I took out one of the plugs and it wasnt dripping of gasoline, but it did have a strong gas smell on it. Is that a bad sign?

I have spent the last few weeks trying to figure out why my bike wont start and I went through all of the possible issues, I think:

-replaced old plugs
-replaced old battery
-replaced old FPR
-replaced air filter (just because it was old)

She has about 15k miles, and Its been sitting up for the cold weather for the past 4 months. Im wondering if the engine is possibly flooded because of this? I heard that if the bike sits up too long, then the oil and gas can get mixed up with each other and affects the plugs. Is that true?

note: Damn I just noticed......"Flooded"

 

Whats the problem? Is it cranking but not starting? Will it crank? Is the kill switch in the "run" position? Is the fuel pump priming? Is it in neutral? Is it up on a stand? If it is, put the kick stand down. Did you hook everything back up afterwards? (hoses, connectors, sensors, ect.) Are any of the hoses pinched? Is the headlight hooked up? Specifically the BAS.

 

Yeah its cranking when I push the ignition, but just not starting. The Kill Switch is good, fuel priming is good, Its in neutral, the stand is down, Everything is hooked up the way it was originally, no pinched hoses. The lights are all hooked up and bright.

Would changing the old oil and siphoning out the old gas help if it was possibly flooded?

 

puttin in fresh gas won't hurt. And an oil change is always a good idea, although it won't solve your problem. (fresh gas might) So you can hear your pump prime when you turn the key? We racked our brains for a week tryin to help another member that swore his pump was priming, but wasn't. Turned out to be the BAS.

 

I dont know how long it takes gas or oil to go bad, but they both have been sitting in the bike for months, which is why I thought it might be the issue.

But yeah, when I turn the key, i can hear the pump prime loud and clear (the high pitched buzzing sound?). Forgive my ignorance but I dont know what the BAS is. Where do I locate it and how do I check it?

 

On 600rr if it is flooded you have to hold the throttle wide open and crank it. They say you will go through a full battery charge before it finally starts. Just happened on my old 600rr and sure as **** it worked. After about a hour of cranking on it it started up and blew all the excess **** out as soon as it started. Worth a try?

 

Gas will go 'bad' in a few months. So if it was sitting for 4 months with unstabilized gas, yeah you need to drain it and put in new fuel.

BAS: Bank Angle Sensor. Its a safety in newer bikes designed to cut the fuel supply in case the bike is tipped over, like in a crash. That way the bike doesn't add fuel to a fire, literally.

Search in the F4i section for info on the BAS, how to test it and how to bypass it.

 

Update: Well weird enough...after spending all this time trying to figure out the issue and not seeing any results, I was just about to say **** it and give up all together. So after a couple of weeks of wrecking my brain, I just went outside just to give a last-ditch effort to start the bike and guess what?............It just cranks right up!!!!!!!!

WTF???!!!!!!

But I guess there's no reason to complain. I do appreciate all you guys for giving all of your input though. I still dont know what the problem could have been or what the solution was, but I will keep everything y'all said in mind in the future.
