06 midnight edition.
Ran great last year when i parked it for the winter. Ive been building a house (literally everything by myself) amd over the winter didnt have time to fire it up at all. I knew the battery would be shot so a few weeks ago bought a new battery for it and suited up...no start. It will crank all day long. If I hold the throttle wide open it will put put put and blow some flames out the exhaust.(unburnt fuel). Pulled a plug and it smelled horrible so i bought new iridium plugs and dismantled the bike enough to get the reserve tank out and cleaned both tanks and fuel pump strainer. Reassembled and same thing.

Plugs are covered with fuel but Spark seems weak to me. Input voltage at the dyna coils is just over 12 volts. Both front and rear cylinders have the weakish spark. When I reassembled it, i dumped some seafoam in first then fresh premium gas. It seems to want to pop and puut more and am getting a little whitish smoke out of the exhaust. Hooked my laptop to the pcv and that still has my map and it was reading throttle position and what not just fine.

Im thinking its either somethings up with the coils and its just not putting out enough energy (but both of them????), there isnt enough compression because it sat for months, or the lifters bled down and so the timing of the valves is off? What should i check next? Btw i dont have a left side dry break so taking the tank off is going to suck if i have to do that again.
I have not changed the oil yet as i figured i wanted to warm it up first. Mentally...I need to be able to ride this beast. Ive been working 7 days a week after work,on my house since september. And we have a road trip planned for next weekend.

When i got the bike ready to put up for the winter i filled it with race gas (no ethanol) and had some stabil in it. But then ended up going on a long ride and had to refil with premium. Parked it like that. Before i took off the tanks and cleaned them i sprayed starting fluid at the filters to no avail then pulled a plug and sprayed in the cylinder. Didnt seem to help. Ive pulled the main fuel line off the rail and let that drain too. Gotta love the ethanol in the fuel these days. The only thing that i didnt remove were the injectors themselves and the rail. Ive got fuel literally pouring out the exhaust joint after cranking on it. Doesnt seem to be a fuel issue to me. And when i had the pump out everything looked pretty clean and ive smelled worse "gas" it sat from the end of october to march

Baks that i cleaned and oiled when i changed the plugs.
Had the battery out twice to swap and starter cables are tight
Had the ground off when pulling the battery box to get at the reserve tank so its freshly tightened. No codes...at least nothing going on with the tack out of the norm.

Oh yea and one of the times checking if it had spark i had one plug out and while looking at it sparking the other plug in the cylinder lit it up and blew flames out the spark plug hole. I also tonight ran and got a new battery again in case something was wrong with the one i bought a few weeks ago. Im thinking tomorrow im going to pull the plugs and put some oil in the cylinders and crank it a few times. And while cranking at full throttle ot does seem to be puffing and popping more and more but nowhere near enough to fire up. Is there a way to test the crank sensor?

So i bypassed the pcv and no change. I put some oil in the cylinders and pushed it down the driveway in gear and no change. Spark seems too weak to me holding a plug on the side of the cylinder. When i crank it over ther is alot of sucking and blowing from the vent tube(which i just have a filter on the end of)

Its never something that simple for me haha. Last night at 830 I pulled a valve cover off. By 10 i had both heads off and had both of the exhaust valves that were seized open working normally again. Today ill polish and smooth out the exhaust ports before i start reassembling it. Thanks guys.

Yea thats why i was pulling my hair out trying to figure out why it wouldnt start. Any otherr piece of equipment that wont start after storage has been bad gas and just needs to be cleaned. I know from now on I will not let it sit so long
