Posted June 26, 201410 yr 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
June 26, 201410 yr Author 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
