Hi Jim, I have a fourwheeler and I want to add Sea Foam Motor Treatment to the oil crankcase. It has a wet clutch. Will that affect it in any way? I would run it in neutral for a little bit to clean it out, but I want to know if it could damage the internals. It’s a 05 Yamaha Raptor 350cc.
You can definitely use Sea Foam in your four wheeler with a wet clutch. It won’t harm it in any way and will help to clean up the crankcase.
