014 Share Posted June 26, 2014 Hello everybody i just got a 1980 yamaha sr250 i dont have spark, ohm tested the coil its good, pulled little black box ignition unit apart everything seems in order, clean connection to magnet that is close to the "flywheel". Running out of options, help please Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
[email protected] Posted June 26, 2014 Author Share Posted June 26, 2014 I checked the ohms at the primary and secondary testing locations on the coil. 3.5 at the primary/ 19,xxx at the secondary. Coil is good. Don't need spark plug to get spark,, a solid metal key will suffice if your want to get that fouled spark plug (variable) outta the equation. Oh and I have to jump the solenoid currently cuz it's blown. When its in neutral the neutral light does not come on (nor does it ever). When fuel is on, killswitch set to run, bike in neutral, clutch pulled and I push the start button the headlight goes out that's it. But when I jump the solenoid it cranks fine. I've cleaned the starter inside and out and it works now, turned slow or not at all when I got it, took ignition switch and killswitch/start button assembly apart and cleaned contact points. Next ill be heading out to find "points" or cap/rotor setup and clean Sent from my iPhone using Tapatalk Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
blackhat250 Posted June 26, 2014 Share Posted June 26, 2014 Yeh .ignition pick up , must be gapped properly, and try a new bulb in neutral light,, Link to comment Share on other sites More sharing options...
[email protected] Posted June 26, 2014 Author Share Posted June 26, 2014 Ditto on the neutral light, is the ignition pick up the magnet that sits by the flywheel? Has a red an a green wire coming from it? And I pulled cover plate off top left side of motor, just a sprocket chain and probably a cam in there. No parts I the ignition system that could cause a no spark scenario Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...

[email protected] Posted June 27, 2014 Author Share Posted June 27, 2014 Still no spark, wasn't able to check the coil behind the flywheel cuz I need a pulley puller. I guess it's probably called a flywheel puller for a motorcycle, I just know there are some coils behind there and probably the reason I don't have spark.
