Hi Thank you all for the info so far, I am pretty good with the spanners I have been around bikes for alot of years so most things are relatively easy to tackle, I am in Derbyshire, uk, I rekon we are 950 ft above sea level, temp god knows one day it 9' and the next in the 20s', I trail ride and do hare and hound stuff as well as time card events (Welsh 2 day enduro) etc. I use top quality relatively 2T oils at 50:1 with regular pump fuel... |

Ahhh, Derbyshire...a great corner of the world!
Personally I haven't tried the JD Jetting kit but I've heard alot of good reviews, a bit expensive for 2 needles and 4 main jets, but it should put you somewhere very close to the correct jetting. For your bike you'd need the JDG003 kit. I've haven't seen them for sale in the UK, except on eBay with delivery from USA... https://www.jdjetting.com/xcart5/jdg...category_id=65 On eBay... JD Jetting Jet Kit GasGas EC EX 250 300 2018 2019 Gas Gas JDG003... https://ebay.us/M2p95p Alternatively, if you don't want to spend that much or wait for delivery from the USA, you could try these two needles. I believe they are close to the Red and Blue needles contained in the JD kit. Red = NECJ Blue = NEDJ Can anyone confirm if I've got that right? The NECW that DocBrown has just suggested is one step richer than the NEDJ, so would also be a good starting point. See the chart below... chart.jpg |

Tell him to get some kits for sale on eBay UK, as far as I can see he'd be the only person selling them in Europe! I might buy one myself!

Hi all
I have also just bought a 19 a week ago and a similar issue ...have done about 100 miles running it in and started to wind it up ready to race at the weekend ..i too noticed a very loud bang/knock from the cylinder when shutting off and rolling down big hills and dose not run very smooth when pottering on the road around 1/8 throttle .. ..l have dropped the pilot jet down to 40 which has made a bit of improvement and the spooge out of the exhaust has about gone ..but still have oiled two plugs..both while warming up the bike ...if my thinking is right it is still rich on the pilot as the engine starts instantly with out choke? i am just going to check float height and try a 38 pilot jet as my next step ( my old 2012 racing i used to run 178 main 35 pilot and a EE needle ..but still was never good around 1/4 throttle ) at the moment I'm running Motul 800.. 90cc to 5 litres (55:1) 175 Main 40 pilot and the EF needle middle clip sea level about 12 to 14 degrees c. Isle of Man UK any help would greatly appreciated ...apart from this jetting issue the bike is fantastic and definitely confidence building compared to the 12 :O) Last edited by Herdy; 10-23-2018 at 04:31 PM. |

I measured up the JD needles. The blue is closer to an F diameter OEM needle. The red being around a H (slightly richer than the W). JD needles are dual taper only, and lean off heavily towards WOT. The Suzuki needles above are 3 taper and supply a load of fuel towards WOT. A closer comparison to the JD Red needle would be the N3CH which you see many people are very happy with. |
