Bike loading up

[welsh.Z.S.]

Hey guys, recently done a lot of slower riding (mainly spent the day on the pilot) due to taking a new rider out for the day so was just putting about as he's still learning, anyway the bike kept loading up with fuel which required me to clear it out a few times, current jetting is 42p, n3ch (clip 3) 175m.
Bike has an s3 extreme low compression head.
Would you go down a pilot size or lean it out 1 clip on the needle?
The bike in question is a 21 rieju 300.

How far out is the airscrew? First thing to experiment with.

I'd measure squish clearance. I set my old 07 at 1mm and found it ran a lot cleaner in real slow work. You get less unburnt mixture left over.

What do they mean as low compression? 11:1?

Hi , I'm not sure what the compression ratio is with the low compression head , hopefully someone else on here will know ..
I also have an ultra high compression insert for the same head I may use again at some point ..
I remember it ran alot stronger off the bottom & cleaner with this insert
