If you can turn the screw around that much and see no difference it sounds like the pilot might be to large , bogging is usually a sign of being to rich, unless you meant to say that the big surges when you whack the throttle.

 

Moving the needle clip up (moving the needle down into the jet) Is leaning it. Is that what you want?

 

No it's a bit of a bog I'd say unless u roll on gently. It's the stock pilot so aren't they usually too lean?

 

Yes I was going to lean it abit but if I move the clip to the second position the shims are flush against the top of the needle and it won't sit properly in the white spring holder.

 

I'm not understanding this shim / needle / holder interference thing. That shouldn't happen. Pics or a drawing?

 

Sorry yes I should have posted pics.
I managed to move the clip to the second position down but haven't ridden the bike.
From my 2 stroke years I remember that the pilot circuit seemed to make a differnce to the main circuit and adjusting the pilot screw made noticeable differences.
I'll try to post pics.

 

Have you had any luck resolving this?

 

Yes sort of. I moved the clip up to the 2nd position. It smoothed out the transition. But, I'm still thinking I will try a kdx snorkel and a smaller main because I'd rather have a nice sounding exhaust than a loud intake noise.
I'll post when I'm done. The bike runs very well right now so except for the noise I'm happy.
