Mikes does "include" one size bigger and one size smaller jets when you purchase the kits.
I reposted because I did it wrong the first time.

I didn’t get any extra jets with my set. They feel smooth but such a prick to dial in. They are running super rich and I’m over it!
Changing it to two into one now with VM34 duck it

Maybe not but all I know is I got them with the kit I just got about 2 months ago. Came with 2 extra main jets and 2 extra primary jets.

Ok. All I am dying to know. Is where does the vacuum line f on the petcock hook up. Please god. Someone tell me.
I don't believe the puke system was designed to work with vacuum petcocks.

Oh. My. God. I didn’t get that. I didn’t know there was a kit for the keihin carbs... holy... wow. I’m such an idiot. That website is so non informative for someone brand new. Like myself to the XS world. Oh my god. I’ve just wasted so much money. Well. Hopefully mikes will help me out and understand, huh? Bummer.

There are 2 kits, one assembled and one un-asssembled.

Hello there, Please do not give up so easily - I would like to say again. If you ever experience any issues or need technical advise, regardless where you purchased your items, please contact customerservice@mikesxs.net. The PWK carbs in question are a division of Keihin. These are flat slide carbs that will perform without concern. Aftermarket carburetor swaps will take some experience, you have changed the design of the original aspects of the motorcycle. In some cases professional assistance is required. MikesXS is available to assist with the novice that wants to be able to install these major attributes to his motorcycle successfully. There are only one inlet to each carb for fuel. That is the largest inlet on the carburetor itself. The smaller diameter with the colored hoses are vents only and are directed to the ground. These carbs will work with either diaphragm or typical gravity feed fuel petcocks. If you decide to keep the diaphragm petcock on your bike just use the "prime" position. This will gravity feed your bike. If the diaphragm petcock is operating correctly, the on position is actually off when the bike is not running on the original Yamaha factory set up. It will serve the same purpose in this case. If you choose to eliminate the vacuum petcock MikesXS offers p/n 20-0019 for a non-vacuum petcock.

The choke thing is individual. You really do not have to do both chokes to start. Here are a couple photos to assist

That looks to be a clean engine Techman!

How do you all find the jjm or jjm, jjk needles? Every time I search for them nothing comes up except the conversion chart that I don’t understand. Like I get the measurements, I can find that, but then it wants me to convert it to a part number and I’m just not getting it?

I’m having where it is a little to rich off idle and stumbles unless I roll into it. I saw the post earlier where mrriggs used a jjm needle but that’s not a clickable part to buy...and I’d like to know in case I need a different needle so I can find it on my own. Thanks in advance!

Hi mrriggs, I want to connect a mercury manometer to my carbs as you suggest but there are no fitting barbs on the provided manifolds to attach the manometer hoses. Where do you attach yours?
This is how I did mine... just drill and tape them to the barbs you have (I believe most use a M5)
here are some if you don’t have any.

Get the mounts with the barbs or some people drill and glue in barbs. I know where I can get you a new set with barbs. Pm me if interested. Need to pay shipping from Canada though.
