2018 EC250 jetting

Guys, stock is a little rich

I'm on 42/175 (stock), NEDW #3, a/s now 2 turns out (not stock).

Much better than stock, but still a tiny rich bog off idle even going from a/s 1.5 to 2 turns out. 13/50 gearing helps loft the front wheel in 2nd/3rd now for logs, etc but the jetting needs a further little play. Almost there.

After reading Gas Gas Rider & other reports elsewhere re the NEDW in a PWK38 in a 250 needing a slightly smaller main to compensate for the needle's richer end section, I'm going to drop in 40/172, NEDW #3, a/s 1.5 tomorrow - will report.

Lift the clip one.

42 NEDW#2 175 has been on the money for the recent 15-17 models. Probably be pretty close on a 18 as well.

Might fall a bit lean for your cold winters, but for current conditions right on. 13-50 has always been my sweet spot for gearing too. Makes 1st a bit of a granny/goat gear, and second and third much more usable.

Cool, Jake - I did think about that setting, too.

Will try it first..

Dropped the NEDW to clip #2, no real difference in the rich condition mid-revs with 42p/175m combo last weekend.

Bike was still boggy down low, too.

Put in 40p/172m, a/s 1.5, NEDW #3 today. Hanging a tiny bit before settling at idle on decel - a smidge lean, so I wound the a/s in to 1 turn. 28c, 0m ASL, 85 % humidity.

Felt smooth & grunty off idle - no bog whatsoever, no lean, snatchy feeling, either - and linear & really quite nuggety through to upper-mid. No knock or lean indication on decel. Incidentally, the mid-range on this bike is simply awesome.

Got the motor up to operating temp - bike starts, idles & runs cool. Bush test this week & I'll check the plug, too - BR8EG gapped @ 0.75mm.

Really great bike, very impressed so far

Gibnut were you in a YZ250 before? These new GG's look beautiful! Look forward to seeing one in the flesh.

They look even better in real life. Best looking dirtbike out there ( even compared to my pink Beta)

Looks like JD have got a new jet kit for the 2018 GG.
https://www.jdjetting.com/xcart5/all.../gas-gas-kits/
I'd be intrested if any body here has tried one on the new gassers.

JD blue worked well with my 2008 EC250 after trying a number of straight taper needles. Its comparatively an expensive option, but can be a time saver.

Is the NEDW a Suzuki needle?

Stinking hot out at the G yesterday - 32c, humid.

The bike is still rich off the bottom & spooging a bit, but because the power is so good off the bat, I'm ignoring it. No boggage, starting and idling well, plug is correct tan colour.

Got on the pipe a bit more yesterday - plenty of fuel in there, too! Animal.

Still about 10km/L. Pretty good.

Rich is the new lean, haven't you heard?

8hrs & she's running like a champ!
