Hey guys just getting into off road and I have a 2005 yz250 2 stroke. the bike was bought brand new and i have about 10 hours on it, granted i'm not constantly running wide open but im getting on it, but i keep going thru spark plugs. i was running the yamaha r2 oil with a 32:1 ratio and was running to rich, ii was then told to try running the synthetic amsoil at 50:1, and i'm still going thru plugs. when i say going thru plugs if im out for a 12 hour day at the track i'll go thru 3 plugs. what im wondering is what othe adjustments can i make so i dont go thru as many plugs.
should i ....drop the needle
.....air gas mixture
i'm at a loss anyone with any suggestions would be appreciated
