• Do you see spark? If not, check the side stand kill switch. It kills the engine so that you don’t start out with the side stand down. If broken or out of adjustment, it would kill the spark. Check for a broken wire at the side stand switch and coupler. Try moving the side stand kill switch by hand. If that doesn’t work then wire a jumper around the switch to bypass it.
• Is the handlebar kill switch on? Is it shorted out?
• Are you getting power to the coils?
• Check the fuses. How good is the battery? Try a jump start from your car battery.
• Check the operation of the ignition switch and all kill switches with a volt ohmmeter. Check the wiring harness. Did a wire come unplugged? Are all wires clean and with solid connections? Any abraded or pinched wires? Is the bike in neutral and the neutral light is lit up? If no neutral light, check the neutral switch and neutral switch wire on center or side casing. If still no spark, get CDI system and coils checked at the dealers shop.

SOURCE: check the oil

There is a small glass inspection window on the lower flange of the clutch cover (r.h.s.)
Picture of part attached.

Leave bike to cool on the centre stand allowing all oil to drain to sump and inspect window for oil level. It should just cover the window when bike is level. If the window is blackened from oil stains and no oil movement is detected, drain oil, remove clutch cover and clean window from inside with solvent and replace, replace oil with 2200cc oil, Cheers.
