I was riding to a cruise the other day and just before I got there, my bike broke down next to a service station, no weird noises, no clunks, it just died, so don't think there is any engine damage. Starting the bike sounds normal, it just doesn't start. At first, I thought it was the fuel, so I turned it to reserve and tried starting the bike, still no good. I then opened the tank and it was half full so I turned it back to the normal ON position. I then proceeded to try and start the bike until the battery died. I finally managed to get the bike started using the kick starter but had to keep the throttle open a little to keep it alive, as soon as I let go of the throttle it just died, never have been able to get it started since. As it being a 1 cylinder, its possible that the spark plug could be shot, so I replaced the spark plug, but still no good. There is definitely spark, checked that already. I have removed the carburetor, pulled it apart, seemed pretty clean, no gunk anywhere, removed the main jet and I could clearly see through it. I checked the fuel source, with the tank disconnected, petrol flows when its set to ON or RESERVE so the tank isn't blocked/clogged. After removing the carburetor, I placed my hand on the inlet hole and cranked the engine, there was good suction so this tells me there is good compression and the piston is intact and in good health. So now I'm thinking that the timing is out. I'm hoping you can shed more light on my situation so I can get it resolved without spending much money.
