So, I am going to start at the beginning so I can try to refresh my own memory and maybe there is a step in here I forgot that would make sense to you guys.
Bought the bike last year, it ran but a little on the rough side. Sat for the winter covered in my shed but seafoam in it over the winter kept the battery inside on a trickle charger but aside from that, probably didn't store it properly.
This spring it started right up, but new gas in it and it dumped out the carbs. Decided to replace the old carbs with the kit from mike along with straight pipes, also from mikes. Put the new carbs and exhaust on, and it seemed to misfire from one cylinder. Almost like it would take a couple seconds to get the right mix to fire...delayed I guess. Then it started running rougher and rougher and dying and eventually wouldn't start at all. This is when I looked at the cam chain tensioner and the valve clearances. Adjust and readjusted following the manual and this post.

Now, the part that I don't understand is yesterday I took the carb bodies off the bike completely and rotated the engine a couple of times with a ratchet I was just desperate for solutions and somebody mentioned vapor lock, thought that maybe with all the ports open and letting the engine rotate a couple of times it would help. Left it as it was and went to the gym for a couple of hours. Came back and put the carb bodies back on and took the plugs out to check if I was getting a spark and I freely gapped the plug with a screwdriver to see the spark better. Checked the other side the same way but like a tard, but the plug back in the engine and tried to start it. It started and stumbled and died. So, i opened the other plug the same way and it started. At this point it had no air filters and no exhaust on it. I buttoned it all back up, exhaust and pods and tried and it was right back to the same issue as before.
Today, I took the pods off, opened the throttle and sprayed starting fluid in it, it will pop but that's it. Took the carb bodies off and sprayed starter fluid into it and same thing. Took the breather assembly off and tried the fluid and it actually sounded like it got a couple revolutions, not just a big bang.
Now, it is making an odd gurgling sound when kicking it, the starter still doesn't want to turn it over with a fully charged, new battery.
I bought some new premium gas and I am going to try to make some kind of temporary fuel bottle so I can control the quality of the gas and be able to check easier if it is getting gas.
So, the last couple of weeks, I have taken the pods off, thought maybe it was to restricted. The kicker was harder than usual, so I don't know why, but I thought I would take the exhaust off. The starter sounded like it was struggling, so I put the battery on a trickle charger for 2 days and no change. Bought an AGM battery from mikes, no change.
Sorry for the long ass post, and thanks again for helping me out. I do appreciate it.
