Main jet size for a NC23

[The Novice]

Frame is rrj, engine is rrj - carbs, i think they are rrj but the number i can see doesnt exactly match those in the haynes manual. see the pics below





hopefully the photo's work.....

code looks like it says 04A M CA I think i can assume its rrj - anyone got an rrk they can just check - urs should say 04B...... instead of the 04A. the code is just above the float bowls which you can just view through the gap between frame and tank.

If that is right, means my carb has the wrong jets, what do you recommend i get for it instead of the 110's its got in it. manual says 115 is standard for an rrj. mine has stainless headers and a can on it. I just want round about the right area

I would fit 115s as that's at least better than the 110s, but I would get it straight on a dyno to go from there.
