Pardee208 Posted March 17, 2008 Report Share Posted March 17, 2008 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?

Pardee208 Posted March 17, 2008 Author Report Share Posted March 17, 2008 There is a BIG difference between Castor and Castrol oil.

derfnigel Posted March 19, 2008 Report Share Posted March 19, 2008 if you use cheap oil you dont want to mix 50/1 the yamaha manual says 32/1 for yamalube 20/1for anything else =cheaper .The less oil you run the richer the mix more fuel for same amount of air not richer as in oil compared to fuel but fuel compared to air.I run castrol super 2 and mix 24/1 im jetted 280 w/o airbox lid, k&n and fatty pipes at 2500 elevation.Runs like a top Quote Link to comment Share on other sites More sharing options...

I use to run spectra 32-1 in my yz and I had to hold it WOT so it wouldnt foul a plug. after learing more about oil and mixures i ran 50-1 klots r50 and it runs great now. Oil has a big difference how how your machine runs. just my $.02 Quote Link to comment Share on other sites More sharing options...
