Running weird.
WEll i wont be able to get on the computer again untill tommorow night but i will ask now anyway. I got my forks on put in radiator fluid and started the bike.
The first problem i had was fuel was like coming really fast out of the overflow. I didnt have time to take it apart as i was doing it before work... yes i work. . Anyway when i got home i clean out the carb again, checked for stuck floats and reassmbled. It didnt leak when i put it back together. After i turned it off it started to leak again though. So then i turned it on once more to do the first 10 minutes of the break in process.
The one thing i noticed was that the bike was very rough running at low rpm's. It was fine at mid but horrible at low, it would bog and put out alot of white smoke.
Im thinking the problem is still the floats. I think the float level is too high putting to much gas into the carb, when i am at low speed the engine bogs and puts out white smoke because too much fuel is getting into the engine. Am i correct or am i way off? If i am correct all i have to do it adjust the floats to rest a bit more down so their is less fuel in the carb right??
thanks for any help.
By the way, the bike started 2nd kick cold, no choke, after a new top end was put on. Was anyone elese able to do it in one? Just curious.

When the carb overflowed you should have checked the float height then. It's not a make it a little lower thing.... It's a measure thing.
Also check your float needle and seat for wear and gunk.
White smoke sounds like water. Are you sure you torqued the head bolts correctly?

How apart has this bike been over the past six (only six?) months?
White is water.
It's leaking.
If you have antifreeze in it, you will smell it. Don't have AF in it? PUT
some in. THEN you'll smell it.
A whatnot just for you:
'am i way off?'
Yep.

If you really had "white smoke" you will still have white smoke. Too much fuel does not cause "white smoke". Get her running strong and crisp and check for the dreaded white smoke. If she is blowing white smoke do not put off getting the problem fixed.

well it fixed the fuel leaking out of the overflow problem. The smoke is not white but maybe more of a grey. I put the carb on the bike and ran it with a new plug. It idles a bit higher than before i changed out the needle and now the bike is not smooth in any part of the rpm range. I cant figure out what is wrong. The float level is correct but i still dont know what the problem could be. I think im gonna take it to the shop next week so that way i can ride, thanks for all your help.

Cfspawn - normally it is the head (or head gasket area) that leaks. Combustion gas pressure verses improperly torqued head, over stressed head bolts/studs or a damaged sealing gasket can be the basis for trouble.
On an engine which has been in service quite a while the head stay to frame mount can also contribute to the head leaking due to stresses associated with frame flex and vibration induced stress which is transmitted into the head.
I believe most knowledgable people will torque all the lower engine mounts and swing arm and save the cylinder head mount to frame for last to keep the initial head stress point near zero.
I would guess it is unusual for the base cylinder gasket to leak for a variety of reasons - low cooling system pressure only - not a lot of thermal differential - etc.

Ryan, check the intake manifold for leaks & re-torque.
