Recommend me a needle :)

Hi everyone!

I've currently got my bike jetted at

Pilot - 42
Needle - CEK 3rd clip
Main - 178

The bottom and top end feel great, but I have a flat spot in the middle (I've played with power valve shims, and am at my most pokey), I'm also suffering 4 stroking at high rpm with constant throttle (not under acceleration).

This is on a 2006 EC300 with the round top PWK38 (AS1?), at sea level with ambient temperature from -10 to 30 centigrade (currently about the 20's). Can anyone recommend me a needle? Dropping the CEK to the 2nd clip makes the bottom end quite weak, and only helps the 4 stroking a little bit.

Thanks!

No recommendations, but constant throttle burble is related to throttle position, regardless of rpm.

2001 yz250 special order mx race needle.

Or something like that. Worked on my06 300

works on my 2013 too

07 yz250 needle, n3ew middle position. Really leans out the mid range. Might have to bump up the main to a 180 if you are on the pipe a lot.

yep mines a N3CJ, 3rd clip, 175 main and cannon silencer - runs sweet
KTM also sell the same needle cheaper

W/J diameter needles will be too lean on an AS1. Consider a G if going that path.

Consider a G? Anything more specific please?
