looking for a needle for my Keihin

Recommended Posts

05 CR250r

06 RM Keihin a/s



I’m looking for a needle that can get me out of my dilemma


I tried the RM NECJ at clip4 and the off idle throttle response is fantastic. The only problem is that the needle is running borderline lean.

I also tried the N3EJ at clip4 and also runs borderline lean

I would like to find the equivalent NECJ as far the same dimensions at 0-1/8 so my a/s will fall in the same area with this pilot jet but the needle richer by 1-1/2 clips to get me back in the middle of the needle

I have a CEJ & CEK on order to use with a 50pj but now I believe these may also be too lean but not certain
