Default Ranger Ec300 Jetting

Hi all, newbie here, just bought a 2019 Ranger, fantastic bike but,
Id like some info on jetting?
Bike is standard, after running in for 400miles.
Main jet 160
Pilot 35
As 1.0
Needle has been changed to a NEDW, clip 2.
Much better idle to 1/4 throttle opening but it seems to lack a bit up top compared to the stock N1EF needle which was also on clip 2.
The stock needle was really spluttering at small/ part throttle, not smooth at all like my old 4 stroke 250.
Tried a 165 main tonight, and it was missing at wot?
Photo is from a ride on Sunday covering 50 miles of trials and lanes, with new NGK plug, last photo is from stock set-up with a Nippon plug.
I also have an NEDG needle to try?
Any ideas where to start guys? TIA
Sea level, North Devon UK.
Cheers Mark

Default EC Ranger Jetting

Hi Mark,
Did you get an answer for your jetting question?
I have an EC Ranger and was advised by the UK importer to set my carb up as follows:

Main: 160
Pilot: 35
Slide 7
Clip: middle

I am about to try this combo (change needle) this weekend, so if you are interested i can let you know how it feels.

I reckon you will be able to go a lot leaner and cleaner than a 42 pilot, most 300s with the bigger 38 don?t need that big. I just jetted a 300 with a 36mm and it is running a 35 pilot with a NECJ needle. Just an FYI.
Back on a gassy! 2018 EC300! 🤘

I just jetted the pilot for best throttle response. If i go any leaner with the air screw i get a bog...

She run well at light throttle with almost no four stroking
