250-500cc sorry another Jetting question .. '01 WR 360 w/PWK

I have a couple 'newbie' questions regarding fine tuning of my jetting, I understand there are several variables with regards to this 'black science' but nonetheless here goes...and since i had no interest when trying to sell i'm going to keep her for a while!

'01 Husky WR360 w/PWK Airstriker carb, run Yamaha R2 oil, 50:1, always fresh gas & clean filter. I have freshly rebuilt engine.
Air screw 1.75 - 2 out....hard for me to tell idle difference when adjusting this, only when it dies!
Red needle, position 5 (top position)
40 pilot
162 main
N. GA, ele 500-1000 feet
Plug is DARK Chocolate Brown

I could live with this jetting but think it will clean up with further adjustment. Thinking of 38 pilot, and adjust clip as needed.

Ride mostly single track and half the time at local riding area Highland Park in N. GA. Mostly 1/4 to 1/2 throttle usage, seems to carburate clean wide open. I believe i'm close with jetting, plug doesn't foul nearly as much as in the past; however when on long ride , 1/2 to 1 mile it loads up under constant throttle, will clean up with revving. I'm going to try lowering my pilot one size, adjust needle as necessary.


I have been using the attached Jetting Guide as a reference, should I? It seems to be thorough, having steps thru all circuits, air screw, pilot, needle & main.

1 - will bike smoke when lean?
2 - I have been using Spankys Jetting guide, good reference? http://users.conwaycorp.net/virtus/page2/speed/jetting.htm
3 - having trouble hearing "bog" vs "sputters"

Thanks!!
