I am worry about NECJ #2 is much lean? I was planning to use NEDJ #2 . NECJ is half clip leaner than NEDJ .

If you are worried run it in clip 3 and see what you think. The NECx needles are best run in clip 3, if they are run in clip 2 they lose the silky smooth power delivery they are known for.

As I said if the needle you have in clip 3 is still a bit rich you can go a half clip leaner by using NEDJ #2

Thanks n_green,

Hello guys,

Which Transmission oil i have to use? Syntetic or not? It says only "10W30 API SF or SG" in manual. I have not much options here. Ipone, Motul and Castrol.

Give Shell Rotella 15-40 a try, zero issues

I'm at NEDW#2 in my 250, but I like some snap too. You've got the right idea with your progression and testing. Try NECJ#3 and if its too rich or burbles go to the NEDJ#2 and you'll be right in the middle. Fuel economy should improve from what it was stock considerably.

Avoid N3xx needles if you want tame power. They transition onto the pipe quite a bit harder.

In the gearbox run whatever you want. Lots of people have their own opinions about what works and what doesn't. Quality oils with longer intervals or cheaper fluids more often. Just make sure the oil is suitable for use with wet clutches (no friction modifiers) and it should work well. Most find a thinner oil has less drag.

I agree completely with the above statement.
(and... In my 250 I like the NECJ in #2 position. )

For oil, I like a thinner oil with a high shear strength. Really good oil with these characteristics means no clutch drag with the close tolerances of the GasGas clutch.
Most of my two strokes get Rotella "Synthetic" 5w40, but my primary bike and those with Rekluse autoclutches get Amsoil synthetic 0w40 4 stroke engine oil. My utility engines and the CRFs and XRs get non-synthetic Rotella 15w40 (or Castrol or Valvoline 20w50). (Note: The Rotella 5w40 is not a true synthetic, but is able to claim such due to it's specific refining process and the additives used in it's multi-viscosity blending mixture.

Use what works well for you. I tried a lot of oils before I settled on my favorites.

I've used Amsoil 4T 10W with good results in the past, but of late have been using their sythetic transmission fluid which is designed for high torque applications. Its not exactly cheap, but on par with what I'd expect, and I can rack up quite a few hours on it before I start to feel the gears become a bit notchy. Clutch action is suberb.

I found this https://www.motul.com/en/en/products/oils-lubricants/transoil-expert-10w40?f[range]=21&f[viscosity]=28

Do you prefer any special transmission oil like this?

[Jakobi]

That will work. Give it a try and see if you like it.
