Jetting (Another thread) 2011 SD300

[biggstr6]

I followed this advise Below from the "more power down low Thread ",and it seems much better in the small field I tried it in Will have check the wide open somewhere else.

But I am much happier with the bottom right now.

Hope this helps some.

That didn't sound right for what Les used in his jetting kit. - so I just checked with Les and he said it was a DDK. #2 position (from top) and richer pilot...

But Les said he would go with what Roscoe (aka REVERUP) is using now - YZ needle/40 pilot/180 main... From Reverup's post on his new bike setup :

36mm Air striker 2 carb Slide #6.5 with notch.
Yamaha YZ 250 2 stroke factory carb needle N3EJ clip in center position #3
Pilot jet #40
Main #180
1 turn out on air screw
