Well Mike just pointed out that I have an auto cam chain adjuster..........SO looks like itll NEED to be torn down just to do the cam chain so Im probobly gonna do a top end rebuild...Is there a kit to do this with all gaskets, seals, parts?

You say it smokes? Maybe its piston slap?
The person who says it cannot be done should not interrupt the person who is doing it.

What causes a piston slap? How do tell how big my current bore is?

A topend thats worn enough will make piston slap. Its exactly what it sounds like, the piston slaping around in the cylinder.
I would also do the cam chain as everyone else said. It would suck to install a new piston kit and have to tear it back apart for the chain.
You can in most cases pull the head and find marking or numbers on top of the piston to tell the current bore size. You will need a over sized bore piston kit. I'd pull the cylinder and take it to a local machine shop and have them look at it to find the current size and what size kit you need.

I would say it is the timing chain I had the same problem on a 400 ex.
Milkman took the words out of my mouth.
These old machines need timing chains AND sometimes tensioners.
I'm not educated on a Yamaha auto or manual tensioners, but they just hold something in place. They DON'T do much work, but the timing chain and gears sure do.....
I must admit, I almost never find worn TC gears, just a worn and stretched chain from doing it's job for 25 years.....
All our government does is distract us while they steal from us, misspend our tax $ and ruin our country
Ok time for an update...I went and got the impact screwdriver 85Tecate was talking about and got the cam cover off. One snapped halfway off so ill have to drill and tap that one not a big deal. So I was wondering how to tell the cam chain is too loose it feels pretty snug with some pay but it doent fell terrible. is it supposed to be tight

order an impact screwdriver set from sears not harbor freight. thise HF ones snap the tip soff easly. the craftsman will last you for years!! I've used mine a ton on trike rebuilding and brake jobs. so that's really your best bet.
