Hi, Tom, the best way to jump-start your bike is to use a jumper battery and cables, if available, before trying to push start:
1. Your battery connections must be clean and tight.
2. Jumper cables should have 8 or 6 gauge wire.
3. Only use a known good fully charged jumper battery.
4. When jumping from an automobile the engine "MUST" be off.
5. Connect the positive cable first.
6. Let the bike battery charge for 1 minute before starting.
7. Once the bike has started, remove the negative cable first.
8. If no battery is available you can try to push start.
9. Always look for a downhill slope if available.
10. Shift into 2nd gear clutch in and have someone push you then stand up on the footpegs and slam your buttocks into the seat exactly at the same time let the clutch lever out.
