How to compare USA and european jet needle.

Hello guys, by mistake i ordered a #DRS needle (USA) for my European model wr426f 2001. I changed it with the std. #DQR (EUR) needle and my bike runs fine. Does anyone now which EUR needle the #DRS is similar to??

I don't think there is a US vs. a EUR needle. The DQR needle is a 1/2 clip shorter than the DRS needle in length. They may have included the DQR needle with your bike if your exhaust is an little more open (less restrictive) than the US model.

The DQR needle is a 1/2 clip shorter than the DRS needle in length.

The DQR is also one size richer on the straight diameter (letter R vs. letter S), this governs mixture just off the pilot, before the needle comes on to the taper.
