Meh.
If it was going fine a few weeks ago, think about what might've happened in between. It's fairly obvious it hasn't suddenly developed some mechanical problem while sitting there. It needs fuel, air, a spark, and compression. You can rule out compression being an issue, and it should be getting air (unless a mouse has taken up residence in the airbox).

Is it sitting out in the weather, or was it out in the wet last time you rode it? If so, then it may have water in the fuel (which doesn't burn too well unless the combustion thing is already well under way), or it may have water and/or corrosion pissing about with the flow of electrons into the sparking plugs. This could be summat like a short to ground in the ignition circuit, or it could be summat like a sidestand switch malfunctioning (unlikely, if it's turning over on the starter).

It sits in the garage, No corrosion that I can see...
Will try and check out the rest.

You could always swap with that Yamaha you have there, he almost owned a year ago....

one thing at a time.... pull a plug and see if it actually has spark.... actually pull at least two... a coil may be dead.

check all your fuses

get back to me on how you go... then we can go from there.
