2005 CR250

My plug is black and wet when I foul them.

What can I do to correct this?

My Gas is perfectly Mixed.

Would just adjusting my Air/Fuel Mixture screw work?

If so what way?

Any other suggestions on how to prevent fouled plugs let me know please.

Also what is best plug in your own opinon for CR250 Motors?

since that is a new bike,i doubt your crank seal is shot,i would go with a smaller pilot or start riding the bike the way it was intended.your probably puttin around on it and its loading up on you,thats not the bike for leisurely trail riding.gotta open it up from time to time.also mixat 32 to 1 or so.a lot of the manuals on the newer bikes will tell you 20 to 1 or something like that.32 to 1 and you'll be fine.oil brand isnt important as long as its of quality.no lawnboy or weedwacker oil in your cr..:D
