2023 Rieju 300 factory jets.

I was surprised, a 170 and a 40 PJ.

I installed an NEDW but curious what I should jet at say 9,500'

Thanks.

Ud_luz, here are some reference points for you.

I posted this in ThumperTalk recently.

I have a 18 EC300 126 hours, runs extremely well. Original piston, power valve has not been adjusted or cleaned.

I am a senior rider & do not ride at full power very often.

Motorex Cross Power 2T 50:1 I get lots of spooge. To me, this means the motor is getting good lubrication. I just wipe it off w/ a paper towel at the end of each ride.

Riding in Colorado & Utah @ elevations 4,600' to 12,000'.

Carb settings: Needle JD Red in 2nd position, Pilot Jet #48, Main Jet 162

Runs a little rich @ higher elevations but fine for me

gez300 from Australia thought my Pilot jet was way too large. Its not.

Hope this helps
