90% of no spark is caused by the CDI Charge Coil in the Stator. Below you will find the data on how to test the stator. First, ensure the on/off switches are on and that the remote is in the on position (if equipped with remote). The stator is what provides spark for your gokart, atv and scooter. The stator is located on engine side housing, where a 5 wire unit is coming form engine block. Remove this cover and you will find the stator inside. FYI the stator is made up of several coils. One coil is the trigger coil. The second coil is a charge coil which makes electricity to make the CDI box fire. The third coil is the coil unit which charges the battery and powers the lights. 1) If it is a 1 wire coil, it needs to be grounded to the frame to fire the spark plug. 2) If it is a 2 wire coil and it fires when not grounded to the frame, the coil is defective. 3) We do NOT count the large wire going to the spark plug. This wire is called high tension. 4) With these steps complete, we can now test the ohms from the stator. a. There will be 5 wires coming out of this unit. One wire will be blue, with a yellow/or white stripe. This is the trigger coil and should show an ohms reading of 120. The decimal point can be any place. It will still be 120. If way under 120, the reading is beyond 150 or there is no reading, the stator needs replaced. b. Next, go to the red wire with black stripe. It should read 400 ohms. If below 350, above 500 or no reading, the stator needs replaced.

Check For Spark: Apply brake and turn key to the “on” position. Remove the spark plug and ground the “hex” shoulder to a bare metal engine part. Be sure no gasoline is near this source of ignition. Crank the engine by pulling the rope or turning the key. You should see a blue spark jump across the plug gap. If you have a good hot spark, skip to the gas flow section. If the spark is yellow or weak, first try a new spark plug. (NGK CR7HS is the stock spark plug for most units.) Do not try to clean the old one. Set the new plug gap to the proper spec (usually 0.030") and check for spark again. If no spark, please contact us for further assistance. Check For Gas Flow: Remove fuel line from the carburetor, hold it over a container and check for gas flow. Flow should be the full stream of the line size. If fuel is flowing freely, then the trouble is in the carburetor. If there is little or no gas flow, remove the gas cap and see what happens. If gas flow increases you will need to drill a small hole (1/16") in the top of the gas cap for venting. If there is no improvement when gas cap is removed, then the trouble could be in the fuel line shut off at the gas tank. Ensure there is no obstruction in the fuel line.

Check the valve stem core seat and make sure that it is tight. If it is tight, go to a local parts store or hardware store and purchase a can of tube tire sealer, and use according to directions. We use a product called Green Slim Tire Sealant.

Find the 17 digit Vin # that is located on your vehicle. Scooter: located on the steering stem. The Vin # starts with ‘L2B’, ‘L9B”, something on that order. Once you have the 17 digit Vin #, email the information to admin@smmotors.net or sales@smmotors.net You will receive a response back from your email either the same day or the next day, letting you know what steps need to be taken at our end and when you should be expecting the Title. Once we have the Title prepared and the Bill of Sale to the Notary, they are mailed out. If five business days have gone by and you have not heard from us, please contact us again to find out what is happening with your Title.
