Ec 300 jetting uk settings

[Dazlar]

I?ve had a few gas gas 300?s and all run spot on from new so never looked at the carb settings.
I?ve just got myself a toy to green lane on. Ec300 2007-2008 mint but runs shite.
Tick over is good.
Bottom end pulls well, takes a couple gears to clear when riding at low speed.
Somebody has been trying to get thing right the settings are.

Spoke with Kev at gas gas uk

AS 1-1/2 out..

That?s just gonna make it run richer right. Any input would be great on this. I?m a tech rider like it crisp.
It’s got an FMF front pipe. If that makes any difference..
Thanks Darren
