I charged it up over night, got it to crank pretty hard, but it wont turn over.. It wasnt starting before so i changed the plugs thinking that was the problem, still not turning over..
before what it did was it started then slowly died, then didnt start again when i went to start it up in the winter one day. maybe the idle control is the problem? because it was idling at high RPMs last season, so i turned it down, is it possible i turned the idle control too low? the fuel pump is priming and im pretty sure the combustion chamber is getting fuel.. by the time i get this thing running its going to be COVERED in spiders, i just know it =[

your terminology is all over the place .

cranked over =starter is spinning the motor?
turn over =the motor starting?
still not turning over then it started ?
then it didn't start again.Do you mean it wont crank over or it wont turn over or it wont start?


lets try this.
While pushing the start button the motor turns over yet wont start(run)


yes your idle setting can cause trouble.Usually it will start (run) with some throttle.

I've seen many bikes while pushing the start button turn over yet not start because of a weak battery.

Id start by charging the battery fully then cleaning and tightening the battery posts and connections.
-just saw your edit, that's a good sign.

idle set too low can make getting the engine to fire, especially when its cold, difficult if not impossible, try adding just a little bit to the idle screw, like 1/4 turn or less
is the run switch in the on position? flick it back an forth a few times then go to run and try again, I think it was the F4Is that would crank but not fire with the switch in the off position...

EGV isnt a big place i might be able to swing by and give you a hand if it keeps giving you trouble.

sorry i haven't updated guys, been kinda busy mixed with kinda lazy. maybe i should get the battery tested? anywhere that does it for free? I just don't want to put money into the bike if its not necessary. and if the batterys not the issue, im out how ever many bucks

Sorry for taking so long to reply guys, been kinda busy. Anyways, had a mechanic friend come over with his battery tester and test the battery while starting. got about 10.4 volts. Checked the coils, they work, spark plugs are brand new, and now injectors don't seem to be spraying anymore, could that be because the fuel pump has too much pressure? And anyone know if there's a fuel pressure release valve or something for it? I've been researching online for similar problems and been finding so many different answers, don't even know where to look now. =[

fuel pressure from the pump will not stop an injector, i would look at the PC2 and the relavitely low voltage of 10.4 (was that when you were cranking?)
90 miles per tank is unacceptably low, im surprised it even runs with it feeding more than double the fuel of normal.
while youre in there check all of the fuses with a meter as well as checking the stop/run switch at the handle bar

check what ressurection said as well.

also for a list of possible relevant symptoms

- Bike ran really rich, gets pretty bad mileage about 90 miles a tank
- there was a coolant leak last riding season that I got rid of, but now it seems to have returned.
- Was going pretty slow on take off from stand still.
- Has a power commander II, I was told by a honda tech to disconnect it from the bike last year and that would fix the rich fuel problem, couldn't really get it come off though as the wires are wrapped pretty good with the rest of the wires, so I left it on.

If theres anything else I remember, Ill be sure to add it in later.

Thanks again guys

check tip sensor.

check that the fuel lines are truly plugged ALL the way into their quick disconnect fittings.

check the wire plug fittings.

Good luck

Okay so update, took the battery to batteries plus to get it checked (again) and the voltage tested fine, I asked him if his load tester tested amps, and he said no. So I asked the guy there if I could buy the battery and if that's not the problem return it. Guy says he needs to ask his manager, manager came out, used a different tester to test cranking amps (which kinda pissed me off because it was right next to the original volt tester) and it failed. So now I've got a new battery in the bike charging. We'll see how this turns out in a little bit. Ill keep you guys updated!

Also food for thought remove the PC get it started then rhook the PC. had that issue with mine PC decided to just go crazy.
