Keihin CVK 30 Main Jets

Hi! I have a Beta RR 125 LC buyed in 2017 (it's a MY'16, so Euro 3). One year ago I cut the B5 cable and I installed a Scalvini Full Exhaust. Since today, the bike worked well without installing a bigger Main jet (I think it's a 122). The bike was losing power only in Winter when the temperature felt down under 5/0 degrees (and the bike was cold). I live in Lombardy (near Mantua) and we reach 35 degrees during the Summer. Today I also installed a TwinAir filter. Here's the question:
What dimension of Main jet to install and what Main jet is it? (Is It an M5?) And where to find it? I searched on the internet and also in this forum but I didn't find where to buy online.

Thank you so much and have a nice weekend!

Hi,

On this Website you will find the Parts you Need.

Perfect! Thank you very much. Is It a good compromise 130? Or is it too much?

I think 130 is ok, but for only 4 € per piece you can buy a 125 or 135 to Test for the best.

Best regards

Yeah you're right! Thanks!

Bye bye
