keihin PWK information wanted

[Pauloz]

Hi

Could someone point me at a diagrammatic and manual/tuning guide for my carby from a 2011 ec300 - its the Keihin PWK 36mm. (FK0261 WAV)

I have looked and if it is under my nose I cant see it.

Thanks in advance.

The 2011 owners manual (https://gasgas.com/en/manuals) only contains a correction table for various temperatures but no jetting chart.

The factory setting is a good point to start with. Change jetting according to temperature and altitude. You may find good jetting data here:

The stock needle N1FE needs to be modified. First choosing some sturdy linesman pliers, cut into 2 or more equal lengths.

Problem 1/2 solved.

NEDJ needle from an RM250 is my vote.

NECH here, when I can finally get out I'll sort out which needle notch

Thanks for reply guys.

As it turns out there is JD kit in this carb.

I will stand down now.

Just as a side note, I went from JD to NECW and the bike run well but very aggressive. I then took the NECH, which is one full clip richer than the NECW and the bike runs a lot better now
