2-stroke engines misfire regularly under light loads — sounds more like a flutter or sputter..

My guess would be that at the high end you are running out of torque, resulting in a light-load condition, and that characteristic 2-stroke misfiring is taking place. If you are simply running out of the engine's ability to give more, you might be stuck with this behavior.

Have you had an oil pressure switch replaced recently ? If so the problem is probably the engine wiring loom,what happens is the oil leaks into the loom and ends up at the plugs for the ECU and the coil pack and crank sensors,meaning they all need to be replaced.

Starts but mis fires

I know it sounds too simple but the aircleaner element is worth checking. Even if it looks only a little grey still replace it. Are the spark plugs fouling?? If so I would do the air filter replacement.

Hey I got a serow too, in Thailand. Love the bike but lots of issues, no parts there. Runs great on cool mornings, heats up and acts likes it hits every other cycle. Thought cdi, but fires good when you make it jump to plug. New plug, no change. Carb is not original, going to start there. Think its a 92, think it only 5 gears. Original japan with strange vin. Carb and valve adjust might fix it. Any suggestion?

92 virago 750. Front cylinder runs intermittently. Coil is good. I cleaned carbs. Suspect CDI. Seems to run fine until it warms up. I recently put new Voltage Regulator in. Stator is not shorted. and...

You have to test all the electronics on the bike to figure out if you have a bad CDI box. A CDI box can test good and still be bad. Your problem sounds more like a bad spark plug cap. Unscrew the cap from the end of the wire and take an OHM reading on the cap. If it is higher or lower than 5000 OHMs replace the cap . A plug cap from NGK runs about $5. Replace them both for about $10 it should take care of the problem.
