N1EF v N1EG needle question
Hi all
I have 2 needles that I'm experimenting with, an N1EF and a N1EG. I know the N1EG is leaner, but what I'd like to know is if there is any overlap? How does N1EF clip position 1 (leanest) compare to N1EG clip position 5 (richest). I'm sure you'll understand what I mean. Thanks, Dave. |

There is next to no difference between the two.
Length and taper profile is the same between them. The only difference being the diameter of the straight section. The G is .01mm thicker (leaner) than the F. This particular needle has a very short straight section prior to coming into the first taper which also reduces the throttle positions covered by it, adding to a very minimal change. |

Do a search for needle suitable for the model. Then throw away what you have..
In the bin. It's too tempting but wastes time. They are rubbish.

Thanks for the advice/info Jakobi and F5.
Against your advice F5... I decided to persevere with the N1EG needle, only because I had time on my hands today and don't have easy access to any other needles at the moment. To my surprise I managed to dial my jetting in just where I want it, I'm really pleased with the results. I know the N1EG Needle gets a lot of negative remarks, but together with a 38 Pilot Jet, it's transformed my bike. It idles nice, it's clean and crisp straight from idle to all throttle positions, pulls hard. I'm having to adjust my riding position, sitting further forward to help keep the front wheel on the ground. Maybe I've just dropped lucky and the N1EG suits my carb/bike. It's a well used 2004 EC300. One thing I noticed is it's very sensitive to clip position. On notch 4 it won't start properly, keeps wetting the plug. At notch 3 and 2 it won't pull cleanly at 50% to 75% throttle. At notch 1 it works great. Summary: 2004 EC300 with PWK38 AS1 Carb 38 Pilot Air Screw 1 turn out N1EG Needle Clip at 1 (leanest) 170 Main Jet Throttle slide No.7 (Stock) Running on 98 Octane Unleaded from the supermarket petrol station. Ipone Samourai 100% Synthectic or Motorex Power Cross 100% Synthetic both at 2% (50:1) I'm in South of France, 15'C to 35'C at altitude 0 to 1000m Last edited by Davehuge; 10-07-2017 at 05:13 AM. |
