The first thing to do now is to see if you have fuel and a spark.
Try and start the bike. Choke on, no throttle. If it does not start take out the plug. Is it wet with fuel?
If yes then you need to check the spark
If no then you may have a fuel blockage.
Next try for a spark regardless of the state f the plug. With the plug out reconnect it to the coil HT cap. Get a set of grips and holding it gently on the while porcelain part of the plug, hold the metal part of the plug against the cylinder head. With the plug touching the engine, try and start the bike. Does the plug spark? What colour is the spark?
If you get a fat blue spark then you need to check your fuel and carb. If you get a yellow weak spark then clean the coil connection, earths and make sure that the plug cap is attached to the lead tightly and not damaged. If you get no spark then you need to trace where the power stops.
So first question to answer are; have I got a good spark and a wet fuel. Use fresh fuel.
Let us know the results of the plug test and then we can move on and eliminate some possible problems.
