I have a bike that I just acquired that has been sitting with a full tank of gas for the past few months. I cannot get the bike to start. Sounds like she is about to turnover but does not. Added stabilizer to gas, and opened up clutch with no results. I don't want to take to a shop and I am willing to work on it myself. Any suggestions?
• The first thing to do with ANY engine that has sat for any longer than a couple of months is to dump ALL the fuel in the tank and carb(s). ALL OF IT !! You'll want to refill with some high priced fuel that has fuel system cleaners (Like Chevron with Techron) not becasue you need high-test fuel, but because you need the cleaners. It's ether that or disassemble the carbs and clean out jets you can't find much less see. Your choice. The carb kits alone will cost you about $50 so a tank of high-test is looking pretty good, huh?
• Now the fact that you tried to crank the engine with old fuel has fouled the sparkplugs. All of them. Go buy all new sparkplugs.
• If your bike has a vacuum fuel valve, then you'll also need to set the valve to "Prime".

The bike last ran about 3 weeks ago. I have been suspecting spark plugs and a gas drain, but never have done this to a bike. First one. I will have to purchase a service manual I see.
i have a zzr 600 that will not start have put fresh fuel in it have strong spark but will still not start any ideas
Gas a few months old won't cause you any problems at all. If it has sat for two years - maybe. The spark plugs will never foul just from gas a few months old either, take a look at them when you pull them before you waste money on new ones. If you get the bike running and you think it's a bit rough from old gas try running some stuff called SeaFoam through it. Maybe snake oil but seems to help others.
Check all the fuses too, perhaps your fuel pump is not coming on.
When you say, " Sounds like she is about to turnover" do you mean will not turn over or will not run? If it won't turn over the battery is dead. Assuming it does turn over, check the spark plugs and caps. Gas probably won't go bad after only a few months, but you could drain it and put fresh gas in it. Remove one spark plug and ground it to the engine of the bike, then attempt to start and observe the plug to see if you are getting spark (don't get a shock, it's a nasty jolt).
When did the bike run last?
