I have a 1992 CR500 with very weak spark. Just bought the bike, heard it run, but took previous owner FOREVER (like 15 mins worth of kicking) to start it; assumed this was because had not been started since last summer. With the plug out, you have to kick it over VERY hard just to get a weak spark out of the plug. I cannot get it to start and am assuming the weak spark is getting "blown out" by the compression. I even tried "Ether" Starting fluid and it barely popped. Tried starting it from the extremes of a dry cylinder to an extremely wet one bordering on flooded & everything in between. Plug is a new NGK BR8ES and verified plug is good via another ignition source. I would also assume the CDI is okay as those are usually either good or bad, and not "weak" correct ? What could the issue be here ? Ignition Coil ? Pickup/trigger coil ? Stator ? Need some help here.
