There are usually two methods to check the oil. One is a dipstick and the other is a sight-glass. You should have one or the other somewhere on the side of the engine crankcase. It should be fairly obvious and not require the removal of any body panels. If you can't find a dipstick in the side of the crankcase you will need to get down on your hands and knees and have a look for a sight-glass instead. This will be like a tiny window with a gauge against which you can check the level.

Check to see that power is going into the switch and that power is getting out of the switch. Chances are the switch has gone bad.

If you were to log on to the manufacturer's web site, I think you will be pleasantly surprised as usually one is able to download, by model number, Customer Instruction Manuals, as required.

Just Google the manufacturer's name and follow the links. Make certain you are directed to the manufacturer's web site as some search engines direct you to other sites and they charge for the information that is normally free of charge.

I hope this helps.

Check the actual switch on the handle bar. These can sometimes fail and stick in the on or off position. This could also be a faulty solenoid between the battery and the starter motor. Try this. Find the Solenoid. It's usually a small, black, round barrel shaped block. It will have two small and two large cables attached to the top of it. Disconnect one of the Small wires and reconnect the battery. If it kicks over it is most likely the solenoid. Disconnect the battery. Refit the Small wire then reconnect the battery. If the engine kicks over it could be the actual starter button.
