ec300 jetting

[Steve ROC]

I have a new 2009 ec 300 with stock jetting and I'm wondering what jetting would anyone recommend for 2150 feet altitude. Down the road I might get a JD carb kit but for now I'll just use my brass from home. Where should I start? Needle, main, or pilot? Any input would be appreciated.

I would start >>HERE<<.

What do you have for jetting now?

Slide 7
needle N1EF clip top position
pilot 40
main 178

This is what's in the bike now from factory.

i changed mine to 2nd clip from bottom i ride from 200 metres to 2000 metres and this works fine with standard factory needle and jet

Just got a JD Jet kit today, I'll play with that for now. I can see this will be a trial and error arguous process, I thought there would be some pilots and some sort of jetting chart with the kit, guess not. But I should have it dialed in in a couple of rides so that's good news.
