Anyone have a spare JD Red?
Just wondering if anyone has a spare JD red needle to borrow. Wouldn't mind giving one a try when I go 250. I'm in Australia..

Yes, oh high priest of jetting, I would be humbled by you using it.

Yep, for the way/ where I ride the blue needle is better, you definitely feel a torque difference. Red in a 36 mm carb is more towards the zuk needles. I haven't tried the Yamaha or NO needles as I'm so happy with the blue. I'm a lugger in the tight and it's brilliant on hills as its hard to stall so you just keep opening the throttle at low revs and pulling in the clutch and it will walk up anything. Great for rutted red clay and loam hills.
I been noticing that my bike leans out on long climbs so I'm going to raise the float to 7 mm ( my bowl should be 6.5) if I can be that accurate, might change my jetting a bit. I wont be home till Saturday so I'll post it next week, pm me some details. Cheers. I'll send that suspension book as well.

Fantastic! There's no rush on it so I'll shoot you a PM next week (or on my days off).
I have a NOZJ here that I haven't tried yet either. Been really happy with the N3CJ. Very smooth and torquey off the bottom with a wickid mid range punch and a top end that almost reaches the moon. Great fuel economy to kick. I'll be very interested to see how they all stack up. |

The red is supposed to be based on the N3Cx needle. Blue loosely based on a DDK (same straight dia. with additional tapers).
The JD Blue from the generic kit, or older GasGas kit, is absolutely perfect in my 250 with the older 38mm AS I carb. Red is way too lean. Its probably too much to ask for it to work as well in the newer carb, as they are supposed to prefer leaner jetting. I wonder if the JD needles are different in the newer GG kit, or does he just package a different range of jets with the same needles and change the part #? I got so spoiled with my '07, just tried each needle, settled on the Blue in the middle clip, and just rode since '07 with just pilot and air screw changes when cold. I don't think anyone has experimented with a JD kit in a newer 250 with a 38mm AS II. |

Mmm I'm pretty sure someone would have run a JD kit in their 2011s. It just doesn't seem to be well documented on here. Thats somewhat the beauty of the JD. You spend so much on them that you find a clip pos that works best and keep it!
I ran the JD Red in my WR250F and found it to be stellar, which is why I'd like to try one in the Gasser. It very may well be too lean with the 250 top end though. I'm not even sure where I want to start with the jetting on it. Probably rich. Maybe 48 N3CJ#3 178. Has anyone run the YZ250 JD needle/KTM JD needles in their GG's? Would be interesting to see the variances. |

Jake,
I just emailed JD and asked about the needles with regard to the two different GG kits. I'll report back with his reply. I don't want to waste a lot of time jetting this bike, although 250s seem a lot easier than 300s. |

I have the red needle in mine. Worked better than the blue needle for me. It is however a 36 mm carb. JD's newer kit just contains a wider selection of pilots and mains.
