Re: My Bike Won't Start, HELP!!
Well, sound like either no fuel or no spark as the engine is turning over..
Fuel - is there fuel being delivered? This involves a couple of things (like, is there gas in the tank?!), but more specifically, check for crimped fuel lines, check if the fuel pump is operating, clogged fuel filter, faulty injector(s), etc. There are some relays involved, so those will need a look/test, too.
If fuel is flowing, then check if you've got spark. Pull the plugs and examine them: If they're wet, you know fuel is getting into the cylinders. If no spark, you need to examine the ignition system - and there's quite a number of other things involved if this is the issue..
Hopefully you've got a service manual! Good luck!
