Spark cutting out? Check and make sure you don't have rust under the ignition coil. They need a battery for the spark to work correctly. The KLT200 and 250 both have a wet stator. It's covered in oil and should be. Make sure you have clean connections at each plug. Make sure the kill switch isn't dirty and vibrating or something silly.
I just wanna go fast. If your not first, your last!!
