hey guys i just got my girls shee back together yesterday, i didnt do anything to the motor, just took off the air box lid, and it had 280 jetts in it with the needle 2nd from the bottem, i didnt have any good oil like klotz, so i went to the auto store and bought some castrol 2 stroke oil just to get her runnin, i mixed it 50.1, and she smokes BAD! and when i wrap on the throttle its not "clean" sounding. i thought the jetting was off so i changed the jetts to a 270 and moved the clip to the middle. it runs better but not great, i was adjusting the air bleeds out and it seems to be getting better, but would the shitty oil make that much of a difference? it also has T5's. and it was about 50 degrees out at 500 elev.
any ideas?
