I have a 2005 Rancher 350 4x4 ES. I ordered the HMF utility series slip on for it. I also run a K&N filter on it. HMF is suggesting a 142 main jet for it. My question is this: my friend just recently bought a jet kit for his 2006 trx450er and has plenty of jets left over, can I use the jets left from his kit? Just wondering if the jets on these two carbs. are interchangeable. Might save some $$$ if I can.

 

If they are both Kiehin carbs, which im sure they are, and they are both hex head jets, which i think they are...then they are interchangable.
