Are these a direct fit replacement for the main jets on a 1999-2002 carbuerated Yamaha R6?

I have a 1992 Suzuki GSX-R750 (not Cali model). My stock main jets are 127.5. I have a Vance & Hines slip on and I'm running lean so I need a bigger jet. I think these are what I need, but I don't know if I need the large round or small. Will either work?
gab1972 on Apr 12, 2012
BEST ANSWER: Thanks for your question! The large round main jet will be correct.
I have a 1977 kz1000. It has the vm26s. I want a 120 main jet. But y'all have a few different jets to choose from. I just want to know which jet would fit my carbs. Thanks for your time.
DANNY on Apr 8, 2011
BEST ANSWER: Thanks for your question! We would not be able to confirm if these would fit for you unless they are stated for the machine on the website in a kit. We would only be offering the OEM jets from Kawasaki which are the stock size that come in the bike.

Does the pack of 4 jets have to be the same size?
Jeff
null on Jul 1, 2010
BEST ANSWER: Thanks for your question! That is correct as the jets would not offer a mix and match pack. Most of these jet kits are sold for machines with 4 carbs which would need all of the same jet sizes.

It fit perfectly! After changing all the jets,floats,needles,gaskets, and cleaning the carbs on my new 87 fz700 project it runs smoother all the way through the rpm's than it has since it was made probably. With a near complete rebuild on the entire bike this addition to it definitely was one that stood out the most. Thanks Bandit for the great OEM/custom selection you have for this bike.

Sincerely

Great deal on these jets in a 4 pack. When you are in the jetting process, it can get expensive, and these 4 packs make it a little less painful.
