Been a while but haven't been able to get out much due to other commitments.
The NEDJ#2 was working well with 165 main and 42 pj with fuel consumption improved and pulling much cleaner than before.
I was able to wind the idle screw out a turn which allowed the air screw to come into play - previously it had no effect as so much air was coming past the slide.
So I was pretty happy with it until I went for a ride up in the mountains (around 1000m, 30C) at the weekend. The bike was almost unrideable with very little pull until the power valves opened. On hill climbs (long steep fire breaks) the I was struggling to keep the bike on the pipe in 2nd when it should have been able to fly up in 3rd or more. On technical climbs it was even worse as once it came off the pipe it wouldn't even pull up in 1st and I was unable to get up stuff that should have been well within my capability.
Back down the hill and normal service is resumed so it was nothing more than a bit of altitude sickness. I have dropped the needle to the #1 today which has removed the last bit of hesitation as the engine comes on pipe but that is close to sea level. No idea whether this will be enough back up in the mountains.
I am wondering whether the NEDJ needle is more sensitive to altitude changes than the stock needle - is that possible? I also think I will need to get a leaner needle than the NEDJ for riding up in the mountains (up to 2000m) since I am already on #1. I don't know whether I just need to get a needle which is a clip or 2 leaner or change the diameter or taper, and what about the main? Advice please...
In my current stock I have the NEDJ, the stock needle and N3CH which I haven't tried yet.
TIA
