Easiest way to replace valve seals?

[Miguelito]

My bike smokes up alot when I start it up. Looks like thick, white...possibly blue smoke. I don't know. I suspect it could be valve seals. What is the easiest way that requires the least ammount of tools to replace these? Are there any gaskets I destroy and need to replace by getting down to the valve stems? I was thinking I just needed a spring compression tool, a pair of pliers, a few wrenches and the new valve stem seals and I was set.

There is also no writeup on here about it. That or its burried deep somewhere.

The manual covers that procedure well.
