Hey guys, So I've rebuilt, rewired, and reassembled this 81 650H over the past three months. I can get it to fire up, but it won't stay running.
Back story - I bought the bike in pieces from a guy who was running chopped straight pipes and basically wire mesh as carb filters.
Here's more info about my engine rebuild. More info about my wiring. And some other advice which I've followed.
What I've done
Specs
Carb Set: 1981 so BS34 (I think)
Airbox: K&N
Iginition: Boyer Blue Box
Exhaust: Emgo shorty reverse megaphones
Main Jet: 135
Pilot Jet: 42.5
Needle: stock (I think)
Needle Position: stock (I think)
Mix screw: 3 turns out
My 99 problems
Over the course of trying to get this thing running, I've kicked like a thousand time, so my leg is tired, that's my first problem. I'm getting a really strong kickback every now and then, I jump on it with all my weight and just about the tip the bike over and kicker stay upright, regain my composure, try it again, and it kicks fine.
I'm also seeing some oil seeping from somewhere in the vicinity of my head gasket which I just replaced.
After a few kicks the it'll fire up and run for about 4 seconds, then die. If I give it any gas it dies right away. If I give it gas while kicking it, it won't start at all. I don't know if it sounds like its supposed to, because I've never heard the bike run before. Also, over the course of messing with the air mixture I got some flames shooting out of the exhaust, which was exciting, but probably not good.
Lets hear it boys (or girls, if there are any in this forum).

What I've done
- Checked compression, 150PSI in both cylinders.
- Done my best with my timing, (without a timing light).
- Synced my carbs using the paper strip method.
- Adjusted the valve lash.
- Got clean gas, a clean tank and a replaced fuel filter.
- Made sure none of my jets are clogged and my float bowls are clean.
- Retorqued my head bolts, which some how got pretty loose.
- Felt the pipes and both get warm, so it's running on both cylinders.
- Messed with my idle settings back, to no avail.
- Cleaned my carbs again, just for good measure.
