250-500cc WR300 with PWK Air Striker ReDo

I put a PWK on my 2011 WR300 not to long ago, was running a 170/42 with a #7 slide and a N3EJ needle from a YZ250. I picked up this carb from a buddy that had a early 90's Yam WR250, but it had been scavenged for parts over the years. Another riding buddy pick up another PWK at a swap meet and I "borrowed" the needed parts from it, Including the jets/slide and needle. I also acquired an other smaller bore PWK and have some old PJ's laying around for parts too... When his son's older YZ developed some problem he asked for it back... So I brought the CEL needle and machined 1 of the 2 spare #5 slides I had laying around to a custom #7.25.. I was getting some spugge out the tail and was trying to clean it up... The difference is very noticeable, it is more responsive, seemed like it woke the bike up a bit...

I have a pwk i'm going to try this weekend. Since we are pretty much at the same altitude and reall not that far away from each other, your setting will prob work.
