If the motorbike is provided with Auto-choke, there is nothing for you to worry about it. When starting in a cold morning, it will automatically reduce the air flow and increase the fuel mixture. Once the engine is in good running condition, it will automatically go to normal position by cutting the power to the solenoid.

• Give kick start; don't use your electric starter in the morning for the first start.
• The engine should start smoothly and after 15 seconds switch off the CHOKE and use the bike in normal conditions.
• When the motorbike fails to start, check the following things.
• Open the petrol tank lid and check the level of the petrol. If it is not enough to be in normal amount turn the petrol cock to the reserve tank position.
• Even at this position the engine doesn't start. Turn off the switch. Remove all naked flames in the vicinity and turn the petrol cock to stop position. Take out the rubber hose between the cock and carburetor. Then turn the petrol cock ON to reserve position. The petrol should flow out freely.
  If not, close it and open the line filter of the petrol cock under it to see for any block.
• When indicator lights are not lighting, check for blown fuses and replace them. Check the oil level in the sump. Then try to start with kicks.
• Fuses are under the seat and on the left side of the cover.

• May be your carburetor is full of petrol. Close the supply valve and drain some of it through the drain screw. Then start it.
• New motorcycles and Scooters are provided with side stand on Engine Cut off Switch. This too can malfunction and prevent your machine from starting.

No progress, wait little time and do the following thing.

• Remove the spark plug and clean them and check their condition. If good fit it in place and proceed with the starting. Faulty clutch switch too can prevent start.

Get a plastic clothe hanger and hold the spark plug near to the engine and start the engine and see if good spark is passing from the plug to the engine.
