Bike Wont Start (been sitting 2 months)
 

Okay so here's some background on the situation I'm in.. I broke my ankle a little over 2 months ago so my bikes been sitting in the garage on stands with a cover over it and a full gas tank. I know how expensive batteries are and I didn't want mine to die throughout the time the bike would be sitting so my thought process was that I would start the bike once a week and let it warm up. So I did this for about 3 weeks and its started up just fine every time. After the third time I wasn't able to get back to the bike for 2 weeks and when I finally went to start the bike the ignition would just crank and crank as if it were trying to start but never did fire up the bike.

After some research I learned how running a bike for short periods of times as I did can be harmful and since then I have been keeping the battery charged by charging it once every 1-2 weeks on a charger (I know the battery is good, and has a full charge). From my research I've read that condensation can build up in the gas tank from running the bike for short periods of time if it is just sitting but I find it hard to believe that this is the reason it won't start since it has a full tank, has been in a garage, and the weather has been neither hot or cold in Texas for the time it's been sitting. I also stirred up the gas a little bit and tried to start it with no luck. I didn't have any sort of stabilizer in the bike but plan on running some through when I get it started.

What are some things that could be causing the bike not to start? Could the spark plugs have gone bad during the time its has been sitting? Why would that happen if so? And what are some other issues or similar experiences that could be causing this problem?

Thank you for your time and I hope together we can diagnose this issue because I'm healed up now and anxious to ride!

PROBLEM SOLVED!

I realized my fuel pump wasn't priming when I would turn the ignition and starter on so I wen't through and checked anything that had to do with the system. Turns out that my fuel pump relay was corroded a bit to the point where is wasn't working. I ended up spraying a bit of Deoxit contact cleaner on each of the relay switches and the harnesses they plug into. After putting them back in and turning the ignition and starter to the on position the fuel pump immediately primed and I knew it was going to start. And it did.
