My Bear is smoking slightly when u romp on it and when it first starts it will give out a puff of smoke...
First- I do see your last sentence in this post, so don't take this too harsh or too personal...
This is a mechanical problem. You can pour anything you want in there, it isn't going to fix the problem. It might not make it explode right away, but it isn't going to fix it either.

anybody tried running lucas oil stabilizer or stp oiltreatment if so how good does it work?
Don't do it. It does extremely well in a laboratory environment, which really isn't quite what's going on inside your engine. It also does exceptionally poorly in the example posted by Bob and linked to by mud_dog450, but again that isn't quite what's happening in the motor. (Give it strong consideration however when considering SOME transmission designs and lots of front/rear end designs, very close but still not "the same".) My belief is that while it doesn't fail as miserably in an engine as it does in Bob's test, it's less of something that "you should do to an engine" and more of something that "you can get away with doing to most engines".

and how much did u use? im jus tryin to get the most out before i have to break the wallet and rebuild
I use NONE... A lot of people don't believe this, and it's always easy to hope for a miracle, but really fresh clean engine oil does an exceptional job of lubricating engines. What is an addative going to do? Really... when you consider all the parts of the engine that interact in different ways with the engine oil, none of which can be "shorted" of anything, what can an addative possibly do without blowing something else up?

I hear you there. Trouble is, if it's making smoke, the defect is in the top end. Continuing to push it "till the end" is asking for a simple honing with a hand drill to turn into a machine shop overbore. A machine shop overbore to turn into a replacement cylinder. A valve guide/seal replacement to turn into a new cylinder head. It really isn't saving money or buying time in the long run.
Now, as for what's wrong with the bike-
Brand new rings aren't "seated right" for a long, long time, yet they don't smoke when you buy a brand new bike. Why should the smoke be considered acceptable now? The answer is that if it's coming from the rings, it isn't acceptable after a minute or two to burn off the oil that you slathered all over the cylinder, pistons, and rings for assembly purposes.
Immediate smoke on startup doesn't point me to rings. That points me to valves/valve seals. I don't know this engine specifically to know how the head is designed, if this is realistic, if there's oil to "leak down" past them or not when the machine's shut off. Worth considering.
Smoke on WOT leads me towards rings and/or cylinder sealing issues. These like I say are not "break in" issues at this point. They are there or they are not.
I can't say since I'm not there, and I don't know you from adam to guess at your observations, so don't take this as such, but is it possible that the time you are seeing the smoke isn't exactly coinsiding with these events? Could it be as simple as oil residue burning off of the inside of the pipe from the original ring failure?
I know you said that "you can't just do nothing", but in my personal best judgement, based on the information from your posts in this thread only, and guessing at the likelyhood of many variables (nothing wrong, valve seals failed, piston rings cracked, cylinder scored on installation, jug too worn for new rings, mud in lower end, and lord knows what else), but barring a teardown, my best advice is to be absolutely sure there's a good quality brand name oil in there. That's it. Well, that and if you have a chance perhaps another good ride on it to nail down if it's getting worse, staying the same, or if (knock on wood) it's crud in the pipe, maybe it'll pass in that time.
