Well the NEDJ arrived before the enduro and I fitted it on #2 with the 42 and 170 but quickly swapped back again. It started fine and the initial throttle opening was crisper but beyond 1/4 throttle the engine would quickly foul the plug and stop running. I didn't have time to play with it but I suspect it wants the needle dropping to the 1st clip and a smaller main.
It seems that my bike needs a leaner jetting. I still have to set the squish, which is probably a bit wide, so I don't know whether this is the reason.
