Hmmm. You don't know what plug the bike uses. You really need to buy a manual for this bike. Absent that, increase the amount of money in your bank account and take the bike to a dealer to fix. You have a problem. It may be jetting. It might be a crank seal. It might be a combination of things. But without more experience or a manual, you may need to seek the help of a professional or a friend who has dirt bike mechanical experience.
Jetting is not hard--explaining every single step without a manual is. It will require taking your carburetor apart several times (unless you're really lucky) and replacing things. A manual will have pictures that help a lot.
